Your bank and its BMS must be able to deliver around 250A or more continuously to reach full output. A single 48V\/100Ah battery with a 100A BMS cannot do this alone, its BMS shuts down under heavy load to protect itself, so full-power systems generally use several batteries in parallel or high-current server-rack modules.
