rj, can i take 2 lessor capacity 2s 7.2v packs and hook those together to gain capacity? like 2 1600mah 2s lipo's connected in series to make 3200mah 7.2v?
If you did hook them up in series, it would actually be 14.8 volts (3.7 x 4). If you hooked the two 1600 mah packs in parallel, then you would be OK. That would be a 7.4v 3200 mah pack. You could actually call it a 2S2P pack.
However, I'd not hardwire them as you would lose the ability to balance the cells. Make an adapter to connect them for operation. And then charge them individually.
