Roamer 340SMART5 12V 340Ah LiFePO4 Lithium Leisure Battery
Meet the Roamer 340SMART5, a new compact battery shape for our 5th generation range. 340Ah of high power LiFePO4 is perfect for off-grid vehicles with high energy demands but its also small enough to fit in tight spaces, including under a passenger or driver seat of a motorhome (vehicle dependent). The integrated Battery Management System (BMS) with Bluetooth provides remote monitoring via the Roamer BMS app and a market-leading discharge rate of 300A (450A peak) lets you run any domestic appliance up to 3600W via an inverter.
