LIPO C rating - What would you go for?

[mikeyscott]

What C rating would you go for a Cat SX running 6.5 / 7.5 motor?

Just ordered a LIPO stiff chassis and looking at changing to the Nosram LIPOs etc.

trakpowers new dark cells...........due soon

Anything above 25C continuous would be enough. However, many people have switched to 35C or 40C continuous discharge rates, as the voltage drop under load is not as large as lower C cells, therefore the cells maintain a higher voltage and so the motor can utilise more of its rpm/V (kV).

I personally run a Thunderpower 40C Lipo in my CAT, but I'd have those Trakpower Dark Series Mark has mentioned 'cos they're really nice! 35C or 40C discharge dpending on which you choose, 5C charge rates, excellent life time. Yep, I'd have them. They're about the same price as the LRP/Nosram packs, but will be more accurately rated and closer to their actual specs.

Cool

I've got Team Orion 4800 Platinum and Trakpower 3600s at the mo, but changing chassis and getting some bigger packs

I have heard some say that the 40C LIPOs have too much punch

[Marvin]

Nah. You can always alter the gearing and ESC settings to tone that down.
