Good video, helped me finally setup the BMS correctly. Here are important setting details you might need if the video does not work for you: 1. PbmsTools v2.5FN is NOT a newer software of the HS1.0.6 shown in the video (now 1.0.8 exists). I could not set the CAN protocol with the v2.5FN! 2. To change setting, you need to enter the password. It starts with 1, ends with 6 and is 6 characters long ;-). No need to confirm the password, just type into the field. 3. (For european users) You need to set the number setting in Windows to have a point . as decimal point (not comma , ), otherwise the checkbox lists won't prefill correctly and you will only see 3s instead of 3.01, 3.02 etc. Hope that helps!
Are you able to explain how to change the pace to a 15s from a 16s configuration. I purchased a Jaki 11.776kw to parallel with my alpha ess SMILE5 but the 13.34kw battery is only a 15s… 🫣 I should have checked this before…
Finally, a BMS that does the SOC reset properly! No more having to over-volt the battery, no need to stress the FETs by forcing it into a cut-off. One thing that I am unclear about though is whether the BMS turns off charging when the current tails off and it resets the SOC to 100%, or whether it just leaves the charging direction intact. The charge controller should be the one to actually turn off charging under normal operation, not the BMS.
I'll test this in a future video soon. The charge MOS definitely turn off but I'm unclear about the MPPTs and if they still supply power to the load and leave the battery alone. So much to test, OMG 🙃
@@OffGridGarageAustralia I have a Victron EasySolar II GX 48/3000 with 2x Micromall batteries each with a Pace BMS and windows software Family-BMS v1.1.635-38. I am pretty sure that when the BMS reaches this 100% setting, it turns the charging FET off. The charger does not seem to get any prior notice of this and the DC voltage jumps as the current turns off. In my case this voltage jump was so large that it bricked the SmartSolar MPPT 250/70 -Tr charge controller (part of the EasySolar but a recognisable retail device just inside the EasySolar case) with an MPPT Error 40 "PV Input failed to shutdown". This seems to be fatal to the SmartSolar, certainly not field repairable.
I started to watching your videos to learn about off grid solar. I wanted to learn about solar panels, batteries, Battery Management System (BMS)'s. I wanted to know about solar components that are readily available in the Asian market. Lately your topics are only on high end systems that are not readily available to backyard solar enthusiasts. Would ask that you would review the commonly available solar components. You used to be a tremendous resource to us. Thanks Dave
Thanks for your feedback Dave. I'm not a commercial channel like others are. I'm sharing here, what I experience in my garage when working with different systems. They can be DIY or as you called them 'high end' batteries or devices. Some technology may not be available in all countries, I'm not doing any research but only share what I have tested myself. At the moment I, m exploring these kind of BMS and technologies as there was a huge demand to look into the communication side of things. I have already tested a lot of 'consumer grade' BMSes in the past and there is not much new coming as the trend really goes to these pre-assembled batteries or larger systems where the communication and control mechanisms are a bit more complex. If you're not interested in that sort of devices, you can always skip the video and wait for the next one. The title and description should give you a good summary of what you can expect. Thanks again, Dave. I appreciate you're sharing your thoughts.
Pace is not someone who is making FW updates available on their website. Mostly these FW updates come from the vendor who supplied the battery. In case of the Pace BMS, I have not received any updates, so this is all stock FW the BMS came with.
14:19 Like I previously mentioned several months back, many factory-built-battery owners will use their battery upto 70⁰C because it is written on the product specs. (you actually answered back with "Many users really?" or something like that). Likewise, you witnessed it also on some occasions with these BMS default factory settings; definitely many don't know that 50⁰C is already too hot to touch (let alone 75⁰C) and will not bother lowering it. IMO, Factory Default Settings should be at a more conservative settings instead of having them at maximum. SAFETY FIRST not INSURANCE CLAIM LATER.
It is only recently that Jakiper seemed to give the okay to changing parameters. I can see why they wouldn't want people messing with things when they warranty their batteries for 10 years. But in this case their settings were not the best in the first place.
That Parameters tab just needs a drop-down box added to select the pack you want. Plus all the back end changes to make sure the parameters are read from and written to the selected pack.
Hey Andy & community, I can confirm from my experience that there is HARM TO DAMAGE the BMS when the POSITIVE is switched! I am using the Gobel PC200 BMS and now it is DAMAGED. 👉Pls. add new tests to the comparison sheet (see below). Here's my setup (unfortunately I can't share the schematic as a picture here): - the Gobel Power BMS switches the negative path - a 200 amps fuse is in the positive path On a discharge test with only 120 amps over several hours, the fuse blew due to overheating. The BMS was still running but showed a SHORT CIRCUIT. But there was definitely no short circuit on any of the cabling as ALL cables are protected by 6 amps fuses and all are intact. And here the drama begins: the SMD parts next to the fourth connection/terminals (for cells B13+, B14+, B15+, B16+) for the voltage probes melted. Unfortunately the BMS is damaged and no longer reports correct cell voltages. And guess which BMS I have used? It is the Gobel Power PC200. I am still in contact with one of the Gobel Power engineers for further examination... I can keep you posted if of interest. Let me know and feel free to propose a better forum/blog (maybe under the comments section of Andys' Gobel Power PC200 video?). As a proposal: + it would be beneficial to add another test category for "short circuit safe" to the BMS Comparison Spreadsheet: what happens with the BMS if the short circuit protection fuse is triggered (by it's test button)? @Andy: Did any vendor provide you with spare/test BMS to run such a test? + in case test equipment is available, doing an actual short circuit (with an nearly empty battery) would also bring some light into which BMS can safely handle such an extreme situation. Thanks, Bernd (from GER)
In the process of building my own battery with the Qishou 280ah cells. Amy was super helpful. Gonna use Daly BMS cause of availability at the moment of purchase but I also purchased a Heltec active balancer. Thank you Andy for the videos.
Hi Andy! and thank you again for this really great video!👍Do you remember I told you a long time ago that the battery do not communicate with each other. The connections between them are just for monitoring. The problem also is that the systems only follow the "Master BMS instructions" so it's not perfect,😕 But we can still say that these BMS are good BMS actually. (pending perhaps new developments and improvements)👍
They do communicate with each other- the bms keep the voltage of each battery close to the same by adjusting the current. Maybe you have older bms version ?
Can't wait so see the mystery BMS. I ordered 16 280Ah cells from Basen to make a 2nd battery and i not yet choosen the BMS. I was close to buy the 150A from Gobel some weeks ago but waited to see this one and now i want the Pace. But i will wait to order until i see the mystery one and finally have a "choosen one". Thanks also to pointing out the fused block terminal. Ordered 5 stacks so i can fuse also the previous battery.
BASEN 200amp BMS had brilliant pre set parameters. Start balance 3,45 OV protection 3.65v 100% state or charge 56v @2000ma I have been pleasantly surprised by the presets.
