Features

• Built for deep-cycle energy storage, this Dyness 12.8V 340Ah LiFePO4 battery provides reliable power for RVs, marine vessels, trolling motors and off-grid solar systems. Featuring compact dimensions of 15.08 x 7.64 x 9.64 inches and a light weight of 59.08 lbs, it saves 50% installation space compared with traditional lead-acid battery setups and simplifies messy parallel wiring. It offers a huge usable energy of 4352Wh, exceeding the total capacity of three 12V 100Ah batteries. Equipped with premium A-grade cells and integrated smart BMS, it protects against overcharge, over-discharge, overcurrent, short circuit and extreme temperatures.
• Adopting premium A+ grade LiFePO4 cells with low attenuation and high stability, this battery supports ultra-long deep-cycle service life, lasting 6 times longer than standard lead-acid batteries. It supports flexible series and parallel connection for customized voltage and capacity upgrade. Up to 16 batteries can be combined in 4S4P configuration to build a max 69.63kWh large energy storage system, easily meeting high-power and large-capacity power demands for home energy storage and off-grid projects. Certified by FCC, CE, RoHS and UN38.3, it guarantees safe and stable long-term operation for all outdoor and mobile scenarios.
• Equipped with the latest 200A intelligent battery management system, this 12.8V lithium battery delivers a maximum 2560W continuous output power and 200A current, easily running various high-power appliances, trolling motors and multi-device loads. The built-in multi-dimensional protection system covers over 20 safety protections to prevent overheating, overcurrent, short circuit and abnormal charging and discharging. With dustproof, moisture-proof and salt spray-resistant structure, it adapts to harsh outdoor and marine environments, serving as a perfect plug-and-play replacement for traditional lead-acid batteries.
• Featuring professional low-temperature protection technology, this battery effectively avoids cold-weather damage in winter and high-altitude areas. It automatically pauses charging when the temperature drops below 0C and resumes normal charging when the temperature rises above 5C. For extreme cold environments down to -20C, it will automatically cut off discharge output to protect internal cells. This intelligent temperature control design ensures stable performance in low-temperature conditions, providing reliable power support for RV living, marine use and all-season off-grid energy storage systems.
• With strong expandability and stable output performance, this lithium battery fits multiple scenarios, including RV camping, household energy storage, off-grid solar systems, marine equipment and fishing trolling motors. We provide a 5-year official warranty for long-term quality assurance. Any questions about installation, debugging and product matching will be responded to quickly, bringing you stable product performance and worry-free after-sales experience.
