I need a way to charge multiple Lithium Ion batteries, Yes I know they do make chargers for two lithium batteries in series but as far as I know, they dont balance them. This is one solution ive thought of, but I want to get other's thoughts before I make it. Since Im messing with lithium batteries, I may not see the short comings of the design and (hopefully) prevent disaster.
So basically I have a single Lithium charger sitting on each battery. The Inputs to the chargers are in parallel with each other, and the chargers are hooked up to each battery separately. I will be using a MCP73831 charger (They are small batteries. This IC doesnt have temp monitoring but its a small stepping stone for one that will). After the charger, the batteries are hooked up in series, so you could say the chargers are hooked up in series with each other as well.
Any suggestions on if this would work or how I could improve the idea?