I have looked into the available documentation and, unlike the Victron systems, the Pace (et al) BMS are not really designed for bi-directional communications. They do update their (basic) status etc, but changing the settings is indeed cumbersome, where you need to connect to each individual battery. Where one could argue this only needed once in the beginning of the set-up fase and not used much afterwards. To me it shows how well thought thru the Victron system is, in that respect. But I agree it would be better if daisy-chaining the batteries would also daisy-chain their set-up and parameters, the BMS should communicate also to each other. As why only the Seplos shows that parameter could be that the other BMS have an implemention-bug in their protocol where they all report the said parameter into the incorrect frame (AFAIK the communication is fixed-frames) where why you do not see that parameter unless using the Seplos BMS.
It could be an advantage that each battery has to be individually programmed so that a failure in one does not mess up what is programmed in all the others.
Hey Andy. I have been tuning into you for a while now and love all you do. In regards to this BMS, are you sure it's a PACE ? On the Gobal website they have this PC200 listed as manufctured by Great Power and not PACE.
Sehr sehr gutes Video, sehr ausführlich aber damit bekommt man die China BMS zum laufen. Wichtigste hinweise für mich, jeden Akku einzeln mit Kabel anstecken und konfigurieren, auch wenn man jederzeit die daten von allen Akkus lesen kann wenn man am Main Akku angeschlossen ist, kann man sie nur mit einzelnem anstecken ändern. Viel Spass euch....... Achja und Komma auf punkt in Windows umstellen, Systemsteuerung, Region und Zeit, Datums uhrzeit und Zahlenformat ändern, Weitere Einstellungen, Dezimalzeichen auf . solange ihr was ändern wollt. Gruß Klaus
Hi Andy, you're still reading comments here? I have found out that the 100% soc reset also needs to have the cells in a delta below the value set by the cell delta voltage parameter (firmware version 3.0 I have). I was playing around with setting this parameter via RS485 (esphome and home assistant) even lower than 20mV. jFYI Nicholas
Great Lesson Insight. Wondering if All Server Rack Batteries I am seeing on other RUclips Channels are in the same immature development category? ... I now Wonder: Do EG4 server rack Batteries need to be configured individually if one decides to go there? 🤔
I have several of these sort of BMS from different manufacturers and none of them can be programmed and configured from a central point. With some you can set up one and then copy the settings across the other BMS through a file you save somewhere. But if you want to change one parameter, you need to logon to each BMS individually, regardless if they have communication setup or not.
Have you ever used 2 pace BMS on a Victron system? I have this constellation and sometimes only one BMS is displayed in the Victron system, but both are displayed in the VRM portal. This is very strange behavior that I cannot understand. However, the Battery Aggregator sees all BMSs. So the communication seems to work in principle.
Hi Andy, so, I will venture a guess to the heat sinked and non heatsinked fets, the side without the heatsink only switches hard on or hard off, the heatsinked side will probably be the current limiting side which means that the fets are operating in the linear region which means that they will get hot because they are being used like a "resistor",. Just my 2c though, I could be wrong,.
The current limiter is working with a PWM signal, so switching the FETs on and off with high frequency to limit the overall current. They still become warm by doing that. On the RN150 we have another layer of PCB with the current limiter and even this has a small heatsink. Yeah, very strange...
For normal usage, based on my recent testing, I'd start balancing at 3.40V and limit charging to 3.43, because I don't see much capacity gain to 3.45. I'd also limit discharge to about 3.13V too for the same reason. You might lose
Yesterday, I had a battery (48V/100Ah) on charge. SOC was at around 39% and solar pushed hard (around 35A). The charge voltage was at 3.42V and the balancer would have kicked in already. That is not great considering the low SOC. At this stage, the balancer will not balance the pack but unbalance it. Also discharging to 3.13V is too high if you have like 0.5C discharge current (even as a peak). You may have a very special setup and needs there to run such settings.
@@OffGridGarageAustralia Ah, interesting. I only have the 16 cells at the moment so I guess I'll have to hold off on those settings. But I'm looking at having three times that many paralleled at the cell level so keeping charge and discharge rate below 0.2C
The low side mosfets that switch on and off charge and discharge don’t need cooling because of low rdson. The current limiter does because it’s effectively a buck converter switching thousands of times a second which generates heat as they move through the millar plane. They could probably save money and eliminate virtually all of the heat by using ganfets and instead of having separate charge fets use the same for the current limiter. Or do what I did and use the data from a jkbms to control the amps coming in from the growatt unit dynamically as it reaches full charge since any charge controller already has a buck converter to step down to the battery and can already limit current so no reason to pay for it twice.
@@J0rd40 I hacked the serial coms for the geowatt to provide data to home assistant and same for the jkbmses. Then you just create automations as necessary that adjusts the charge current of the growatt based on SOC and max cell voltage of the jkbms. Plus, you can emulate float mode etc if you want as well the same way.
Hi Andy, your are a super great teacher for the BMS Magic! I’have a question about communication over the two Gobel BMS model. I have 2 RS150 BMS and now i look for building a third batterie with this gobel « PACE » BMS. Do you know if it’s possible to make them communicate together?? Thanks a lot for all I’have learn with you last two years. Anthony
Hi Andy, thanks for all the research you do. I am about to place an order with Gobel Power for 3x GP-SR1-PC200-Standard-HC 280Ah and they have suggested I also get a Battery Home Assistant Add-on Kit. Have you covered what this does anywhere in your videos? (I dont know if I should be getting the WIFI or LAN version)
Hey Andy! I Just Bought my First Victron Gear, Multiplus 3 48/3000 with 3 Pylontech US2000C Packs for 7,2kwh Brutto and 6,6kwh Netto. I Also Got an MPPT100/20 in the System with Cerbo GX and i use the Multiplus in the moment as an ESS and have 2kWp connected to an Growatt AC Inverter Which i had for like 2 years. Sadly i cant Plug my Panels in to the Victron MPPT because i have 5 in Series so about 180-200V DC :( Learned a lot from you will Build onto it! :)
Great vid Andy! A few questions! :) The 'Pack Fullcharge Voltage' setting (ie. 56v in your case)... Is this what the inverter also uses as its charging voltage if there is of course communication between BMS and inverter? Or does inverter get its charging voltage from a different setting in BMS? Also, when pack reaches 56v, is this also how the inverter knows to go into absorption mode? Or is absorption voltage set somewhere else in a different parameter? Then, in a scenario where inverter is NOT communicating with the BMS and it is a basic setup whereby all settings are set manually on the inverter, how does inverter know to go into absorption mode? Will it just use the manually set 'charge voltage' that was set on the inverter? Thanks!
