So if you have 5 1.2v 2000 mah batteries and you wire them in parallel, you get a batt pack with 6 volts, but 2000 mah. If you wire them in seris, you get a pack with 1.2 volts, but 10000 mah, or 10 amps.
Sgt., I think you got your series & parallel backwards - a series connection increases voltage and leaves capacity (mAh) the same, where a parallel connection increases capacity and leaves voltage the same. Just clearing things up [8D]
