I still have a couple of Lee's battery monitor kits - circuit boards with relays so that each battery can be monitored and charged individually if needed. It's a manual system by itself but it's designed to interface with a simple processor board for automated control. He has all plans and details on line. I have two sets of three boards (8 relays each for 24 total). One set is assembled and one is not (needs about 8 hours of soldering). These are upgraded kits with better quality relays (20 amp I think).
