One of the last things I purchased from the Lockheed surplus auction sale in Lancaster was a 115 pound transformer with secondary windings that look to be around 12 AWG. Center tapped transformer with six Hx connections.
It took me several hours but I managed to configure it as close to 2.666 rectified DC output as I could.
This is my inner cell balancer for my 12-cell series parallel bank. The weak sister cell out of 24 has been disconnected from it's sister by means of a four 3/8" bolt plate so it is isolated.
Individual cell management is about as thorough as a person can get.
An IR pistol even the Harbor Fright model is useful to scan cells in a jar and detect a warmer cell.
It's less damaging to slightly overcharge an absorbed glass mat battery than it is to undercharge it chronically. This does not give license to go hog wild with the charging but may lend weight to deciding where to compromise.
