Bought this plus the extension cable to add to my portable power station. I have regular power outages, one of which recently caused my fridge/freezer to be off for several days while I was away. With this new battery added, the fridge will stay powered when the grid goes down & there's enough energy for approx 6 days. The price was excellent value, free & fast delivery, & the packaging was really solid. I travel frequently so am already considering getting another one to connect my internet, security system, & other devices to ensure I can remotely monitor & keep my whole house powered during cyclone season.

Revolutionary 4-in-1 Battery
Unlike a conventional battery designed for only one task, the WattCycle 24V 314Ah combines 1800 CCA engine-starting capability with 8038.4Wh of deep-cycle energy. Start the truck when it is time to drive, then use the same battery to support compatible onboard electrical loads during stops.
Four Smart Functions in One Truck Battery
The battery combines dual-purpose operation, Bluetooth monitoring, self-heating and low-temperature protection in one 24V LiFePO4 platform. Together, these functions help simplify battery management across long-distance driving and changing European weather conditions.
Designed for Popular European 24V Trucks
Designed for compatible European heavy-duty platforms including Mercedes-Benz Actros/Arocs, Volvo FH/FM, MAN TGX/TGS, DAF XF105 and Scania R-series trucks.
Dual-Purpose Power Built for Heavy-Duty Work
Combine 1800 CCA starting power, 8038.4Wh deep-cycle energy, a 200A BMS, Bluetooth, Forced Start and self-heating in one battery. Rated for 6000+ cycles at 80% DoD, it is designed for repeated starting and auxiliary-energy use in demanding applications.
Robust 200A BMS for Heavy Truck Loads
The integrated 200A BMS supports up to 5120W continuous DC output, giving the battery the capacity to run multiple compatible truck loads. Built-in protection covers over-charge, over-discharge, over-current, short-circuit and abnormal temperatures.
Monitor Your Truck Battery by Bluetooth
Built-in Bluetooth connects the battery to the WattCycle App for convenient real-time monitoring of battery status, temperature and cell information. Drivers can check important battery data directly from their phone without accessing the battery compartment.
More Deep-Cycle Energy with Less Battery Weight
At approximately 55.4kg, the WattCycle battery stores 8038.4Wh while combining a 200A BMS and smart monitoring in one system. Its LiFePO4 design offers substantially higher cycle capability than conventional lead-acid alternatives for repeated deep-cycle use.
Choose the Right Dual-Purpose Battery for Your System
The 24V 314Ah model delivers 25.6V, 314Ah, 8038.4Wh, 1800 CCA and a 200A BMS, making it the highest-energy option in the WattCycle dual-purpose range shown. It is designed specifically for compatible 24V heavy-duty systems and does not support series or parallel connection.
Power Cab Loads Without Unnecessary Engine Idling
With more than 8kWh of stored energy, the battery can supply compatible onboard electrical loads while the truck is parked, reducing the need to run the engine solely for auxiliary electricity.
Beyond Trucks: Power for Demanding 24V Applications
The dual-purpose design can support compatible heavy-duty trucks, agricultural equipment, marine systems and off-grid applications requiring both high-current capability and substantial energy storage.
Heavy-Duty Energy for More Than Road Transport
The combination of 1800 CCA starting capability and 8038.4Wh deep-cycle storage makes the battery relevant to compatible agricultural, marine, heavy-machinery and industrial 24V systems. One dual-purpose battery can support applications that require both high starting current and sustained auxiliary energy.
