Have a 4 Battery DPU setup and I was absolutely floored at how easy it has been to add batteries to the DPU. The hard part is getting it out of the shipping box (you really need 2 people to move the batteries). Just turn off the DPU, set the extra battery on the existing stack, plug in the cable and turn it back on. The app finds the connected battery and voila you got an extra 6kWh of capacity. EcoFlow really knows how to do things simple when it comes to installation and setup! Plugged in my EV charger via the xStream cable and in about an hour had the new battery fully charged with the others in the stack. Yes it’s pricey and hope the price continues to come down.
