A 14500/AA sized LiIon cell with build-in USB charger and protection.

The two cells tracks nicely and can deliver about 2A continuous before the protection trips.

I only got one curve from each battery, my automatic test equipment did not reset the protection with the short pulse I uses.


The battery works well, but it considerable longer than a regular AA cell.
