Amazing system, with just one flaw.
This system is great for my needs, my only complaint is should be an ac cable designed to charge the extra battery separately. Other than that one flaw it’s a perfect system.

Working Well
Boosted the storage of my Delta 2 Max Pro. Worked well over 2 power outages and recharge was fairly quick.

Extra Smart Battery
The smart battery is great. Was real easy to click it into my Delta Max main battery. Not sure if it is supposed to show up on the Ecoflow app or not, which I do not see currently. But have not drained the Delta Max enough to test it fully.

Takes my delta 2 to the next level
Easy plug & play, hard to talk about something that just works I plugged it in and never needed to do anything else, it just quietly worked. I wish more was this seamless.

Great product
Bought this product for a backup and use this to power my iceco refrigerator. Would love EcoFlow to put usb and 12 volt on the extra battery. That would make this product very outstanding.

Over should be good system for Direct Vent Furnace
I haven't needed it as of yet, but purchased a month ago and sized for AC backup to a Rinnai direct vent wall furnace. Calculated the draw of furnace and sized the EcoFlow system for appox. continuous 4-days operation without wall power. Combo of Ecoflow Delta 2 power system and Delta 2 Max smart extra battery provides 3 kWh of power. Only downside is that you can't disconnect, remove, and recharge the extra battery on it's own. That's what I had in mind when purchased. That way I can keep running furnace with the partially charged Delta 2 alone, while I take away the extra battery to charge it back up to 100% and return and plug it back into Delta 2.
Not the case. You have to use the Delta 2 power station as the conduit to charge the extra battery. So, you'd have to remove the whole combo system to charge both the main Delta 2 and or the extra battery.
It would be a great design improvement if EcoFlow added and A/C charging input port on the Extra Battery, so it can be charged by itself.
