How to build battery pack 9.6v from 18650 batteries?
I have some panasonic cgr18650cg batterys here. But when 3 in series, the voltage is higher. Maybe the drill can work with a higher voltage but I dont know. Will it work, would like to create first a 3S pack and maybe later a 3S2P
I need a PCB and thinking something like this one : http://www.ebay.nl/itm/12-6V-8A-w-Balance-Li-ion-Lithium-18650-Battery-BMS-PCB-Charger-Protection-Board-/321853922824?hash=item4aeffd1e08
Or this one?
And how to charge a pack, can I use a common 12v laptop adapter or other adapters or specia li-ion charger? I dont think the original ni-cd charger can be used with pcb's above?
