Really big brushed ESC

I'm going to attempt a hobby grade swap on a 1/4 scale toy car. Since it'll never be a serious competitor, I want to keep things cheap and stick with brushed motors. I'm looking for a really big brushed ESC, physical size isn't important, but high amp capacity is and it's got to work on 3 cells(doesn't need a Lipo cutoff though, I've got that covered). I see cheap "320A" ESCs all around the internet, but they are only good for up to 10V. Even an old mechanical speed control would work as long as it's high power. Anybody have anything laying around they're not using? Thanks.

why not grab a hobbywing or hobbyking Brushless ESC? You can get their 80A one that can handle 4S lipo for like $40

I've got a Tekin 420G2 ESC. It is not tremendously huge but it has a high current rating (350 amps, see here: and can run upto 20 NiMh cells (equivalent to 6S LiPo). It does not have reverse or LiPo cutoff. .

I want $40 shipped (to a U.S. Address) for it.

Some brushless esc's can be programmed to work with brushed motors... I had a mamba max esc running a brushed motor in my rock crawler for a while. Don't dismiss a brushless ESC so quickly. Might be a wise investment too, in case you'd ever like to to use the esc for another application later on.

I don't know which other ones out there have the capability, and if any that do are rated for that many amps & are cheap, but it's probably worth doing some quick research
