But the real issue with battery chargers is a thing called battery "acceptance rate." Historically, we used a value of 25-30% of a battery''s amp-hour rate as the maximum acceptance rate. Translated, this would mean that a 100-Ah rated battery would gain no advantage connected to much more than a 25- 30-amp rated battery charger.
To calculate the Wh of an ebike battery pack, we simply multiply its V and Ah to get the Wh. A battery rated at 36 V and 10.4 Ah will have a 417.6 Wh capacity (36 x 10.4 = 374.4), like on the Eunorau UHVO All-Terrain Ebike; A battery rated at 48 V and 21 Ah will have a 1,008 Wh capacity (48 x 21 = 1,008), like on the Bakcou Mule.
Watt-hours = watts * hours = 250 watts * 5 hours = 1250 watt hours. Account for the efficiency of the inverter, say 85%. Watt-hours = watts * hours / efficiency = 1250 / 0.85 = 1470 watt-hours. Since watts = amps * volts divide the watt hours by the voltage of the battery to get amp-hours of battery storage
