EcoFlow DELTA Max Smart Extra Battery

Please need assistant can you contact me

The whole Delta Max ecosystem is fantastic. I’ve been using different solar generator and power pack systems for several years now, and Ecoflow is definitely the gold standard. Love the Delta Max and extra battery, perfect size and function for backup and mobile power.

Works great. I am currently using it as an UPS to power my computer.

In a world of declining Lithium and chip availability, I was delighted to find this battery on sale from Eco Flow right after I purchased the generator. It charged and discharged, per the owner's manual and literature advises. I purchased it for SHTF scenarios and so there it now sits inside it's Faraday bag @ 30% charge awaiting it's day to be recharged to 60% in three months and discharged down again to 30%. Hopefully, I'll never need it but if I do, I'm very comfortable that Eco Flow has provided me the product to keep things going on my end.

I have two of these batteries for my unit, I will have a good extended time for backup. With global warming no one knows when they will lose power. If I need to evacuate I have power on the road i can even put in the trunk of car to have power. I also use a solar panel.
