Can i charge two lipos ay once?

[RichieLong]

My question is. Can you charge two lipos battery at once? I.e. link the two batterys together. Lets say for instance that i have two trakpower 3200mah lipo sticks and i link them together to make a 14.8v circuit. Then set my charger to lipo setting and 14.8v then charge. Is this possible and further more safe to do. Any advice would be appreciated. Regards Rich.

I have seen a charger that will charge two cells at once, it requires a special balance board. I have no idea if all chargers are capable of doing it.

It is not a good idea as you dont have a protection circuit looking at each cell voltage.

You really need a circuit which checks each cell voltage and then balances the cells in the string by shunting charge current away from the cell(s) with the highest voltage, alowing the others to "catch up" (this is how it works in most lithium ion batteries used in notebooks etc).

If you don have such a circuit, impedance imbalances mean you coudl have one or more cells charging at >4.20V which is a safety hazard.

you could charge them both by doing them in paralel you still have 7.4 volts but double the capacity, this is how the packs are inside the boxes

doing it as in the link will also balance them the same as when im charging my 14.8 pack i have
