Default Re: High voltage lithium

Plans are to test two methods.
One is, no bms. Set DeltaQ to proper pack voltage and manually balance when needed.

Second is untested.
Importing a pallet of single cell 10 amp 4.2 volt chargers.
Build a 12s off-board charger and harness to plug into standardized plug for all my vehicles.

No idea if this will work. They are shipping next week. Jumped in with both feet.

If it works, cells will be top balanced every charge cycle, for maximum capacity.

I have devised a way to adjust the point, at which controller shuts down, on low voltage.

No complicated bms. Need a charger in any case.
Even with chargers, total cost will be <$1500-96ah-25M range. <$1000- 47ah-12M range.
