What amp should I charge my LiFePO4 battery?

Now if you have a 48V 100Ah battery (5kw server rack) the charge current is the following: 100Ah * 0.5C = 50 Amps.

pwm

This is not to dispute any negative effects of pulsing on cycle life altogether, because it is clear that ohmic losses in the battery will increase when continuous current is replaced by a charge-equivalent pulse current, simply because its RMS value is higher and the ohmic losses scale as I^2*R. So, the question is not "if" but rather "to what ...
