Default Li-Ion charging

So far this is working great.

12 X 1s off-board charger.

Standard plug on all my cars.
Plugs into Chevy Volt bms port.
Batteries top off and balance, each charge cycle.
No other bms needed.
Get full use out of pack by full charging. Or use a timer to end early.

Looks complicated, yet simple.

This is just proof of concept. My real 1s lithium chargers aren't delivered yet.

If I knew how well this worked, would not have ordered the chargers. These are CC-10A CV-4.2 power supplies. I can make a 5A-12 cell charger for less than $250.

Post #1 shows 12 cc/cv isolated supplies. Used to charge a 12s volt pack.

Here is another charger. 5A X 12 with enclosure and fans.

Latest project is 12s balance board.

Will top or bottom balance up to 12s, to a point, that can be set from 2 volts to 15volts.

Balance current > 5 amps. (shunt)
