Hello, I have a question, I purchased a NOCO 15000 for a 100amp hr 12 volt battle born. When it's charging, I take out my voltmeter and get a reading of 13.6 to 13.7 I don't read the 14.4 volts. Should it be showing 14.4 or at the level of the battery and that's why it's 13.6 volts?
Having Lithium batteries myself (Battle born, 4 of them) my OEM charger/converter in my motorhome, charges the batteries just fine. The only time it will take them to 14.4v - 14.6v is when it goes into a 'bulk' phase (or some call it the absorption phase) , as the previous phase is the 'float' phase. The batteries don't usually hold in the 14+ phase, as they go into a 'rest phase' staying around the 13.7V. I've had my Battle Born batteries for about 3 years, with no issues whatsoever. I did add a Victron 'shunt' allowing me to use an app on my iPhone, so I can see how the batteries are doing, from inside our RV. We have a residential fridge, so this obviously lowers the batteries down overnight, to where I use my generator to bring them back up. Not all campsites, RV parks have shore power, so having Lithium has helped to where I don't have to worry about the batteries going down below their 50% usage, to where it might harm a regular flooded lead-acid batteries, but not a Lithium.
Hi I have same charger g7200 and try to charge Renogy 12v 100ah lifePO4 battery under "lithium" mode, but it only charges up to 48-50% and 100% light comes on? Is it bvecause of the BMS? Should I use different charge mode?
These type of chargers use a generic lithium charging profile that may not be an exact match to the manufacturer's recommended settings. You may want to do some research or contact Renogy to find the settings for best charging for that model battery. The Noco may be off by a few tenths of a volt and that may be enough to throw off the charging of the battery.
Any luck with your g7200? i have the exact charger and will be purchasing the exact battery. Was hoping there wouldn't be an issue, but the documentation on the Noco says it charges at 14.2v in lithium mode and the documentation on the Renogy LifePO4 stipulates it requires 14.4v.
Thank you for taking the time to make this review. I often wonder what Chip is used for the Charging Profiles? Is it the same Chip used in CTEK products? Or other similar type chargers quoting very similar specs? Do their share common algorithms? I ask this, because the 3.5A Noco or 5A CTEK both offer Small and Larger Battery selection. Where as the 7.2A Noco or 7A CTEK do not offer a selection between Battery Sizes
Good question. I don't know the answer, unfortunately. Maybe if I can find the time and funds I can take two of them apart and compare the inside electronics.
Ive done it. The parts used and build quality of the CTEK is far superior than the Noco. Noco is a very cheaply built unit, with a basic 1 layer board, cheap caps, poor isolation from the 110-240v side. It is very simple compared to the CTEK build. Hence the price difference i guess. As for the chip sets and algorithms, im not sure
Yeah I would be curious to see what microcontrollers they use. The Noco might overcome some questionable build quality with some awesome programming but probably not.
thanks for the video very informal (still looking at more) just wanted to ask do you think this will be able to charge / cycle / maintain my 2017 BMW M3 that has a lithium battery supposedly its recommended for heavy coding / programming a 50amp charger and only ones I can find are the standard car chargers one to provide such power. Cheers
I can't say for sure. I would be surprised if this charger doesn't work with your battery, though. I know the ctek one does as I did a quick search and people in the forums are saying it works great.
So would this work for LiPo battery (2-4 cell) used in the Radio Control applications... ie 2 cell, 7.4v, 1500mAh, 15c. Trying to “revive” a dead cell, and I’ve heard this charger possibly has that capability.
I can't say for sure. It has a fairly generic charging setting for a broad range of lithium chemistries but may not be able to revive anything. Sorry I can't be more helpful on that. If it were individual cells I could recommend a good tool but not for a pack like that.
It can do both. Did you see the video where I started the car with it? You just can't leave it in a car because a car alternator cannot charge lithium and it would damage the battery.
I was talking about the material for the battery. Can one lithium iron phosphate battery do 3 things (start a car, deep cycle, and wait for a power outage)? Is it like a lead acid battery where the anode/cathode need to be thicker than usual to handle deep cycling?
Of course and many do. I mean, look at all the Lipo Car Starters being sold. Not mention those people that have fitted a LifePo4 battery in their Bike or Car or 4WD.
Actually they can be used under the hood of a car if properly insulted from the heat. Most name brand cells can handle up to 140 degrees Fahrenheit before they become unstable. I do competition car audio and I run a 40ah lithium battery under the hood of my car along side 6 banks of maxwell boostcaps an I charge between 16 and 16.8 volts. My particular battery uses four 18650s in series so that's why I can charge to 16.8 safely, each shell can be charged to 4.2 volts.
Est-ce du plomb? Ou du lithium ? Gardez à l’esprit que ce chargeur ne peut produire que 7,2 A, il faudrait donc presque une journée complète à votre batterie pour se charger complètement à partir de 0.
The battery isn't commercially available. It was put together for me as a favor by Mike at Lithium Storage in Utah. The smallest they sell I believe is 100Ah. www.lithiumstorage.com/index.php/en/
Sorry you are right, i missed it. I have 22S18P 18650PF ebike pack over a year now without any BMS and still 0.001v accuracy balanced. Seems that quality 18650 cells not need cell level BMS at all. But Lifepo4 needs cell level balancing. Excited to see upcoming Lithium videos :)
I was told by the supplier that a 4S configuration for LiFePO4 does not need balancing. I don't know whether that will turn out to be true or not but I will continue to measure individual cell voltages periodically as I charge and discharge this battery. Thanks for the support!