Hi, I pointed out to SOK about the settings on SOK 48/100 batteries that also uses Pace BMS. I changed the settings as you did, but this is the reply from SOK Europe that does not mske any sence to me. Dear Thomas, For battery cell overvoltage protect, yes 3.65V is written in spec. When the battery reach 3.65v, the battery will be charged by constant current and constant voltage, and the constant voltage up to current is 0.05C. Our battery pack is charged in the current close to 0.2C, and then voltage will reach 3.7V. The charging will be stop. This is the way call “Standard charge method”, 0.5C constant current charge to 3.65v for cell, then switch to constant voltage charge until charge current declines to 0.05C. The cell Maximum charge current (continuous) is 100A. Which means that it can be charged continuously at 100A from SOC 0 until the voltage reaches the cut-off voltage. There is no problem with charging this current for a short time, and no need to worry that it will damage the battery. The parameter setting I sent to you is exactly our factory default setting. We don't know why most of them are not set correctly? So we suggest you can change all setting to that. And we are not understanding how this issue is about the old firmware bug in the Pace BMS??
I think if you can you should test a BYD system. They have good communication with Victron. Just one thing is the BMS will enter sleep mode if communication is lost.
Argh, that's bad. At least these BMS stay awake for 48h before going into sleep mode. As soon as charge comes in or comms start working again, they wake up. BYD makes HV batteries, I believe? That's not DIY any more though... far to dangerous.
@@OffGridGarageAustralia Yes not ideal, but they do wake as soon as charge comes in but requires the comms to continue charging. BYD does have a low voltage range (48V) I believe they have two models available, a 15KWh and a 5KWh. I may be wrong on this one but I'm sure I read that they support up to 64 batteries on a single system and using the 15KWh batteries would make that almost 1MWh of storage.
Andy I think the interface is from daly (but i could be wrong😊). I been using it for some time now. If you want I can send you the 3d cover for it. But I dont have a way to contact you. 😞
Great video, very useful! Thank you! Is it possible to make a top balancing on pace bms? Looks like one of the cells is not fully charged and is not balancing well.
I'm loving the videos as I'm wanting to get my own battery setup. Can you add into the spreadsheet whether the BMS has passive or active balancers and what level of current that they will use to balance. Also will they balance one cell or more than one cell at the same time. I'm wanting to get the 300ah batteries and from earlier videos you said a passive one just is rubbish. Or should I have a separate active balancer? thanks and keep up the good work!
Great video. You mentioned changing certain parameters on the Pace BMS e.g. cell I we protection. What are your ideal settings for a 48v (16 cell) lifePo4 please?
Hi Andy, thank you for the helpfull videos. I need to change the Inverter protocol as shown in your video. The PBMS Tools I can find is the version 2.5 which does not have the option to select the inverter protocol. Do you have a download link to PBMS Tools HS1.06? Thank you.
@@OffGridGarageAustraliathanks again for keeping us informed. Given all your investigation into bms’s now, if you were to build 2.0 again which bms would you use. Would you get a new one that talked to the other bms and batteries or stick with non communicating bms. Thanks again.
Excellent information, thank you Andy. From what I read on internet and what I have seen on your video, it seems our new svolt battery has the pace bms installed. I am trying to balance the cells, cell08 is always lower than the rest, max is 3.371v while others are from 3.456v to 3.485v at 100% charge. I am trying to balance while charging at 10A only, to keep it in charging mode as long as possible as it seems balancing only happens while charging. Not sure if this bms can balance continiously and not only while charging. I do not have bms software yet, so I can not change parameters. I would like to know if difference of 104mV is something to worry about and if balancing will happen within a few weeks of normal daily cycling. Supplier suggested 3.5v bulk and 3.4v float per cell. We have a grid supply situation here in South Africa called load shedding as utility can not supply enough power for everyone, 24/7. Our next power out starts in a few minutes and lasts for 2 hours. This is a daily occurence at present.
Thank you Andy, great info. I have the svolt battery with pace bms and bat. works great after I set up the bms according to your recommendations. Something I am not sure about, is the gap charge threshold under parameter setting. Any idea what the setting is for? Regards, Koos.
Hi Andy, My 2 x 15 kwh batteries have arrived. They have PACE BMS's in them. I am having trouble connecting the BMS to Victron Cerbo GX. Do the PINs need to be modified for the RJ45 cable that connects BMS Can port to the Victron CAN-BMS?
Tôi có 1 BMS Pace p16s50a, tôi muốn dùng nó cho pin 6s nhưng nó không cho set up liệu có Firmware nào chuyển nó thành 6S50A không ạ? Vui lòng tư vấn... Cảm ơn nhiều!
Hey Andy, if the master BMS reaches 48V it will report a discharge current limit of 0A to the victron System and this will shutdown all discharge right? Maybe you can test this? So it would not be a big problem if the slave BMS`s are set to 40v low voltage Thx for your videos again and again 🐸
It will request a discharge limit of 0A, that is correct but it will NOT shut down the inverter or MPPTs. It is not a protection setting. Usually, if there is a hybrid inverter connected it will simply tell the inverter to limit the current drawn from the battery and more from the grid. Until the point where DCL goes to 0 and the inverter uses no battery power and 100% grid power. With MPPTs, however, this DCL will be ignored as there is only one power source for them to pull energy from (the sun). So in my off-grid setup, DCL may go to 0 but nothing gets shut off.
I have an Allith power storage 200AH 51.2V with Pace BMS (P16S200A-21382-3.0T). And after the winter and a long low SOC level, I unfortunately always have an OVP error when I load above 99% SOC. I use an SMA Sunny Island 4.4 and have already reduced the charging power from 3300w to 1100w because I want to give the BMS more time for balancing, but unfortunately it doesn't help. Should I just lower the voltage at which a cell should start balancing a little so that balancing starts earlier?
Dear Andy, any chance to identify the type of the connectors used on the new Pace 200A BMS to connect the balancer to the cells? There are four connectors, two of them are 6 pin and two are 7 pin once. But I don't know the type. I am planning to design an adapter to connect a Neey 4A balancer to the cells without breaking anything.
Hi Andy, do you know, why the Pace BMS has a SleepVoltage of 3,15V? Below this Voltage, the BMS is going to sleep after 5 minutes. It doesn’t makes sense.
The BMS goes into low power mode after 24h if no communication, no charge or discharge have occurred, and all cells are under 3.15V. The time can be changed in the settings (Resting Delay, sits on 1440 which is 24h by default)
Hi Andy, I have lithium battery with pace bms I opened it in my PC but I didnt find the inverter protocol in it like you. Is my pace bms is not like yours and there is no inverter protocol in it or I am doing a mistake like version of bms tools or anything else.
Hey, I just got the new pace BMS that has, heating function, fan cooling function,!!! active balancer control function !!!, haven't tested it yet since I burned the Voltage sensing IC and waiting for replacement, are you "plan"ing on reviewing it ?
