Product Details

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 32°F (0°C) and resumes above 41°F (5°C). Discharging automatically stops at -4°F (-20°C) 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.
