I have always used AW 18650 1600mAh batteries in stacked, single, and boosted configurations. All charged on a pila.
I have done a little research on the best 18650, and base on this CPF users 2012 18650 tests at 2,3,5amp (est. amp draw on dual/quad/6 coil use)Battery test-review 18650 comparator I will probably get these LG-ICR18650D1 3000mah 4.35v (pink)Lithium-ion Battery (CR-ICR18650D1) Lithium-ion « Cordless Renovations if I can source them.
And this charger: CottonPickers 4.35 volt + DM (--> FS: Cottonpickers Chargers incl. Worlds smallest Li-ion charger with display )
That battery IS pretty dang nice. Good link!
Wanna borrow my charger?
