I've got 16s LiFePo4 (48v) that I built using a chargery BMS.
I also thought I'd try out an active balancer. I picked up a 2a Chinese one and after some work tracked down the software.
My issue is the BMS and the AB are showing different numbers. The AB consistently reads .4v lower (total, not per cell).
Also the AB balanced it within 5mv but the BMS thinks it's off by 180mv.
I checked the voltage with my meter and it's matching the AB not the chargery.
I'm using the factory shunt so not sure what the deal is if I should calibrate the chargery or what.
I'll keep messing with the AB and post on it individually.
