Well I was looking at $40-50 controllers but thought the Crystalyte was much more $.
I found that one for $20 less and I'd rather spend a little more on a brand I trust.

I'm well aware that most brushless controllers are not suitable but it's more the amperage
that confuses me and most of the specs on this lithium battery..
Would the 25amp version you've suggested, X-CT4825S, be better than the 30amp Crystalyte Sparrow model, X-CT4830S with the above battery? What difference will an extra 5amps make?
