I would try to keep your cells under 150 or 160 degrees... My race cells used to get up to 180, but they wouldn't last long at those temps...
Guys... I know it's difficult for some to consider, but I would REALLY advise you guys give up on this NiMH deal with these, and just make the plunge into Lipos...
A pair of MaxAmps 4000 or 5000 or ??? mah 2S1P Lipo packs with Deans connectors will give you more power than any pair of 7-cell Nimh packs, WAY less heat, and WAY more runtime... WAY more speed... WAY more useful cycles... WAY easier charging... WAY...
You are fighting an uphill battle with NiMh on all fronts... They are heavy, short lived, have high resistance... have to be "peaked" get to prime performance... and don't, can't, and will NOT provide the same power as an equivalent Lipo pack...
I've run mine in P-Mono heat races with not other mods than a HUGE prop, a bigger turn-fin, and a pair of 2S1P 3300 mah Lipos... and it's a ROCKET... Quick, Fast, and Stable... It's even faster with the 2S1P 4500mah 30C packs I tried last time out...
If you insist on using NiMH... you are going to be limited on prop size, and if you are buying "cheap" sport packs, then they are going to run warmer... that's what makes them "sport" packs... more internal resistance and less peak V...
I know money is tight... but I'm telling you... a one-time investment in an approriate set of Lipos, which can be charged on any Triton 2 or ICE charger, will pay back big time in longevity and performance...
