This bank is set-up as 3 X 24V batteries connected in parallel. Each battery positive and negative is individually connected to the shunt. Those 3 batteries were all installed at the same time and each have their own internal BMS. Lengths of cable between batteries and shunt are all equal.
I have had issues where 1 or 2 of the batteries go inactive after a while, when that happens the 3rd battery remains active with the charge/discharge load. In a discharge scenario when I see this issue, the voltage on the active battery starts going down, while the 1 or 2 inactive batteries maintain their higher voltage, they are like sitting there in standby mode. I know this because I've been monitoring the current flowing in/out of the individual batteries, so easy to see when a battery goes inactive, all of the charge/discharge current going through the active battery/es.
Questions -- Would a battery balancer help keep those 3 batteries active and balanced? If not, any other ideas on how to fix this?
Thanks
