The DELTA 3 Max Plus Smart Extra Battery in brief

Four extra batteries on a DELTA 3 Max Plus lift the system to 10,240 Wh. Each one adds 2,048 Wh in LFP cells and weighs 35.3 lb. This is the battery sized to that one station, with no other host in its list. The station holds 2,048 Wh too, so each battery you add is the size of the unit itself.
