[QUOTE="Crankshaft, post: 783187, member: 941"] I have got hold of 30 x Samsung 18650 li-ion cells from an old 36 volt battery pack. The majority of the cells should still be good as it from a pack that bricked after only a few hours of use. I'm thinking of going with a 4S6P configuration. Saw the charge/discharge PCB's on eBay. Are these what I should be looking at? http://www.ebay.com/itm/Cell-Balance-4S-30A-14-8V-Li-ion-Lithium-18650-Battery-BMS-PCB-Protection-Board-/322480487728?hash=item4b1555bd30:g:e2oAAOSww3tY7TNO http://www.ebay.com/itm/4S-Li-ion-Lithium-Battery-18650-Charger-Protection-Board-15A-14-4V-14-8V-16-8V-/141807702415?hash=item210465d18f:g:fvsAAOSw241Yga5c The Tripath amp likes 12-14 volts so I should be able to power it without any voltage adjustment. Perhaps the innards of a car-style USB adaptor could work for the 5 volt requirements. Then I also need a charger. Seeing the above PCB's are supposed to requlate the charge current and voltage, will it be OK to use a DC supply with approx. the voltage required - 14.8 volts? Any help will be appreciated. [/QUOTE]
