A123 M1 - Where to buy?

[Hell-e-Guy]

Hi Guys,

I want to try using these cells, but can't seem to find a source.
Where can one find them???

B.T.W - Is it correct to assume that a 3S LiPo pack should be replace by a 4S M1 pack ?

Cheapest source appears to be DeWalt DC9360 36v batteries on ebay. Contains 10 cells.

3 lipos are between 3 and 4 A123s because lipos charge to 4.2v and A123s to 3.6. Their nominal voltages are about 3.7 to 3.1v and under load may be 3.3 vs 2.7v.

4 A123s gives a nice improvement over 3 lipos because they are a slightly higher voltage and their voltage under load stays constant. However, your ESC and BEC have to be able to handle this higher voltage. You also need a charger that charges to the correct voltage; can be made simply and cheaply.
