  • For 2 - 3.7v LiPo batteries in series you would need 2 of these and connect one across each battery. Each one would charge its own cell, which is actually more desirable with LiPo cells anyway. A slight difference in their internal resistance will cause different charging rates in series. This causes lots of problems in the life of series cells unless they are matched. Even then, for the long life of the cells, they should be charged individually.

No public wish lists :(
