    Shhhhhhh!

    Still funny to me they have batteries rated at 48V but, ummm… 240V 🤷‍♂️

      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.
