The battery is 48V DC. It uses an inverter to produce 240V AC, similar to solar installations.

Yeah, but does that mean a 48V 5.12kWh would be (roughly) equivalent to a 240V 1 kWh battery?

Sorry, I'm only kinda familiar with power tools and bikes etc where the motor/output is rated the same as the battery itself....

meh, I guess the volts don't matter. All the other batteries are rated at Ah, not kWh....

5.12kW is 5.12kW no matter what the voltage is. I think you might be confusing current (amps) with power (watts).

P = IV

P = power

I = current

V = potential difference (voltage)

so 5.12*10^3 W / 240V = 2133.33A ---> 2.13 kAh

vs

5.12*10^3 W / 48V = 10666.67A ---> 10.67 kAh

so yes, it will last longer at 48V but calling it 5.12kWh is not misleading

Yeah, thanks. I kinda figured it out that I was confusing the other batteries being rated at Ah, not kWh.

But I appreciate you spending the time to set it out clearly.

Have a good one.
