Are Zippy Lipos safe with a Castle MMM Speedy?

[MrMin]

I agree. I also think zippy-r's are very impressive. The mmm is more powerful than the mm, but had some teething problems(which seem to be gone now) and now is pretty reliable. The mmm does not fail more than other (much more expensive) esc's. Chinese alternatives are coming out such as the 150A etc... i think the mmm should really have some more protection circuitry to prevent this, but IT really was expecting a much more luxurious environment.

I think the components are running nearing their limit on 6s, only when you brake, when and it blasts energy into your batts too fast(faster than it can absorb) then it will kill the capacitors(ripple current) and ESC FET circuitry up in smoke it will go. Fact is that the mmm requires good (expensive) low resistance good chemistry batteries because that is what it is expecting in order to operate.

I think castle is only saying that he would prefer it if you didn't use cheapo (not necessarily zippy) batteries because they do not want to replace ESCs exploding due to this. I'm personally working on a protection circuit to protect my mmm's just in case.

Less is more. more or less.
