Add another 3,600Wh to your DELTA Pro setup with a smart extra battery at $1,399 low for today only (Save $1,400)

$1,400 off $1,399

Alongside EcoFlow’s ongoing Halloween sale, the brand has launched the first of its scheduled 24-hour flash sales, with today’s offering the DELTA Pro Smart Extra Battery for $1,399 shipped. Normally priced at $2,799, it spent the first half of 2024 repeatedly falling to $1,599 with each discount, until July saw things fall a little lower to $1,499, followed the next month by a drop to $1,399. Since August we’ve seen it keep above $1,469, with today’s flash sale giving you another shot at the 50% markdown that not only returns costs to the all-time lowest price we have tracked but also lets you double up your existing DELTA Pro’s battery capacity for even longer-lasting backup power.

With EcoFlow’s DELTA Pro smart extra battery back at its lowest price, you’ll be getting the best deal to double your power station’s 3,600Wh LiFePO4 capacity to 7,200Wh, giving you longer-lasting backup power to cover off-grid camping needs, small business support (such as food truck appliances), and even powering your home necessities during sudden power outages. There’s a bright LCD screen for quick performance readouts at a glance or you can monitor and control everything from your personal devices through the EcoFlow app.

One thing to keep in mind here in terms of total home backup support – you’ll need to already have a few more DELTA Pro stations with their smart extra battery setups (up to the 25kWh maximum) alongside the transfer switch and power cord to carry your home’s entire breaker, or invest in a larger backup unit.

You’ll get the same recharging rates through this unit that you get with its power station counterpart, with the two sharing a 6,500W MultiCharge, letting them charge/discharge in unison once they’ve been connected together.

Be sure to check out the entire lineup of power stations, bundles, smart devices, and accessories that are benefitting from up to 51% off discounts through the rest of the month, with two more planned 24-hour flash sales on 26, and 29. You’ll also find Bluetti has a similar Halloween sale currently running too, which is offering the very first chance to save on the new Handsfree Backpack Power Stations. You can find even more backup power solutions at a discounted rate in our Green Deals hub.
