UPS Lithium Battery

High-Rate (HR) UPS Lithium Battery

Flexible & Scalable UPS Power

Ensure zero downtime for your mission-critical systems with Ritar’s HR UPS Lithium Battery Series. Engineered to replace traditional Lead-Acid UPS batteries, our high-rate LFP (Lithium Iron Phosphate) cells deliver superior power density and long-cycle reliability. Featuring a multi-level safety protection design, this 48V system is controlled by an intelligent BMS with full-life protection, ensuring independent charge and discharge management for maximum stability.


The standard 19-inch rack-mount design allows for effortless integration into existing server cabinets, making it the ideal choice for 5KVA to 10KVA UPS systems. Whether operating in a controlled data center or a harsh industrial environment, its wide temperature tolerance (-20°C to +55°C) guarantees consistent performance when every second counts.


Smart Data Visualization: Equipped with a 4.3-inch LED display, providing real-time, detailed operational insights at a glance.


Seamless Installation: Standardized form factor reduces deployment time and space requirements in high-density racks.


Mission-Critical Safety: Multi-stage protection protocols to prevent overvoltage, overheating, and short circuits.
