Australian start-up launches its first dedicated small-scale residential battery, a 48V 5.12kWh battery that can be easily stacked to increase capacity.
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
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 5.1210^3 W / 240V = 2133.33A —> 2.13 kAh
vs
5.1210^3 W / 48V = 10666.67A —> 10.67 kAh
so yes, it will last longer at 48V but calling it 5.12kWh is not misleading
No price range?
They’d want to cheap, really cheap

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 🤷♂️
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…

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.
There’s a certain knowledge threshold on any given topic, below which your participation just makes you look dumb.
Thanks, bro. That’s a great comment to encourage participation.
I’d hate to learn anything. And your comment achieved that.
