Thanks for that info, so there was an emergency the other week and I had to use the LiPo battery bank to run a split AC unit max amp draw hovers around 20-25 amps at around 1K watts give or take 200 watts during startup then hovers around 200-500 watts at 7-9 amps once it cools down, I got a total of around 10Kw+ out of the batteries, they are Chins 12v 100ah actually capacity test shows 110ah each, times 6 according to the Victron's smart shunt, once drained I charged them up with a Victron's charge controller, once charged I check the voltages and found that most of the batteries were not charged to the parameters entered on the charge controller and voltages range from 13.52v to 13.72v per battery, I let the batteries sit for an hour and checked the voltages again and basically got the same results. What could be causing this? Don't the BMS in each battery manages the charging voltages per battery? If so, why the discrepancy? I checked every battery when I got them and they checked exactly according to specs. I uploaded a picture of the setup, all cables are 2AWG pure copper, all lugs were crimped with hydraulic crimper also copper, all cables measure the same length maybe a very small variance. The battery to bussbar cables are 2AWG by 36 inches, the cables from the Inverter to the bussbar are 2AWG by 18 inches long, resistance on all the cables was checked and is 0 in my meters, from one end to the other and no voltage drop. I have contacted Chins to see if they can give me some feedback on this. The picture got cropped when I uploaded but there are 2 breakers at the end of each string both terminals + and - are hooked up to the proper breaker at the end of the string, from the + breaker the + cable goes to the + bussbar, from the - breaker the - cable goes to the negative bussbar. not sure if I explained this correctly. All cables are secured and maintain equal size and length. The maximum amperage this bank is used for is around 25-50 amps since I have another bank for small appliances such as lights, refrigerators and microwaves. How precise are these BMSs on these batteries? Hopefully I can get some ideas on how to set this up so the batteries can charge correctly in the near future.
