Charge anytime, anywhere

DELTA Pro’s Smart Extra Battery benefits from all the charging methods DELTA Pro has, including
6500W MultiCharge. That means you can charge anytime, anywhere as long as your extra battery is
connected to DELTA Pro. Once connected, they’ll charge/discharge in uinison, keeping the battery
percent level across both units.

10-year lifespan with an LFP battery

With its upgraded LFP battery chemistry, the DELTA Pro Smart Extra Battery has a lifespan of 3000 complete cycles until it reduces to 80% capacity. You’ll get pretty much 10 years of power, even if you use it every day. That’s 6× longer than other power stations with a similar capacity and output.
