Ant BMS balancing problem

[arvatadryan]

Hi there
I build for myself a Surron battery 72v 57ah 20s12p
After I connected the ant bms I started to balance and it did till 0.004 and then stopped
Now it doesn’t wanna start balancing anymore ,it is normal?

I only know the old ANT BMS version. There you could set the threshold for start balancing and you could seperatly set the Cell difference in mV .
Now I use a JK-active BMS and set it to balance above 4,1V and more than 5mV difference.

If you built your own battery then it wouldn't be too hard for you to trash your Battery Murdering System and re connect the sensing wires to RC balancing plugs and then use cheap RC chargers to balance your battery once or twice a year. I've used this primitive system successfully for more than a decade. Need to keep track of your battery Voltage while on your rides though. I use a CA.

Show your settings on the Ant. The gear shaped icon , you are probably running with what is ships with.
I too only know the Old Ant app/software
Later floyd

I found where I can set the difference in settings
What would be an optimal difference between the cells ?

I set mine to 5mV difference. Other BMS are set to 2mV or even up to 10mV.

Okay, now I feel very comfortable asking this "publicly" (because oh please, this is a joke, right?): what on Earth is going on around this forum? It is SO WEIRD sometimes. That's a cute joke, but seriously, I think he meant "battery MANAGEMENT system."

No?

You read it right. I think a BMS causes more trouble than they are worth. I just don't trust them. However it you are clueless on what is happening with your battery then one might be useful. Just never for me.
