I need more storage capacity for my delta 2 max generator so I purchased the smart extra battery. It works seamlessly with the generator and the ecoflow app brilliantly monitors all the inputs and outputs from my two 220 watt and three 110 watt panels

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.

Presently own a older Delta Max, and a Delta 2. The Delta 2 Max expansion battery is compatible with both units.

I purchased the D2M SB to augment and double the storage capacity of my D2M and I think that was a wise decision. With the 2nd battery, the unit can keep either my refrigerator or a dedicated freezer running for over 2.5 days, close to 3. The only think I would like to see different would be for the SB to discharge first and a way to recharge it directly so it could be recharged while the D2M unit is still keeping the systems alive.

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

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.
