Can you give any more specs? Discharge rates(MAX, BURST & CONTINUOUS), and weight. Exterior dimensions too but not totally necessary.
Just to make sure. 2300mAh and 11.1volts right?
Hi, these are A123 cells, so the chemistry is different than standard lipo. They're rated at 3.6 Volts/cell and you need to build the packs in a way similar to NiMH building. Their discharge rates are, in theory, 60 amps continuous/120 amps burst. In reality, 40-60 continuous and 80 burst is probably more reasonable. They are can-shapped and weigh about 74 grams/pop.
If you google A123 cells you'll find a lot of info on them--they're the same cells used by a123racing.com (that site appears to be somewhat down for some reason...).
The main thing about them is they are a bit heavier than lipo from a capacity standpoint, but can deliver at least as much power and are very robust. They can be charged easily at 4C (15 minutes), and some charge at 6 C or higher, for hundreds of cycles. They can be used for many hundreds of cycles without an appreciable loss in capacity and tolerate over-charge and over-discharge gracefully, unlike a lipo will will destroy itself if that happens.
Most decent chargers now have an A123 setting, but you'd need to look for that first to be sure.
I ordered 11 cells from JWilliams a week ago last Monday. I sent the money order out and 7 days from my mailing the cells were at my door in a very well packed box.
Very good communication and very fast service.
