Design Lithium Charging Circuit. #37

Closed gagichce closed 9 years ago

gagichce commented 10 years ago

Specs: Charge at about 3-4 Amps. Probably will be 12v but plan for ~25v max (caps are rated at that).

We want to be able to charge and run from the battery at the same time. I want to use 2S lituim batteries but 3S are also appropriate.

Undercharging/overcharging protection should be taken care of. Short Circuit protection as well.

Should the cell be balanced? I would say no.. but if we plan on using more than one battery then maybe we should.

Also fuses... probably in the 12.. 15A range.. (don't want to hurt anyone)