It will charge the battery but it most likely will not be anywhere near full. 14.2V is too low for most LFP batteries. They need 14.4-14.6V and some time to balance the cells. My NOCO that you see in this video does not fully charge my LFP batteries. So you can use it in a pinch (it won't hurt the batteries) but for your everyday charger for a lithium battery it is not the best choice. If you are interested, I have several lithium battery chargers from MillerTech on my web store that are excellent: store.ldsreliance.com/collections/other
i have a 100w 12v solar panel on the roof of my van that puts out about 4a. I'm thinking about getting a 50AH Lithium auxiliary battery to run a 12v 3a fridge during the day and 2a 12v fan at night, but I would also like to charge that battery while I'm driving without manual switches. Any way to do that?
Thank you for this video. I am trying it on my new lithium Batteries and it's not reading anything. Goes only to 10.6 V and not scrolling through the settings or showing the amount of charge
So your Lion batteries are only 10.6V? Or where are you getting that number? The NOCO may not be able to recognize that there is a battery attached at such a low voltage.
@@LDSreliance Ok I am sorry I have not been more specific. Its a set of Lion Energy Safary UT1300 12V 105Ah Lithium Iron Phosphate (LiFePO4) Battery. .
LiFePO4 is Lithium Ion. But yes there are slight differences in charging profiles between the two chemistries but that is also the case with lead acid. The settings are close enough to charge the battery without harming it, even though it may not reach 100% SoC every time. It will be close enough for most.
@@LDSreliance Do you think chargers with LiFe and LiPo can charge LiFePo4, because these companies are not putting LiFePo4 on the specifications and other people are charging 18650 that are smaller LiFePo4. I can not wait any longer for them to start stating in their specifications. ISDT says no, other people say yes they can do LiFePo4. If I want a massive battery pack I want to know it will be charged, balanced and discharged optimally for long life. The LiFePo4 commercial chargers are a bit slow in reaching the mainstream market. I can not get all in one on Banggood.
The BMS takes care of the balancing. So that is not a function that you should be worried about with a charger. Maybe look in the documentation/specifications and see if the charging profile is cc/cv (constant current constant voltage). If so, then it can definitely handle LiFePO4. Also, if the charger is programmable you should be able to put in your own settings. I do sell chargers for this application, though. If you want to email me I can send you a quote. ldsreliance@gmail.com
LDSreliance, to prolong lithium it’s said that charging to 100% isn’t ideal, but about a 30% discharge and 80% charge will triple the life of a lithium.
@@LDSreliance was reading in forums that the Nocos didn’t charge the lifepo4 batteries all the way up.. which is why I didn’t buy the Noco Genius gen5x2 to charge my 12v 100ah battery - also can’t find anywhere on the noco website about specifically charging lifepo4 batteries except lithium’s instead
It is a generic lithium charging profile so it isn't perfect. Ideally, you want to get a charger with specific parameters designed for your battery. But if you don't have anything else this will do the job just fine. It doesn't hurt the battery not to be fully topped off. Obviously you lose a little bit of performance since it isn't 100% charged but not much. If you are going to buy a charger for a LiFePO4 battery do not buy a NOCO. But if you already have one you can use it just fine.
I am trying to use a G7200 to charge a new 12v lithium battery (from lithiumbatterycompany.com), and the Genius charger seems to not like charging batteries that have too low of voltage. These batteries ship at around 3volts... so when the genius tries to charge it, it stops after a few seconds. This is how it looks: ruclips.net/video/a4TYjpby1pU/видео.html (it goes into standby because of the low voltage). Is there any way to force the charger to charge when the battery has a low charge?
No, unfortunately. I have heard of this problem before. Do you have another battery that has a charge that you can attach in parallel and try charging that way? That might help it jump start.
I think the challenge is that some lithium batteries have a build in BMS that appears to prevent charging if the charger does not limit current and voltage. The Noco Genuis chargers will go to "standby" if the battery is too low, so these chargers are not appropriate for charging in this case. While this isn't a problemwith lead acid batteries, since you can just use a regular car charger, I'm a bit careful with the lithium since it was $180 and I don't want to damage it :)
The BMS will prevent damage. You can try charging the battery on a lead acid setting and see if it works. I have had a customer do that before and it worked.
You were right. I put the lithium on a regular (and heavy) 12v car charger.. connected it a couple times for about 20 to 30 seconds.. brought it from 4.4v to around 8v... and then connected the G7200... and off it went charging it.
OK, not that I don't believe you but your opinion won't really hold any weight unless you provide some basis for it. Do they not last long? Are they overpriced? Do the charging profiles not do what they say they will do? Are they not safe?
Noco chargers are actually very good chargers. I have the G26000 and I've used it for lithium, AGM, an regular lead acid batteries and had nothing but good experiences with it. I've brought several lead acid batteries back from the dead and I was even able to charge a large bank of capacitors with it and had no issues.
