Thumper 240AH Lithium LiFePO4 Battery (Bluetooth)

At Home of 12 Volt Northern, we supply and install premium lithium power solutions designed for serious touring, caravanning and off-grid setups.

The Thumper 240AH Lithium LiFePO4 Battery delivers high-capacity, lightweight, deep-cycle performance with integrated Bluetooth monitoring and a powerful internal BMS for maximum protection.

Built using high-quality prismatic LiFePO4 cells, this battery provides longer run times, deeper usable capacity and significantly less weight than traditional AGM batteries — making it ideal for caravans, campers, 4WD dual battery systems and off-grid applications.

Why Choose Lithium Over AGM?

• Less than half the weight of a comparable AGM battery
• Maintains higher voltage for longer appliance run times
• Greater usable depth of discharge
• Increased cycle life (up to 4,000–5,000 cycles)
• Faster and more efficient charging

If you’re upgrading your caravan or 4WD setup, this battery offers serious performance gains without the bulk.
