Piggy Backing a lithium battery (cell) Answered
I have several questions. But the basic idea is that I want to extend the runtime of a device (such as a cell phone, tablet, camcorder, whatever) by increasing the mah. So here are the things I am wondering:
1)Many lipo batteries have 3 or 4 contacts, one is -, one is +, and the others are typically data or something. can I simply connect additional lipo's (just the + and the -) in parallel with the corresponding contacts in the device?
2) Are there any ill effects of charging (presumably from the built in charger of the device, like a cell phone) and discharging (using the device) parallel lipo's?
3) They will all have the same voltage rating, but do they all have to have the same mah rating?
