Linc - How did the 5s2p a123's work out?

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???

I'd guess the lipo's would be better, because of the weight. Also had an idea- make a thread in the GD forum for a camcorder fund for you?
