I wanted to make a point regarding all BMS with an included SSR switch. Both Active Ballancing BMS and AntBMS work on the same principle. Conclusion was that I do not believe overcurrent was the culprit. Looking at the photos you made of the BMS PCB, I do not see clearly the SSR. There are some...

I arrived on this thread because I wanted to buy an active equalizer, to parallel it to my BMS. I was curious if is worth it to change the BMS also (to have only one instead of 2 sets if wires to the cells) but that is clearly out of the question now. I will buy the 2A, RS485, Active EQ. No...

My thought exactly. One bms is not communicating with another, so there is no point to buy this custom bms when you can just get the battery voltage close to 50-100mV and them connect.

Hello. I am using AntBMS for 4 years now. I have the 300A version. I charge daily with 60-80A my battery and nothing happened, although the specs say the maximum charge current is 50A. I can't explain why they would say that. I opened a lot of these BMS units from AntBMS (all bought from IC...

Yes, that is correct. If the BMS is in LVD mode, the discharge direction Mosfets are open and the charging current goes through the body diodes. But you also have to keep in mind that once current starts flowing into the battery, the voltage will rise and the LVD condition will not be valid...

The current flow will not be that great in that case, do not worry. I have different chemistry batteries in parallel and the currents flowing are insignificant, compared to the high load ones.

From what I see, the connection wires to cell 13-14 are not good connected. Either that or the 2 voltage sensors are dead. Still, I would first check the wiring. If is really broken there, you can still use it with batteries of up to 12 cells.

Then is broken. At least you can use it above 12s. I have the 2A balancer with RS485 and that is enough to command the inverter/charger to shut down if there is a problem. I don't use a BMS anymore.