Hi there I have the USB to serial to r232 suggested by your website but I cannot get the software to communicate to the bms. It just says device A device attached to the system is not functioning when trying to open the port. has anyone else had this issue. my batteries are from top lithium battery in VIC and I believe the bms's are the P16S100A-0004-20A. i think one of my cords is a dud ?
Andy , can you post all your Pace bms parameter settings when you get everything all set up how you like it ? I changed the jakiper setting on mine by just moving the rs232 , I didn't need to disconnect the other battery interconnect cables or change the dip switches.
I can also connect with RS232 without changing the address with the dip switches. @Andy: Maybe you have to select the right address in the top right corner befor you connect.
@@OffGridGarageAustralia well I am using 2.04 version of software with 88888888 password that Orient Power had on their website ( not sure if still there). I couldn't find the newest 2.06 software you were using. Tried downloading from Aussie Orient power site but file wouldnt run any program.
@@OffGridGarageAustralia Also maybe makes a difference is that I shut software off , plug in different battery rs232 and then start software again . No other changes to dip switch or interconnect cables.
@@LarryKapp1 Ah, OK, I'll try that. It still does not really help because someone needs to be onsite to do all that. I would rather have a solution to fully remote control the whole system through a small Windows PC (NUC or similar). If someone needs to be onsite anyway, there is not much gain. Hopefully, they will get there eventually and make a software which does all that without touching the battery or cabling. Or even having to change DIP switches 🤦♂
Hi Andy, I have run into a problem which I cant fix . My inverter is a MPP Solar 5048MGX and my battery is Chinese brand Sunwise. The battery has a Pace 48V 150A 15S BMS. I have found the correct pbms tool to change the protocol but it won’t change it “Fault”, I have also used the other pbms tools programme to access the settings and tried resetting it in the “System config” section, but that doesn’t work either “Fault”. It also states “Fault” when I want it to read the info! It does however allow me to change parameter settings. The protocol is set to “Paceic” I need to change it to Pylontech as the Inverter has the pylon option. Any Ideas? Much appreciated.
@@OffGridGarageAustralia I suspect that they where thinking that you may not be charging all day long at 200 amps, maybe discharging all day long at 200 amps seems moor logical, they could be just more efficient fet’s
Yes, I have one on my website, have a look at the high power variable power supply. They make them with 30V and 100A as well. They work great for charging. I use my 60V 20A all the time for that purpose. Very good quality but not cheap though. off-grid-garage.com/measurement-tools-and-analisers/
is it able to communicate with the venous OS on raspberry pi, if yes how did you connected can to pi(is it via any USB converter specified in the other video of JK and Daly communication). Thanks
Can anyone tell me if there is a managed bms that can talk to a selectronic inverter. I contacted Batrium no luck there. Has anyone have experience with the selectronic inverter? Thanks.
No idea, you have to check the specs and manual of the BMS for such a special setup. If in any doubt, I would contact Gobel directly and ask this question. 51V batteries in series is not DIY any more.
hi Andy, i have recieved a pace bms version P16S200A-21587 -2.02 i checked your spreadsheet... i noticed in this version the CVL is not taken from the Pack FullCharge voltage but from the Pack OV Alarm setting .. any one here noticed the same? and how to setup the config now with this in mind Andy, something you could check ? regards from wet/cold Netherlands
@MrRschutte I have a Victron EasySolar II GX 48/3000 with 2x Micromall batteries each with a Pace?? BMS CY-IH001-B100LT48-V1.0.0 and windows software Family-BMS v1.1.635-38. In my case the CVL as shown in the Victron console is 55.7 V and nowhere in the BMS software UI is that number, nor is it anywhere in the exported settings file.
They usually close a relay contact when something happens. For example, the close one contact if there is an alarm and close the other contact when there is a protection status. This can then trigger external mechanics, like turn on an alarm light, a siren or turn on a charger/generator. They change the functions from FW to FW and it is really annoying that the user cannot select what function a relay contact should have.
Hello Andy, thanks for all your great videos!! One question about this one - when you look at the BMS Canbus screen on the Cerbo is shows (@19:04) “ERROR- ACTIVE” as the state ? Even after you set the dip switches - it stays the same. Is this normal ? I have the same on my Cerbo. Also on your “details” for the BMS you get cell status “high cell- low cell” is this something you added as mine does not show this from a different PACE BMS. Thanks
Kia ora @Over_50s_DIY_Vanlife, I have the same "ERROR-ACTIVE" on my Venus GX device console. I had it before the batteries were connected and still now.
@@grahamharris1985 my system seems to work well but I did lose all the SOC from the batteries as I had a very small current (0.4 amp) which the BMS didn’t pick up so I now have added a Shunt as my battery monitor
You would think with all the BMS’s and inverters on the market that they would standardize the communication. Basic settings that all BMS’ use would be the same along with a battery ID for each BMS/Battery. This way if you don’t know what kind the BMS is just pick Basic/Standard in the list. IF an inverter has a special feature that is not common then you would need to pick that inverter to see those advanced features that are built on top of the already agreed on basic feature and communication. It’s not rocket science, even governments can force this standard saying that without it can be a safety hazard or possible fire risk.
I think your neighbour is taking down some trees to circumvent shadowing on his solar panels? (joke!) Back to the topic; I assume all those Pace BMS all have the same firmware? And also support bluetooth? As for why not all Mosfets are having a huge heatsink pre-installed, I would assume those without a heatsink are used for the balancing currents (max 5 amps) and therefore wouldn't get that hot. On the other hand, the way the board is mounted, could it not be that those Mosfets without heatsinks are touching the inside of your battery-case and use your case as a passive heatsink? As for the switch, I like the new switch better as you have a far better visible que that it is on or off, with the pushbutton it is harder to see, I believe. I agree, M5 instead of M6 (or better: M8) is not really a good choice and they should have included the bus-bar, makes it a more complete solution. The good news is there are "coffee-machine" switches in a round version. Even with a LED and different colours.

Any chance the "Export Datas" tab would send or allow the export of parameters from the master to the slaves while still connected as a parallel pack? Realizing the capacity differences will still force individuals to be programmed separately, would be nice to know if the capability exists in case one were to have multiple packs of the same capacity cells.
It's not possible, you have to connect to each port to affect the settings, you can only get specs, (SOC, Current and voltage) over the rs485 daisychain, I have 2 packs with the same style BMS's and software, I have tried, a massive PITA, you can only change the settings of the pack you are physically connected to.
The balancer is only 50mA passive. It may work but won't balance any larger battery cells. Active balancing is needed. Yeah, some people may be lucky and have very well matched cells and the 50mA could be enough but over time, when they age, they tend to drift more and more and the balance won't cope any more.
So can this bms be used in "starting" lithium battery? if I understand correctly full cutoff is not hard and alternator can adapt to full pack and bms hard cutoff that burns alternator will not occur? If not, how those start lithium bms work?
