Hi Jay, if this is the LA AGM thin plate, I tried to look into this a few years ago. Being AGM, they have a recombination feature; when overcharged, they recombine the H2 O2, thus self-balancing, just like the top balance in LiFe. The caution is not to charge too fast in absorb mode. I decided n

Hello Chris, LA batteries do not have a BMS that can block current flow to a series group of cells. Balancers are not likely needed but may benefit an aging battery bank. A long enough charge time (CV) on a healthy bank will fully charge all cells even though some cells will experience high vol

Jay, I started recommending the Victron battery balancer for all series and series/parallel Li battery banks. It has eliminated trouble in some problematic systems. If you reach a cell over-voltage in the Kilovault BMS, it will block current flow, preventing the other series batteries from char

Hi All I’m wondering what the thoughts are on using or not balancers for 2 12v lithium in series for 24v system. The batteries don’t have any series communication. Kilovault if that matters. Not my design. It would seem to be a good idea, with victron having a good one. Thanks in advance
