Harness greater capacity Attach the additional battery to RIVER and harness a doubled capacity of 576Wh from 288Wh. To install, use the screwdriver from the module tool kit to secure the additional battery to RIVER.
A storage upgrade for less If you’re looking to upgrade RIVER, adding an additional battery gives you double the capacity for less. All the while, RIVER’s BMS monitors your battery to keep it safe.
Lightning-fast charging Even with an additional battery, the speed of charging RIVER from a standard plug socket is the same. With 0-80% charge in under 60 minutes and full charge in 1.6 hours, you won’t even notice the additional battery there. This is all thanks to EcoFlow’s X-Stream technology.
Power more devices With doubled capacity coupled with RIVER’s X-Boost mode, you can power devices up to 1800W. This should cover you for home appliances and in some cases, power tools.
With the EcoFlow patented X-Stream Technology, the smart inverter enables a fast rechargeability. Even after adding the Extra Battery to RIVER, recharging time from AC wall outlet of the combined unit remains the same, with less than 1 hour to charge from 0%-80%, and fully charged in 1.6 hours from an AC wall outlet.
Perfect for that little extra when you need it. Makes the unit a really good travel companion in the car or on the boat. Charged for free by the GA Sun is a win!
Very easy to throw it on, works perfectly and I'm super impressed with the extra battery as well as the ecoflow river
Perfect less than 5 min to install. Works great heavier though.
The service received for returned idem was very good. Person that I spoke with did a very good explanation of what I needed to do and send all information quickly. Thank you, Charles
I honestly have no cons to say about the extra battery. Excellent option to expand the performance of such a compact powerhouse of portable power ingenuity.
