is a great store, if you give them a diagram they will build you custom packs too,
ive got a problem, my chassis is too small for a AA style batterypack, im only runningf 2 130 can motors, which draw about 1A each, the biggest 5-6cell i can fit is a 2/3A cell, they run between 1100 and 1500mah, those should work fine right? since (gunna say 3A to count in amps for led, electronics, sensors and the robot stalling every once in a wile) would give me 30minute run times...
mega, i know i am probobly going agenst the flow, but im gunna recomend agenst ni-cd's, unless you happen to have a discharger, a peak charger, and a trickle charger lying around. they have memory, and if not properly discharged, they will only discharge partway in the future. also, i think you should have 5 cell at least, since the board is supposed to get 5v and 4X1.2=4.8, but im not totaly sure on that.
