bit low on mAh. and therefore, in most cases low on peak amps too.

Ive had my eye on this eBay shop for a while now for batteries - not bought any yet as Ive still to work out what I need, but they seem to have some moderately priced packs that should be suitable for robot combat

I wouldnt bother touching vapex nimh. I bought six of the 3300mAh packs. Tried to run two 6v packs with 2 golds and they couldnt supply the current needed. I used two 15amp electronize and they didnt even get warm so the figures that they brag are garbage. So I then had to buy 2 sets of nicads and they could happily supply the required current.

A tip - If you are going for nimh anything short of saft cells at £5 each are a waste of money. Go for nicads instead.

Just thought I would add that I did find a use for the nimh..... Supplying current to a custom made laptop cooling device so its not all bad!

Ive just put the GP3700 NiMh in Alpha and ive been very impressed with them, i got a set of sanyo 2400nicads about a year ago and they couldnt handle it, after my poor sanyo 3000nicad botpacks have finally gave up.

Ive been running the same ni-mh GP3300 packs for a couple of years now, excellent cells.

I use GP3700 cells NiMh in Hannibal (heavyweight) and Sanyo 36000s in Hannibalito (featherweight). Both perform excellent with them. I did put 3 36V packs in parrallel in the heavy though. Hannibalito runs on 1 pack 19,2V.

that 3600s, not 36000s.