Good video, helped me finally setup the BMS correctly. Here are important setting details you might need if the video does not work for you:
1. PbmsTools v2.5FN is NOT a newer software of the HS1.0.6 shown in the video (now 1.0.8 exists). I could not set the CAN protocol with the v2.5FN!
2. To change setting, you need to enter the password. It starts with 1, ends with 6 and is 6 characters long ;-). No need to confirm the password, just type into the field.
3. (For european users) You need to set the number setting in Windows to have a point . as decimal point (not comma , ), otherwise the checkbox lists won't prefill correctly and you will only see 3s instead of 3.01, 3.02 etc.
Hope that helps!
Where can I download the new version? Thanks
Andy, you sre the battery pope !
👍👏❤️
No one else has teached us so much about LiFePo4 and BMS.
Oh, thank you very much, Juergen. I appreciate you feedback and kind words.
We’re the ones that got Victron to make this BMS Victron compatible. It used to stop charging at 52.4v for 15s batteries.
Are you able to explain how to change the pace to a 15s from a 16s configuration.
I purchased a Jaki 11.776kw to parallel with my alpha ess SMILE5 but the 13.34kw battery is only a 15s… 🫣
I should have checked this before…
danke aus Deutschland für deine tollen Beiträge ...........ohne dich wäre ich manchmal nicht auf den Baum gekommen Christoph
You really came a long way since you built battery 1.0. Indeed an interesting development to watch. Loving your channel a lot.
Thank you, yeah, it's been a while since we built the 1.0. Good old times, everything was new and unexplored. We certainly learned a lot since...
I have to say, I see nothing wrong with that power switch. Very simple, and no way to confuse whether it is off or on.
Finally, a BMS that does the SOC reset properly! No more having to over-volt the battery, no need to stress the FETs by forcing it into a cut-off. One thing that I am unclear about though is whether the BMS turns off charging when the current tails off and it resets the SOC to 100%, or whether it just leaves the charging direction intact. The charge controller should be the one to actually turn off charging under normal operation, not the BMS.
I'll test this in a future video soon. The charge MOS definitely turn off but I'm unclear about the MPPTs and if they still supply power to the load and leave the battery alone. So much to test, OMG 🙃
@@OffGridGarageAustralia I have a Victron EasySolar II GX 48/3000 with 2x Micromall batteries each with a Pace BMS and windows software Family-BMS v1.1.635-38. I am pretty sure that when the BMS reaches this 100% setting, it turns the charging FET off. The charger does not seem to get any prior notice of this and the DC voltage jumps as the current turns off. In my case this voltage jump was so large that it bricked the SmartSolar MPPT 250/70 -Tr charge controller (part of the EasySolar but a recognisable retail device just inside the EasySolar case) with an MPPT Error 40 "PV Input failed to shutdown". This seems to be fatal to the SmartSolar, certainly not field repairable.
I started to watching your videos to learn about off grid solar. I wanted to learn about solar panels, batteries, Battery Management System (BMS)'s. I wanted to know about solar components that are readily available in the Asian market. Lately your topics are only on high end systems that are not readily available to backyard solar enthusiasts. Would ask that you would review the commonly available solar components. You used to be a tremendous resource to us.
Thanks

Thanks for your feedback Dave. I'm not a commercial channel like others are. I'm sharing here, what I experience in my garage when working with different systems. They can be DIY or as you called them 'high end' batteries or devices. Some technology may not be available in all countries, I'm not doing any research but only share what I have tested myself.
At the moment I, m exploring these kind of BMS and technologies as there was a huge demand to look into the communication side of things.
I have already tested a lot of 'consumer grade' BMSes in the past and there is not much new coming as the trend really goes to these pre-assembled batteries or larger systems where the communication and control mechanisms are a bit more complex.
If you're not interested in that sort of devices, you can always skip the video and wait for the next one. The title and description should give you a good summary of what you can expect.
Thanks again, Dave. I appreciate you're sharing your thoughts.
Hi Andy, if you expect, that all the pace BMSes are reporting correctly, it might be worth to have them all on the newest firmware level.
Pace is not someone who is making FW updates available on their website. Mostly these FW updates come from the vendor who supplied the battery. In case of the Pace BMS, I have not received any updates, so this is all stock FW the BMS came with.
14:19 Like I previously mentioned several months back, many factory-built-battery owners will use their battery upto 70⁰C because it is written on the product specs. (you actually answered back with "Many users really?" or something like that). Likewise, you witnessed it also on some occasions with these BMS default factory settings; definitely many don't know that 50⁰C is already too hot to touch (let alone 75⁰C) and will not bother lowering it.
IMO, Factory Default Settings should be at a more conservative settings instead of having them at maximum. SAFETY FIRST not INSURANCE CLAIM LATER.
Yeah, I can only advise anyone to check the settings of their batteries and BMS if they buy one. Regardless if it is DIY or pre-assembled.
It is only recently that Jakiper seemed to give the okay to changing parameters. I can see why they wouldn't want people messing with things when they warranty their batteries for 10 years. But in this case their settings were not the best in the first place.
That Parameters tab just needs a drop-down box added to select the pack you want. Plus all the back end changes to make sure the parameters are read from and written to the selected pack.
Yeah, I thinks so too, it's just a software update away.
Hey Andy & community,
I can confirm from my experience that there is HARM TO DAMAGE the BMS when the POSITIVE is switched! I am using the Gobel PC200 BMS and now it is DAMAGED. 👉Pls. add new tests to the comparison sheet (see below).
Here's my setup (unfortunately I can't share the schematic as a picture here):
- the Gobel Power BMS switches the negative path
- a 200 amps fuse is in the positive path
On a discharge test with only 120 amps over several hours, the fuse blew due to overheating.
The BMS was still running but showed a SHORT CIRCUIT. But there was definitely no short circuit on any of the cabling as ALL cables are protected by 6 amps fuses and all are intact.
And here the drama begins: the SMD parts next to the fourth connection/terminals (for cells B13+, B14+, B15+, B16+) for the voltage probes melted.
Unfortunately the BMS is damaged and no longer reports correct cell voltages.
And guess which BMS I have used? It is the Gobel Power PC200.
I am still in contact with one of the Gobel Power engineers for further examination... I can keep you posted if of interest. Let me know and feel free to propose a better forum/blog (maybe under the comments section of Andys' Gobel Power PC200 video?).
As a proposal:
+ it would be beneficial to add another test category for "short circuit safe" to the BMS Comparison Spreadsheet: what happens with the BMS if the short circuit protection fuse is triggered (by it's test button)?
@Andy: Did any vendor provide you with spare/test BMS to run such a test?
+ in case test equipment is available, doing an actual short circuit (with an nearly empty battery) would also bring some light into which BMS can safely handle such an extreme situation.
