There is no battery that requires any sort of charge rate, charge rates are entirely up to the end user. All I am saying is that if a battery manufacturer claims a max charge rate then it is entirely safe to assume that the battery will more than likely not erupt at that rate any more than it would at a lower rate.

FYI, my ThunderPower 6s 5000 packs were rated to handle a 60amp charge rate (12C) max and I did so every charge for well over 200 cycles with no noted decrease in pack performance.
