Hi all, I searched, I promise and couldn’t fit the info I need. I have a 120ah lifepo4 battery I built from prismatic cells in my van. It charges via a small solar panel permanently mounted and the alternator when I am driving. Recently I haven’t been driving much and my always-on fridge is...
Hey everyone. I have some new cells I am trying to top balance and it is taking longer than I think it should. I first wired them up I series and charged them up before putting them in parallel and balancing.
I set the power supply to 3.65 volts and have been running it for a couple of days...
I still need to diagnose what I did wrong, but I ruined one of the cells in my 12 v 120 Ah pack (overcharged, vent blown, bad smell). What I did wrong is a different (shameful) discussion. My question is - what do I do with the other three cells? Is it feasible to buy just one cell to replace...
I am getting strange (and wrong) readings from my BMS while the alternator is charging. The BMS reports cell 4 is at a very high voltage (like that 3.8) when the alternator is charging the system. I confirmed with my Fluke voltmeter that the actual actual voltage is closer to 3.5. Readings are...
I made a bad mistake overnight and ruined my battery that is installed in my van. See photos. I need advice on how to safely remove these cells. They are completely wedged in since they are so far swollen. Will the swelling go down? How long will that take? It has only been a couple hours...
Acknowledging that I am a noob to all of this.
Recently received my four 120ah Lifepo4 cells from Alibaba and BMS - same as sold by Overkill solar. The cells look fine and measured individually ~3.27 each. I attached the BMS but it is telling me a very different story. Pretty sure I have...
Hi all,
I built a 120Ah battery using the Overkill Solar BMS (also sold in many flavors from Alibaba) and installed in my camper van. Once the battery is at 100% and the van still running (alternator charging) the "cell over voltage" protection from the BMS frequently kicks in and stops...
Tried to keep the battery setup in my van simple with just the cells, BMS, and electronic bits but am really dissatisfied with monitoring the battery through the bluetooth from the BMS. The SOC seems to be all over the place and a few other annoyances. Can someone point me to a product or...
I’d like to test the voltage of the individual cells in my LIFEPO4 12v pack and compare to the reading of my BMS. Really tired of disassembling the bus bars and balance leads. Will I still get accurate readings for individual cells if I keep them assembled? Assuming no, but wanted to check with...
