Can the lipo charger handle any voltage? I have a 7.2v lipo battery, 800mah. Not sure if it is a 3 or 4 cell but I'm sure it would be one or the other. I don't want to damage or explode my battery so best to be certain before I go plugging anything in.

The charger being used is the BQ24010.

Datasheet says it charges at a rate of 4.2V, so no... probably won't work with a7.2v battery or it'll charge really slowly. Not entirely sure. It's also designed for single cell batteries FYI.

A fully charged LiPo cell is 4.2V however the nominal voltage of the cell is 3.7V. The LiPo charging IC can only handle a single cell and it would not be recommended to use a 7.4V pack as this will damage the IC most likely, using it on the EXT connector should be ok though.
