EcoFlow DELTA Pro Ultra Battery

The EcoFlow DELTA Pro Ultra is an expansion battery: it does not work on its own. It plugs into the EcoFlow DELTA Pro Ultra to extend its runtime, adding 6000 Wh of reserve with no output sockets of its own (the station manages everything).

Who is this extra battery for?

For anyone who already owns the EcoFlow DELTA Pro Ultra and finds the runtime too tight: long weekends, working from a van, longer home backup. You roughly double the reserve without buying a whole new station.

How much runtime does it add?

With 6000 Wh more in LiFePO4 (long cycle life), you noticeably extend the time before a recharge: another night off-grid, a longer run for the fridge during an outage, or back-to-back work days without mains.

Compatibility: check before you buy

This is the key point: the battery is designed for the EcoFlow DELTA Pro Ultra, and only that. It connects with the dedicated cable and the station drives it automatically. Make sure you have the matching station before ordering.
