$119 for a 4500mah 2s2p pack. I would need 3 of these (6s2p 4500mah total) = $360. Wouldnt be able to fit them in my truck (or any truck pretty much) without ripping them apart and making them into 2x 3s2p packs.

A pair of 5s 4000mah 25-35c Zippies cost me $200.

I sincerely hope these Life appear in different configurations and from other companies, at a much better price point in the near future.


thats what the $100 bounty on finding the cells seporate is for:lol:

Those are not the same cells. From what I know, there's only 2 places that makes 30C LiFePO4 RC packs, one starts with a H and the other with a Y, but they use higher capacity cells. The cells MA claims to use are 2250mAh.

I think I found some flat LiFe cells. Made by Hyperion. Marketed as RX and TX packs.

20c

Metallover 07.21.2009 11:32 AM

Lets see, the 3000 and 3800mah cells are 20c discharge and the rest are 5c discharge. That means there could be different cells maxamps uses or they use the 5c or 20c cells. Maybe there is a 30c flat LiFe cell.

However, this chemistry is better suited in e-bikes and I guess transmitters because they have a long life, they are durable, they charge fast, and the power/weight is pretty good. They don't have the flattest discharge curve however..

Metallover 07.21.2009 12:12 PM

Sent an email to all e rc asking if their cell source has any other chemistries of LiFe like a 30c. I think all e rc is the hyperion headquarters...
