I have not had a chance to try that yet. I made my 10 a123 cells into a pair of 2s and 3s packs. I could rig them all together, but that may be too much trouble, and will not fit in my current battery tray. I may try to get 10 more cells, and make a pair of 5s1p packs, but then I would not have a charger. I could make a 2s2p and a 3s2p pack, but not sure if the hypersonic charger can handle a 3s2p pack. I am sure that it can, as it can do 3s1p, and a 2s2p pack.

I am not sure if a 5s2p pack of a123 will outperform a pair of trakpower packs in series. They are 25c 4900mah, while 2p of a123 is 20-30c? and 4600mah.

Anyone care to guess what battery setup is better? I know the a123 cells drop voltage under load, and 2.8v per cell seems to be what this setup would drop them to in a 2p config. So about 14v with the 5s2p a123 pack, and something similar, maybe a bit lower, with the trakpower lipos. the 5s2p pack of a123 will be heavier than the lipos though...

Any ideas or thoughts???