Thanks,
Bernd (from GER)
In the process of building my own battery with the Qishou 280ah cells. Amy was super helpful. Gonna use Daly BMS cause of availability at the moment of purchase but I also purchased a Heltec active balancer. Thank you Andy for the videos.
Thanks for sharing. Good to know QSO is still in the market and up with their standards.
Hi Andy! and thank you again for this really great video!👍Do you remember I told you a long time ago that the battery do not communicate with each other.
The connections between them are just for monitoring.
The problem also is that the systems only follow the "Master BMS instructions" so it's not perfect,😕 But we can still say that these BMS are good BMS actually. (pending perhaps new developments and improvements)👍
They do communicate with each other- the bms keep the voltage of each battery close to the same by adjusting the current. Maybe you have older bms version ?
Maybe😁
Can't wait so see the mystery BMS. I ordered 16 280Ah cells from Basen to make a 2nd battery and i not yet choosen the BMS. I was close to buy the 150A from Gobel some weeks ago but waited to see this one and now i want the Pace. But i will wait to order until i see the mystery one and finally have a "choosen one". Thanks also to pointing out the fused block terminal. Ordered 5 stacks so i can fuse also the previous battery.
If you can wait a few more weeks, there will be a brand new JK coming. With AB!
BASEN 200amp BMS had brilliant pre set parameters.
Start balance 3,45 OV protection 3.65v 100% state or charge 56v @2000ma
I have been pleasantly surprised by the presets.
I guess, they had enough complaints or at least improvement suggestions. They are slowly getting there.
@@OffGridGarageAustraliawell I’m a great believer in giving people a chance to improve, just look how far neey have come 😉
Fun as always, it is good to have a fuse in case of the wurst! 🙂

They are great. Using them for everything.
Excellent review. Very entertaining. Good details - as always. Thanks for sharing
Thanks for your feedback!
Plain clear sky's today. Is your neighbour building his house furniture over there. 😂
I don't know what he did but it is quite now. Maybe the machine killed him finally😂
@@OffGridGarageAustralia LOL 😆
I have looked into the available documentation and, unlike the Victron systems, the Pace (et al) BMS are not really designed for bi-directional communications. They do update their (basic) status etc, but changing the settings is indeed cumbersome, where you need to connect to each individual battery. Where one could argue this only needed once in the beginning of the set-up fase and not used much afterwards.
To me it shows how well thought thru the Victron system is, in that respect.
But I agree it would be better if daisy-chaining the batteries would also daisy-chain their set-up and parameters, the BMS should communicate also to each other.
As why only the Seplos shows that parameter could be that the other BMS have an implemention-bug in their protocol where they all report the said parameter into the incorrect frame (AFAIK the communication is fixed-frames) where why you do not see that parameter unless using the Seplos BMS.
It could be an advantage that each battery has to be individually programmed so that a failure in one does not mess up what is programmed in all the others.
Cant believe I wasnt subscribed before!!
Hey Andy. I have been tuning into you for a while now and love all you do. In regards to this BMS, are you sure it's a PACE ? On the Gobal website they have this PC200 listed as manufctured by Great Power and not PACE.

Hi Andy,
you're still reading comments here?
I have found out that the 100% soc reset also needs to have the cells in a delta below the value set by the cell delta voltage parameter (firmware version 3.0 I have). I was playing around with setting this parameter via RS485 (esphome and home assistant) even lower than 20mV.
jFYI
Nicholas
Great Lesson Insight. Wondering if All Server Rack Batteries I am seeing on other RUclips Channels are in the same immature development category? ... I now Wonder: Do EG4 server rack Batteries need to be configured individually if one decides to go there? 🤔
I have several of these sort of BMS from different manufacturers and none of them can be programmed and configured from a central point. With some you can set up one and then copy the settings across the other BMS through a file you save somewhere. But if you want to change one parameter, you need to logon to each BMS individually, regardless if they have communication setup or not.
Wieder danke fürs gute Video 😊👍🤗 weiter so danke 👍👍
Thank you.
Have you ever used 2 pace BMS on a Victron system? I have this constellation and sometimes only one BMS is displayed in the Victron system, but both are displayed in the VRM portal. This is very strange behavior that I cannot understand. However, the Battery Aggregator sees all BMSs. So the communication seems to work in principle.
Hi Andy, so, I will venture a guess to the heat sinked and non heatsinked fets, the side without the heatsink only switches hard on or hard off, the heatsinked side will probably be the current limiting side which means that the fets are operating in the linear region which means that they will get hot because they are being used like a "resistor",. Just my 2c though, I could be wrong,.
The current limiter is working with a PWM signal, so switching the FETs on and off with high frequency to limit the overall current. They still become warm by doing that. On the RN150 we have another layer of PCB with the current limiter and even this has a small heatsink.
Yeah, very strange...
Yes you’re neighbor is working on a major project. 😂
It's further down the road... imagine living next door though.
For normal usage, based on my recent testing, I'd start balancing at 3.40V and limit charging to 3.43, because I don't see much capacity gain to 3.45. I'd also limit discharge to about 3.13V too for the same reason. You might lose
Yesterday, I had a battery (48V/100Ah) on charge. SOC was at around 39% and solar pushed hard (around 35A). The charge voltage was at 3.42V and the balancer would have kicked in already. That is not great considering the low SOC. At this stage, the balancer will not balance the pack but unbalance it.
Also discharging to 3.13V is too high if you have like 0.5C discharge current (even as a peak).
You may have a very special setup and needs there to run such settings.
@@OffGridGarageAustralia Ah, interesting. I only have the 16 cells at the moment so I guess I'll have to hold off on those settings. But I'm looking at having three times that many paralleled at the cell level so keeping charge and discharge rate below 0.2C
The low side mosfets that switch on and off charge and discharge don’t need cooling because of low rdson.
The current limiter does because it’s effectively a buck converter switching thousands of times a second which generates heat as they move through the millar plane.
They could probably save money and eliminate virtually all of the heat by using ganfets and instead of having separate charge fets use the same for the current limiter.
Or do what I did and use the data from a jkbms to control the amps coming in from the growatt unit dynamically as it reaches full charge since any charge controller already has a buck converter to step down to the battery and can already limit current so no reason to pay for it twice.
Hey! How did you do this, James? I’m interested, I want to do the same in my setup!
@@J0rd40 I hacked the serial coms for the geowatt to provide data to home assistant and same for the jkbmses.
Then you just create automations as necessary that adjusts the charge current of the growatt based on SOC and max cell voltage of the jkbms. Plus, you can emulate float mode etc if you want as well the same way.
Heya, the BMS's are getting better and better
Hi Andy, your are a super great teacher for the BMS Magic!
I’have a question about communication over the two Gobel BMS model. I have 2 RS150 BMS and now i look for building a third batterie with this gobel « PACE » BMS.
Do you know if it’s possible to make them communicate together??
Thanks a lot for all I’have learn with you last two years.

