Renogy Pro Series 12.8V 200Ah Underseat LiFePO4 Battery for energy storage in demanding off-grid applications. 

Built with a proprietary compact housing material, this battery is ideal for RV installations, solar energy systems, trolling motors, marine setups, wind power systems, and mobile or off-grid environments where space and weight are critical factors.

Despite its reduced size, the battery delivers exceptional power and efficiency. It weighs roughly half as much as traditional lead-acid batteries, yet it supports 100% Depth of Discharge (DOD), effectively doubling usable energy capacity. With superior energy density, faster charging, and higher round-trip efficiency, it outperforms conventional alternatives across all key performance metrics.

Exceptional lifespan with more than 4000+ cycles
At its core, the battery uses automotive-grade lithium iron phosphate (LiFePO4) cells to ensure both safety and longevity. Designed for durability, it achieves over 4000 cycles at 80% DOD and maintains high performance across a wide operating temperature range. An integrated heating element activates automatically in cold conditions, enabling safe and reliable charging even in low temperatures, while also helping to extend the overall lifespan of the battery.

The smart Battery Management System (BMS) is a major highlight, offering robust protection and real-time monitoring. With more than 60 built-in protection mechanisms and alarm functions, the system safeguards against overcharging, overheating, short circuits, and more. Battery status can be viewed via the free DC Home app, and for even greater system integration, the battery is compatible with the Renogy ONE Core (sold separately), providing enhanced monitoring and control.

Best-in-Class Capacity and Easy Expansion
Scalability is also a strong feature of the Pro Series. Users can connect up to 16 batteries in a 4-series and 4-parallel configuration, reaching a total capacity of 48V (51.2V nominal) and 800Ah—equivalent to 40.96 kWh. This flexibility makes the battery suitable not only for standalone systems but also for larger, expandable energy setups requiring high storage capacity and consistent power delivery.
