Well, as I'm about to upgrade the BMS in my Truck, the old BMS (used on Leaf
modules) is going to be for sale.
Note that this is my own design. (6th design over the past 12 years)
Good points:
Each board can handle 3 Leaf Modules (6 regulators) configured as
either series or parallel groups.
Top balancing, up to 200ma or so of balancing current.
Load is hi power LED's, so it's REALLY EASY to tell when it's
balancing! (clear covers on my boxes will light up the whole shop!)
Has over voltage and under voltage detection.
Simple single wire/signal output. (+12v is good, anything else is bad.)
I have a simple interface board to connect it to a buzzer and relay to
shut off a charger.
Boards are designed to daisy chain for easy installation.
Bad points of the old units: (that the new units that I'm about to try, should
fix.)
I made a bad choice of connector for the battery connections, so using
the existing plug/jack is unreliable. The best fix would be to just solder
wires to the pins on on the board.
Due to a minor design error, you can only chain about 3 (possibly 7)
boards together before you need to use one of the relay boards.
