Provides stored energy for lighting, refrigerators, water pumps, communication devices, entertainment systems and compatible inverter-powered appliances in recreational vehicles, camper vans and caravans.
Suitable for small solar systems, cabins, remote equipment and other installations requiring a reliable 12V deep-cycle battery bank.
Can supply compatible onboard electronics, navigation equipment, lighting, pumps and other auxiliary loads in boats and small marine applications.
Suitable for communication equipment, emergency lighting, security systems and compatible low-voltage backup power installations.
The 300Ah capacity provides 3.84kWh of stored energy, offering longer operating time than lower-capacity 12V batteries.
A maximum continuous discharge current of 200A allows the battery to support compatible inverters and loads rated up to 2560W.
The battery provides more than 2,000 cycles at 100% depth of discharge and up to 5,000 cycles when operated at approximately 80% depth of discharge.
LiFePO4 chemistry is designed for repeated charging and discharging, making the battery suitable for mobile, renewable-energy and auxiliary-power applications.
The integrated battery housing provides substantial storage capacity while maintaining practical dimensions for RVs, boats and compact energy systems.
For safe and reliable operation:
Use a charger specifically compatible with LiFePO4 batteries.
Set the charging voltage within the recommended 14.2–14.6V range.
Keep the continuous charging current at or below 100A.
Keep the continuous discharging current at or below 200A.
Do not connect loads or inverters exceeding 2560W.
Confirm cable size, fuse rating and terminal capacity before installation.
Consult the supplier before making series or parallel connections.
