I have a 72v 35ah 20s battery pack and ANT BMS my question is why it is not charging to full max charge it ever did was 84%, around 80v. Cells were new and are balanced. Should i set the UnitOverProtect to 4.35 like in your video? Thanks. I would appreciate response 🙏
@@Daniel-zy8ur connect your phone to the ANT bms and start screen recording. Slowly Scroll each page, top to bottom, starting with the main page then go to parameters tab and open each page, scroll top bottom. Starting from FastSetting and each one down until PackParameters. Take your time scrolling so I can see the setting and so its more than 1 minute long so its not a short (so i can use timestamps). Upload “not for kids”. Because I don’t have the kids app and can’t comment if its for kids. Then come back and let me know its uploaded and PUBLIC and i will come check it out and tell you what is wrong with it.
0:00 Default settings always is for max series, 16s for the 7s-16s version. 0:10 its a hot mess right now because only 13s connected but its set for 16s default. 0:30 go to FastSettings and set correct series and AH, clicking “settings” afterwards. Then click battery chemistry type and then hit “SAVE” 0:45 first use you enter password 123456789abc 0:52 now we see everything looks ok now. 1:18 default balance settings will work for most batteries, but we can set them for better monitoring. 1:28 UnitDiffOffV tells the BMS when to stop balancing. It can be set for 0.000v difference. 1:50 it will not automatically balance unless 3 conditions exist. 2:18 ChargingUnitBalStartV is the minimum voltage before autobalance can automatically start. Let’s set it to 3.8v for now. 2:30 once battery voltage, voltage differential, and charge current conditions are met, 60 seconds later it will automatically begin balancing 3:26 autobalance has been initiated. The ANT waits to allow the cells time to get to resting voltage. 3:35 the ANT uses passive balancing, which is sufficient for a healthy battery properly matched. 3:50 the green cell groups are being bleed through load resistors to bring them down to match the lowest cell. 4:00 some BMS use active balance, which transfers energy from the higher cells, into a capacitor, then dumps it into the lower cells. 4:10 If your battery is 💩 then you need an Active Balancer. But a good battery with passive balance is better. 4:19 we do not want autobalance starting on its own or it will mask any problems. So I set start Diff to 0.500v 4:58 UnitBalanceLimitV is an overflow setting. Any cell higher will bleed, so we set that high so it doesn’t ever bleed. 5:28 we will manually stop auto balance. 5:39 no more green lights. Balance stopped 5:43 now we manually start autobalance session 5:48 now it’s balancing down to 0.000v differential as long as battery is not charged or discharged, which interrupts it. 6:20 Voltage parameters are set according to your needs and your charger. It can be set 3.800v-4.350v max cell voltage. 3.8v for charging to storage voltage only. 6:58 recover voltage should be set slightly lower so charging can resume after you let it balance. But not so high it allows rhe charger to cycle on and off rapidly. 7:20 temps parameters can be set if you have the temp probes connected. Defaults cell overtemp is 60c but can be set 40c-80c 7:36 cold weather users need to set low temp settings for charging also according to cell datasheet 8:52 the current limits have a lot of flexibility so stay within reasonable amps and time limits. 9:03 this is a 180a BMS but I can set it for 600a. Not good because the temperature protection might not react in time. 9:12 these should be set mainly based on battery characteristics, DC power cable size, BMS rating 11:18 right now it thinks it has 71% SOC, 11:35 remaining AH just tells the BMS what your AH is initially, after that its not used. Let’s set it to 5ah. 11:43 it changes to 5AH (33%) then automatically calculates it from the SOC table and corrects it to 52% 12:18 these are the SOC calibration table. You can change these to match your cells and climate. 12:22 SOC Method 1 lets it automatically use the SOC table. SOC2 just uses electrons in minus electrons out 13:00 AH set to 0 so SOC os 0 and not automatically adjusting 13:28 AH set to 5 so SOC 33% (of the 15AH total capacity i entered in Fast Settings) 15:00 i think one of the SOC methods allows it to correct with a longer time delay. 18:37 systems parameters allows you to set when the bluetooth sleeps, and what will wake it up. 18:49 NoCurSleepTime is 1800 seconds default, but you can set it to 0 and it will stay awake always. 19:27 MOSFET overtemp can be set 40c to 85C. Colder gives more protection, but it can also shut down under normal riding if too low. 19:51 charge temp can be set lower. 45c is recommended. Release at 40C. 20:33 Balance charge current blocks balancing if over this limit. You don’t want to balance a difference caused by surge. 20:57 should be set to whatever current causes enough voltage surge to create a difference. About 10% of the AH should be ok.
My battery 72v 40ah 20s sat for a long time not charging or being used. Now battery won't charge. Any ideas? They had me change to lifep04 and change lv2unitlowvrecover to 2.1. Still won't charge.
@@jungbae3 can you make a screenrecording of the ANT app and do a slow scroll from top to bottom of the main page, then go to Vparams and do a slow scroll top to bottom, then upload it to your channel and let me know so I can go take a look. Then I can give some recommendations.
@ , does your battery have an ANT bms? what happens when you plug in the charger? Does the battery connector read any voltage with a multimeter? If you can connect your phone to the BMS, you can make a screenrecording of the app and scroll through each page, then upload it to your channel and come back and let me know so I can check it out.
T2 is 77c and so are the other 3? Or the other 3 are showing the same but cooler temperature? Is this with the battery at rest or during riding? Who made the battery? Where was T2 temp sensor placed?
The basic setup is the same: Go to FastSettings: Enter 50ah click “settings”. Enter 20s, click “settings” Click “Li-ion”, then click “SAVE” at the top. This will set all the basic default voltage settings. For current settings the default is the maximum the ANT is rated for, but these should be set to suit your battery cells, buses, and DC cables to the controller, whichever is the weakest link. There are 4 current zones estimated in current settings DisCHGOverCurProtect sets the upper limit of continuous amps, meaning the amps you can run the battery continuously from full charge to empty without it getting hot, or the wires getting hot. 0a to this setting is zone 1. Zone 2 is anything over zone 1 up to Lv2 DisCHGOCP, and the time delay for DisCHGOverCurProtectDelay is the number of seconds you allow in zone 2. Zone 3 is anything over zone 2 up to the short circuit protection. The lvl2DisCHGOCPD sets the milliseconds you allow in zone 3. Zone 4 is anything over short circuit protection and the delay is in micro seconds.. So lets say your pack is 3C continuous, 6C peak. Your settings would be: 150a 30s 300a 1000 milliseconds 500a 1200 microseconds Then you make sure your controller settings don’t ask more than this.
@@jeffersonnatanawan4083, if you are getting a discharge mosfet failure then your BMS might be fried. Can you tell me what you were doing to the BMS before this error occurred? I have only heard of this happening when the BMS is off and someone connects the charger in reverse polarity. With the BMS off, the discharge MOSFET are off, and the charger can fry them. But if the BMS is on, most likely it will just fry the charger. If you can tell me what you were doing just before it happened, I can probably tell you why it broke. If you remove the BMS and open it you will probably see burned MOSFETS. These can possibly be replaced but the ANT BMS is very inexpensive so buying a new one is probably better. Was it worked before? I know you asked 3 months ago how to set it.
@@jeffersonnatanawan4083 , you need to replace the BMS but first try to tell me what you did to break it so it can be avoided next time. What were you doing to the battery just before it stopped working?

To see what the battery can take you can try to screenrecord the ANT main screen scrolled to boxes 4-7 , which has all the important information. With that I can tell you what settings would be best. The Votol settings and the ANT settings should be compatible. The Votol settings should always be the to reduce or stop current before the ANT needs to.
