Features 5
- The Dyness 12.8V 340Ah LiFePO4 battery delivers 4352Wh of energy for RVs, marine applications, trolling motors and off-grid solar systems. Its compact 15.08 7.64 9.64 in design weighs 59.08 lb and helps reduce installation space and complex parallel wiring. Premium A-grade cells and a smart BMS provide protection against overcharge, over-discharge, overcurrent, short circuit and extreme temperatures.
- Premium A+ LiFePO4 cells provide stable, long-lasting deep-cycle performance. Up to 16 batteries can be connected in a 4S4P configuration to create a 69.63kWh system for home energy storage and off-grid applications. FCC, CE, RoHS and UN38.3 compliance supports safe and reliable operation.
- Equipped with a 200A smart BMS, this 12.8V battery delivers up to 2560W continuous output for high-power appliances, trolling motors and multiple devices. Built-in protection helps guard against overheating, overcurrent, short circuits and abnormal charging or discharging. Its dust-, moisture- and salt-spray-resistant design makes it suitable for outdoor and marine applications.
- Built-in low-temperature protection stops charging below 32F (0C) and resumes above 41F (5C). Discharging automatically stops at -4F (-20C) to help protect the cells, providing reliable cold-weather power for RVs, marine use and off-grid systems.
- Designed for RVs, home energy storage, off-grid solar systems, marine applications and trolling motors, this battery delivers reliable, expandable power. It includes a 5-year limited warranty and responsive technical support for product selection, installation and troubleshooting.
Description
Dyness, founded in 2017, is a global pioneering energy storage solutions innovator. Relying on advantageous technology and robust product R&D capabilities, Dyness has established a comprehensive product portfolio for full scenarios, including C&I and residential energy storage throughout the entire lifecycle. Dyness has provided safe, reliable, and high-quality products to over 500,000+ users in 100+ countries and regions. What makes the Dyness 340Ah battery different from a standard lead-acid battery? The Dyness 340Ah LiFePO4 battery offers up to 6x longer lifespan, 50% less installation space, and 3–5x greater energy density compared to traditional lead-acid batteries — all while delivering 4352Wh of usable capacity at just 59.08 lbs. What does the built-in 200A BMS protect against? The integrated 200A Battery Management System provides 20+ protections, including overcharge, over-discharge, overcurrent, short circuit, overheating, and low-temperature safeguards — keeping your battery safe across all conditions and environments. How does the low-temperature protection work? The battery automatically pauses charging when temperatures drop below 32°F (0°C) and resumes at 41°F (5°C). In extreme cold down to -4°F (-20°C), it cuts off discharge output entirely to protect the internal cells from damage. Is the Dyness 340Ah battery compatible with RV, marine, and solar applications? Yes, the Dyness 12.8V 340Ah Mini LiFePO4 battery is fully compatible with RV, marine (boat/yacht), and solar off-grid applications Can I connect multiple Dyness 340Ah batteries together? Yes. The Dyness 340Ah battery supports up to 4S4P configuration, allowing you to connect up to 16 batteries for a maximum energy storage system of 69.63kWh — ideal for home energy storage and large off-grid projects.
