Hello, I recently acquired 4 - 3.2v 280amp (EVE), with overkill BMS. I also got NOCO Genius 10amp 12v battery charger.
The overkill setup is default. The only changes I put in is the capacity (280amp), and cycle capacity(224amp). I don't understand cycle capacity. I don't want the battery continue to discharge when it depletes 75-79 percent of the battery. So It should be either at 70-80amp or 224amp?
I checked each battery and it was .001 voltage difference. I set it in series, then use 12v charger. After trying to get it charged couple times, it won't get to 90 percent. It shuts down. Because the voltage in each batter differ greatly. One could go to 3.45v while others are sitting idle at 3.2v.
I believe that NCO 10amp 12v battery charger has it's own voltage to charge the battery, and it's fighting against the BMS voltage limitations. Also, it isn't charging correctly from what I can understand. It dumps into cell 2 or cell 3 instead of primary cell? It doesn't make any sense. It also tells me that it is full, but it is not. I think it is sitting around 40-50 percent? These are the results. Is there something wrong with my setup? or is it the charger that's causing issues that I should return the charger, and get a better charger?
Also, I decided to do subtle discharge to see how it is functioning. And it's not doing it right either. One of the battery cell voltage would be greatly lower, while one other cell is greatly higher.
Thoughts?