Hi Andy, thanks for all the research you do. I am about to place an order with Gobel Power for 3x GP-SR1-PC200-Standard-HC 280Ah and they have suggested I also get a Battery Home Assistant Add-on Kit.

Thanks Andy 👍
Great vid Andy! A few questions! :)
The 'Pack Fullcharge Voltage' setting (ie. 56v in your case)... Is this what the inverter also uses as its charging voltage if there is of course communication between BMS and inverter? Or does inverter get its charging voltage from a different setting in BMS?
Also, when pack reaches 56v, is this also how the inverter knows to go into absorption mode? Or is absorption voltage set somewhere else in a different parameter?
Then, in a scenario where inverter is NOT communicating with the BMS and it is a basic setup whereby all settings are set manually on the inverter, how does inverter know to go into absorption mode? Will it just use the manually set 'charge voltage' that was set on the inverter? Thanks!
Hi, I pointed out to SOK about the settings on SOK 48/100 batteries that also uses Pace BMS. I changed the settings as you did, but this is the reply from SOK Europe that does not mske any sence to me.
Dear Thomas,
For battery cell overvoltage protect, yes 3.65V is written in spec.
When the battery reach 3.65v, the battery will be charged by constant current and constant voltage, and the constant voltage up to current is 0.05C.
Our battery pack is charged in the current close to 0.2C, and then voltage will reach 3.7V. The charging will be stop.
This is the way call “Standard charge method”, 0.5C constant current charge to 3.65v for cell, then switch to constant voltage charge until charge current declines to 0.05C.
The cell Maximum charge current (continuous) is 100A.
Which means that it can be charged continuously at 100A from SOC 0 until the voltage reaches the cut-off voltage.
There is no problem with charging this current for a short time, and no need to worry that it will damage the battery.
The parameter setting I sent to you is exactly our factory default setting.
We don't know why most of them are not set correctly?
So we suggest you can change all setting to that.
And we are not understanding how this issue is about the old firmware bug in the Pace BMS??
When Current alarm is set to 90 Victron VRM shows 160 for CCL in SOK batterie, when current alarm is sit to 60 it shows 100 in Victron
I think if you can you should test a BYD system. They have good communication with Victron. Just one thing is the BMS will enter sleep mode if communication is lost.
Argh, that's bad. At least these BMS stay awake for 48h before going into sleep mode. As soon as charge comes in or comms start working again, they wake up.
BYD makes HV batteries, I believe? That's not DIY any more though... far to dangerous.
@@OffGridGarageAustralia Yes not ideal, but they do wake as soon as charge comes in but requires the comms to continue charging. BYD does have a low voltage range (48V) I believe they have two models available, a 15KWh and a 5KWh. I may be wrong on this one but I'm sure I read that they support up to 64 batteries on a single system and using the 15KWh batteries would make that almost 1MWh of storage.
Andy I think the interface is from daly (but i could be wrong😊). I been using it for some time now. If you want I can send you the 3d cover for it. But I dont have a way to contact you. 😞
U can change all settings when using daly with there interface. I am using 400A daly with parallel protection using the interface board.
They all look the same but using different interface boards and connectors sometimes. JBD has got them as well.
Great video, very useful! Thank you!
Is it possible to make a top balancing on pace bms? Looks like one of the cells is not fully charged and is not balancing well.
I'm loving the videos as I'm wanting to get my own battery setup.
Can you add into the spreadsheet whether the BMS has passive or active balancers
and what level of current that they will use to balance. Also will they balance one cell or more than one cell at the same time.
I'm wanting to get the 300ah batteries and from earlier videos you said a passive one just is rubbish.
Or should I have a separate active balancer?
thanks and keep up the good work!
Great video. You mentioned changing certain parameters on the Pace BMS e.g. cell I we protection. What are your ideal settings for a 48v (16 cell) lifePo4 please?

Excellent information, thank you Andy. From what I read on internet and what I have seen on your video, it seems our new svolt battery has the pace bms installed. I am trying to balance the cells, cell08 is always lower than the rest, max is 3.371v while others are from 3.456v to 3.485v at 100% charge. I am trying to balance while charging at 10A only, to keep it in charging mode as long as possible as it seems balancing only happens while charging. Not sure if this bms can balance continiously and not only while charging. I do not have bms software yet, so I can not change parameters. I would like to know if difference of 104mV is something to worry about and if balancing will happen within a few weeks of normal daily cycling. Supplier suggested 3.5v bulk and 3.4v float per cell. We have a grid supply situation here in South Africa called load shedding as utility can not supply enough power for everyone, 24/7. Our next power out starts in a few minutes and lasts for 2 hours. This is a daily occurence at present.

Hahaha, I think he's finished now...
@OffGridGarageAustralia really happy for you 😅
Hey Andy, if the master BMS reaches 48V it will report a discharge current limit of 0A to the victron System and this will shutdown all discharge right?
Maybe you can test this?
So it would not be a big problem if the slave BMS`s are set to 40v low voltage
Thx for your videos again and again 🐸
It will request a discharge limit of 0A, that is correct but it will NOT shut down the inverter or MPPTs. It is not a protection setting.
Usually, if there is a hybrid inverter connected it will simply tell the inverter to limit the current drawn from the battery and more from the grid. Until the point where DCL goes to 0 and the inverter uses no battery power and 100% grid power.
With MPPTs, however, this DCL will be ignored as there is only one power source for them to pull energy from (the sun). So in my off-grid setup, DCL may go to 0 but nothing gets shut off.
You will need the NEEEEEEEEEEEEEEEEEEEEEEEEEEEY

I have an Allith power storage 200AH 51.2V with Pace BMS (P16S200A-21382-3.0T). And after the winter and a long low SOC level, I unfortunately always have an OVP error when I load above 99% SOC. I use an SMA Sunny Island 4.4 and have already reduced the charging power from 3300w to 1100w because I want to give the BMS more time for balancing, but unfortunately it doesn't help. Should I just lower the voltage at which a cell should start balancing a little so that balancing starts earlier?
Dear Andy,
any chance to identify the type of the connectors used on the new Pace 200A BMS to connect the balancer to the cells? There are four connectors, two of them are 6 pin and two are 7 pin once. But I don't know the type. I am planning to design an adapter to connect a Neey 4A balancer to the cells without breaking anything.
Hi Andy, do you know, why the Pace BMS has a SleepVoltage of 3,15V?
Below this Voltage, the BMS is going to sleep after 5 minutes.
It doesn’t makes sense.
The BMS goes into low power mode after 24h if no communication, no charge or discharge have occurred, and all cells are under 3.15V. The time can be changed in the settings (Resting Delay, sits on 1440 which is 24h by default)

Hey Andy, does the new BMS turn off charging MOS if the 56V and
Yes, it does turn off charge FETs. In this case it is OK, I think because we have already absorbed by setting the tail current.

