Thank you for idea! It is interesting!What about direct connection 2 18650 cells in series to the original battery? I think it will be better.

mm yes is better but i don't want modify a case and need a switch for disconnect it when internal battery is in charge (you risk if try charge 18650 battery whit internal charger.) i only study travel solution (and when i have time i want make simple holder for 4 cell with tablet)thx

I've got an idea! What if I take that canon 7200mAh battery and attach it as a second battery in paralel to internal, but with help of connector wich will be detachable,something like charging connector? I mean making a hole in body in the back and placing there input and making a cord with male connector on one side with battery on the other? On the other hand it may be better to put them in series?
