Any opinions on how and if these will influence the race scene. After a couple of years everyone seems happy again with lipo. I imagine that with the lower voltage these batteries would only be used if they had a seperate class?

I'm not really sure at this time what or if they will have any affect on racing at this point. Of course they would have to be allowed first. I can say that I have seen guys run the smaller A123 1100 cells against 2S Li-Po's in 1/18th scale racing and they performed just as well and one guy was even winning. They do have the potential, but at this point are main goal is to offer a pack that will perform well, charger fast, and be very safe for those new guys to the hobby that don't want to take that plunge into Li-Po's quite yet. You could consider these packs as a stepping stone so to speak. They have the look, the feel, and pretty much the same charging procedure as a Li-Po pack but with out the worries that push some away from a Li-Po.

Yes they have a niche in quite a few places.

Voltage under load is just like that of a Li-Po. Recovery from high amp draws is even faster.

i thought the voltage drop on a123/life/green cells is a hell of alot lower than that of similar lipos....

If your comparing voltage to voltage yes there is a difference. They aren't the same voltage to start with. But the discharge under load looks just like a Li-Po. A nice smooth flat line. They don't drop under load like a NimH pack does. They hold their voltage really well and as I stated they recover from high amp spikes really fast.

Are these packs LiPo with some circuitry added inside the pack to protect the cell/s from being exposed to improper charging or discharging?
