The all-new Roamer 230SMART3 is a compact LiFePO4 leisure battery with internal Battery Management System (BMS), Active Balancing and Bluetooth monitoring. With 230Ah usable capacity and a market-leading 250A continuous discharge rate (500A peak), this little powerhouse lets you run any domestic appliance up to 3200W. Our 3rd generation model has a 15% capacity increase over the previous version but uses the same compact case, allowing it to squeeze into the tightest of spaces.
