Good additional battery
I bought the additional battery to go with my Delta 2 Max and four solar panels. Setting up is very straight forward and the connect cable is easy to use. The Delta 2 Max instantly recognizes the battery and it even shows on the Eco Flow app. I connected both to my solar panels and charged them to 100% as I was curious to see how they would balance out as the new battery arrived at 60% charge and my Delta 2 Max was at 75%. Charging was quick from my solar panels as the Delta 2 Max shunted much of the power to the extra battery until they were both at the same charge level and then the load evened out. I think it’s a great addition as now I can generate and store 4 KW hours of power. My plan is to add a second smart battery so as to max out at 6 KW hours. The smart battery weighs almost 10 pounds less than the Delta 2 Max and is easy to move around. It’s size allows for easy storage in a on top of the D2 Max.