12 seconds after posting - is this a record??
I wouldnt be surprised😮

Big 👍
Thank you 👍
One row of mosfet’s probably charging (not cooled) other row discharge (cooled)
Would be the same 200A current in either direction what the BMS can handle. Why would there heat building up in only on direction?
@@OffGridGarageAustralia I suspect that they where thinking that you may not be charging all day long at 200 amps, maybe discharging all day long at 200 amps seems moor logical, they could be just more efficient fet’s
Hi andy... do you know of a good charger that will do 100 amps at 29.2 ?
Yes, I have one on my website, have a look at the high power variable power supply. They make them with 30V and 100A as well. They work great for charging. I use my 60V 20A all the time for that purpose. Very good quality but not cheap though.

Am i doing something wrong or does the gobel link just not have this MBS for sale anymore?
is it able to communicate with the venous OS on raspberry pi, if yes how did you connected can to pi(is it via any USB converter specified in the other video of JK and Daly communication). Thanks
Can pace bms works parallel with daly bms
Pace connect can or rs485 (Pylon) to Deye is work ?
Am use not ok
:hi Andy I’ve just purchased a pc200 pace bms con you please give me a link to download the software for this bms please
They took that off the website. only a 150 now
Can anyone tell me if there is a managed bms that can talk to a selectronic inverter. I contacted Batrium no luck there. Has anyone have experience with the selectronic inverter? Thanks.
Does the Pace BMS support connection of the 51V batteries banks in Series like having a HV pack by having multiple BMS connected together ?
No idea, you have to check the specs and manual of the BMS for such a special setup. If in any doubt, I would contact Gobel directly and ask this question.
51V batteries in series is not DIY any more.
hi Andy,
i have recieved a pace bms version P16S200A-21587 -2.02 i checked your spreadsheet...
i noticed in this version the CVL is not taken from the Pack FullCharge voltage but from the Pack OV Alarm setting ..
any one here noticed the same? and how to setup the config now with this in mind
Andy, something you could check ?
regards from wet/cold Netherlands
@MrRschutte I have a Victron EasySolar II GX 48/3000 with 2x Micromall batteries each with a Pace?? BMS CY-IH001-B100LT48-V1.0.0 and windows software Family-BMS v1.1.635-38. In my case the CVL as shown in the Victron console is 55.7 V and nowhere in the BMS software UI is that number, nor is it anywhere in the exported settings file.
What exactly does the "Dry?" Contacts, please?
They usually close a relay contact when something happens. For example, the close one contact if there is an alarm and close the other contact when there is a protection status. This can then trigger external mechanics, like turn on an alarm light, a siren or turn on a charger/generator.
They change the functions from FW to FW and it is really annoying that the user cannot select what function a relay contact should have.
@@OffGridGarageAustralia Thanks !!!!
You like the pace BMS better than the Jk bms
Different use cases for each. There will be anew JK soon, so... ;)
@@OffGridGarageAustralia can’t wait for the new Jk BMS.
Hello Andy, thanks for all your great videos!!
One question about this one - when you look at the BMS Canbus screen on the Cerbo is shows (@19:04) “ERROR- ACTIVE” as the state ? Even after you set the dip switches - it stays the same. Is this normal ? I have the same on my Cerbo.
Also on your “details” for the BMS you get cell status “high cell- low cell” is this something you added as mine does not show this from a different PACE BMS.
Thanks
Kia ora @Over_50s_DIY_Vanlife, I have the same "ERROR-ACTIVE" on my Venus GX device console. I had it before the batteries were connected and still now.
@@grahamharris1985 my system seems to work well but I did lose all the SOC from the batteries as I had a very small current (0.4 amp) which the BMS didn’t pick up so I now have added a Shunt as my battery monitor
You would think with all the BMS’s and inverters on the market that they would standardize the communication. Basic settings that all BMS’ use would be the same along with a battery ID for each BMS/Battery. This way if you don’t know what kind the BMS is just pick Basic/Standard in the list. IF an inverter has a special feature that is not common then you would need to pick that inverter to see those advanced features that are built on top of the already agreed on basic feature and communication. It’s not rocket science, even governments can force this standard saying that without it can be a safety hazard or possible fire risk.
Hi, can you help me with the password for pbms tools software? Isn't "123456" , i'm from Italy😉
Can you reset the PACE no. of cycles to 0?
Do u have a link for the bms software in laptop?
I think your neighbour is taking down some trees to circumvent shadowing on his solar panels? (joke!)
Back to the topic;
I assume all those Pace BMS all have the same firmware? And also support bluetooth?
As for why not all Mosfets are having a huge heatsink pre-installed, I would assume those without a heatsink are used for the balancing currents (max 5 amps) and therefore wouldn't get that hot. On the other hand, the way the board is mounted, could it not be that those Mosfets without heatsinks are touching the inside of your battery-case and use your case as a passive heatsink?
As for the switch, I like the new switch better as you have a far better visible que that it is on or off, with the pushbutton it is harder to see, I believe.
I agree, M5 instead of M6 (or better: M8) is not really a good choice and they should have included the bus-bar, makes it a more complete solution.
The good news is there are "coffee-machine" switches in a round version. Even with a LED and different colours.

Ist da das pace BMS verbaut ?
Ich möchte jedes pack extra auslesen mit victron cerbo und NodeRed geht das ?
Any chance the "Export Datas" tab would send or allow the export of parameters from the master to the slaves while still connected as a parallel pack? Realizing the capacity differences will still force individuals to be programmed separately, would be nice to know if the capability exists in case one were to have multiple packs of the same capacity cells.
Yeah, I think this is possible. You still have to connect to every single machine though, I think. I will test it...
It's not possible, you have to connect to each port to affect the settings, you can only get specs, (SOC, Current and voltage) over the rs485 daisychain, I have 2 packs with the same style BMS's and software, I have tried, a massive PITA, you can only change the settings of the pack you are physically connected to.
@@GapRecordingsNamibia correct, i have 10 pace bms'es in parallel at one site. Only a physical connection works for programing.
So is the BMS balancing not working? How many amps is it supposed to support for balancing?
The balancer is only 50mA passive. It may work but won't balance any larger battery cells. Active balancing is needed.
Yeah, some people may be lucky and have very well matched cells and the 50mA could be enough but over time, when they age, they tend to drift more and more and the balance won't cope any more.
So can this bms be used in "starting" lithium battery? if I understand correctly full cutoff is not hard and alternator can adapt to full pack and bms hard cutoff that burns alternator will not occur?
If not, how those start lithium bms work?
As far as I know, when using an alternator, you would need some sort of DC-DC converter to charge your Lithium battery.
Does anybody know, which type of 4A active Balancer (with Bluetooth) Gobelpower is using in their batteries?
Heltec 5A or 4A active balancer
