If you have a 12V 200Ah battery, the maximum charge current is as follows: 200Ah * 0.5C = 100 Amps. Now if you have a 48V 100Ah battery (5kw server rack) the charge current is the following: 100Ah * 0.5C = 50 Amps. We can see that the maximum recommended charge current depends on the battery capacity (Ah), not the voltage.
