check your mamba settings to make sure that your cutoff is not turned on. I think the default is for a 2cell lipo and that will cause a standard pack to be useless after a minute or so.

hmm. Most likely the pack then. You could try cycling it a few times but I would test the mamba with another battery to eliminate that variable.

bummer, I hear URC has just released their new race pack lol. Cycling is what I would do then. No friends you could borrow a pack from, even a 6 cell? It won't be as fast but if it runs for more than 30 seconds, then it would most likely rule your battery as the culprit.

...fix up a unit so you can run that battery on your stock motor / esc etc and see what happens...it might feel better after a few runs through...It could also be a funky connection...anything under a minute sounds just TOO weird...

USB link is the way 2 go. Still sound like the cutoff is hitting. May be a glitch in the software too.

Yeah, it sounds like the cutoff is still on. If it isn't, perhaps the battery pack just sucks. Does it get hot after it cuts off? What kind of charger are you using? Which battery pack is it? The IB1200 cells?

Get a URC pack and you will be happy. =)
