Novak TC2 discharger
 

Uhmmm, does anyone else know if the Novak C2 or TC2 ESC's usually have this problem? Basically if you leave a battery plugged in (but car switched off) it slooooowly discharges it until its dead.

Not right good with my NiCads but I just went to charge the Trakpower Lipo that vicky uses and realised it was still in the car since last time she raced :( in other words it's dead - and if I try charge it, well, that would be dumb.

My fault I guess, I should have remembered about this smelly Novak thing. :(

Some of my cells seem to have touched in my box also, so at least three of my best packs are dead as well - I think that leaves 2, man, this is gonna be a fun weekend!

I think most packs will discharge if left connected to something, like a speed controller or a battery charger that's not plugged in/powered. Of course NiMH packs slowly lose their capacity if left unplugged...

The shame is that it was a LiPo and not a NiMH/NiCd pack. At least you could then have tried to revive the battery!

Matt White pointed out it was probably the big capacitor on the Novak! You're right though matt, I've revived NiMh cells in the past when I've left them hooked up - but there's no chance I'm going to risk reviving the LiPo :(
So vickys car was a bit slow at worksop the other day - still, it all worked out well in the end as she beat 4 people! yay.
