brushless and A123 questions

[Finnster]

Like Clod pointed out, the adv of the A123s cells are safety, durability, lifespan and cost. I run A123s, but I may get 1 ltwht lipo pack for racing. Also note, that the A123s do not lose performance over theirlife span, only capacity. The IR actually goes down w/ age, so they get better, but lose capacity only. NIMH IR goes up ovr the life, so they lose power and cap. In short A123s are heavy but badass cells.


FWIW tho, they are limited to 70A discharge (30C) before they drop alot of voltage. You are prolly pulling 100A+. You need 2P.

5S2P is nearly equiv to a good 4S lipo pack. Mine weighs 780g. My TrueRC 4S 8K pack weighs ~700g, so... Runtimes were 25min vs 1hr bashing around.

you lose a bit of top spd w/ 5s over the 6S, but much better runtime and not abusing the cells. For a basher the weight is not that big of deal, and still weighs less than a 12cell NIMH pack.
