Hi everybody,
I recently built a 12v lifepo4 battery using 3.2v cells that I purchased from Ali Express. It has a Daly BMS and is charged from a Renogy DCDC charger with MTP from my truck. My main usage is just powering my electric cooler while camping/off-roading. Recently I noticed the my cells weren’t charging from one bad cell and believe it may have cracked while off-roading. There was an oily substance at the bottom of my battery box and the “bad cell” had a voltage of 0.6v. I noticed that my bus bars look really corroded but still decided to order a new cell. After waiting 3 months for a replacement from Ali they sent me a refund and said they never had the replacement in the first place. I noticed that there are 3.2v 100AH cells from Lynx on Amazon can I purchase and wire one of these up in my original pack without any major problems? What is the biggest drawback of not using matched cells? The bummer is that I only spent $200 for all 4 cells originally and the Lynx is $125 and 20 less amp hours. Are the typical blue 3.2v cells even durable enough for moderate off-roading if stored in the cab or should I be looking at Caleb cells or even a sealed AGM?
