No price range?
Shhhhhhh!
Still funny to me they have batteries rated at 48V but, ummm... 240V ๐คทโโ๏ธ
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.
