Higher voltage=lower amps. A few guys here understand that concept, but a lot still doesn't. 8-12S lipos will mean lower capacity packs. You can still use 4-6S lipos. AMPs is what causes most of the heat found in today's systems. Yes, we want a ESC capable of 20S, I'm trying to have one made that can handles 14S. Schulze for example has a good choice of controllers for every kind of application and you can't go wrong with the 40.160 and now they have a huge 300A controller (

Schulze understand the market better then any other company out there and if a company is willing to risk who knows what with a monster like that, I would be following right behind them, but here in the USA. Even Jeti has a 300A controller, but it is only meant for the sky. Keep in my that the Thunder Power Performance Series Lithium's (
