I'm looking to purchase 48 Gen 2 Nissan leaf modules (24kwh pack). The battery pack has been split, so it's just the modules, which suits me fine as I need to build battery boxed etc..
What charger do people recommend to keep the modules charged up while I do all the work? It's going to take me a few months, so I don't want to let them fully discharge...

Thanks

if they are healthy modules, they shouldn't discharge really at all will sitting

johu: typo fixed

You mean like a simple 360Vdc charger?
You can use chevy Volt charger. It can be simply controlled by PWM signal, but you still need a BMS to stop the charger

Or do you want a charger to regulate single cells?

My Batteries have been on the floor for last 3yrs, I wrote the voltage's on the packs as I disconnected them ( Kia Pack) checked out of interest recently, voltage has barely moved
