Hi all, I've had this 72v battery for a couple of years now and it goes great
https://em3ev.com/shop/em3ev-72v-20s10p-rectangle-battery-pack-24-5ah-29-5ah/
However about a year ago it stopped balance charging and just continues past the 84v fully charged point. I've tested the charger with a multimeter and it says its doing 83.5v which seems normal? It's just a chinese charger.
Is it the bms that determines when to start balancing and tell the charger to stop? should I look into a better charger first?
The battery and bike still go great but I just don't full charge anymore since I have to babysit it and don't know if anything is balanced now.
Cheers
