Australian start-up launches its first dedicated small-scale residential battery, a 48V 5.12kWh battery that can be easily stacked to increase capacity.

      They’d want to cheap, really cheap

      With a calendar lifespan of 10 years (at 25°C) and up to 4,000 cycles at 35°C, the indoor-only battery

      Not many places in Australia where 25° is a reasonable metric to go by. Given the rate at which anything battery powered is catching on fire, I think I’ll pass sticking one of these in my house

        The working temperature says -20C to 55C. That just seems to be what they’ve quoted the lifespan under.

      Shhhhhhh!

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

          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.
