Long 100ah AGM batteries


Recommended Posts



I got a bunch of 100ah Long branded AGM batteries.

I have connected them in series to a 48V Axpert 5K.

I'm not sure if this is normal, but please see attached readings that I get from the batteries - is it normal for the batteries to be so different from each other.

Way one - batteries in order from 1 to 4

Way two - swapped batteries 1 and 4 around and re-measured


Thanks in advance for the help!
