Rack Power Storage

Lithium Iron Phosphate Battery

LP18-4850 (51.2V/50Ah)

Our battery module consists of multiple cells connected in a series and/or a parallel, encased in a mechanical structure. The system is modular in design, allowing for it to be easily switched to a different capacity and power as per your demands. The unit can be wall mounted, floor mounted, and server rack mounted.

APPLICATIONS

Lithium Iron Phosphate can be used in most applications that use Lead Acid, GEL or AGM type batteries.

Suitable applications include:

•Solar Storage
•Switching applications and more
•Base transceiver station
•Communication equipments
•Central office
•Telecommunication systems
•Electronic cash registers
•Microprocessor based office machine
•UPS

FEATURES & BENEFITS

High cycle life

6000 Cycles (25℃, 80% DOD) for effectively lower total of ownership cost

Longer service life

Low maintenance batteries with stable chemistry.

Built in circuit protection

Battery Management System (BMS) is incorporated against abuse.

Better storage

up to 6 months thanks to its extremely low self discharge (LSD) rate and no risk of sulphation.

Quickly recharge

Save time and increase productivity with less down time thanks to superior charge/discharge efficiency.

Extreme heat tolerance

Suitable for use in a wider range of applications where ambient temperature is unusually high: up to +60°C.

Lightweight

Lithium batteries provide more Wh/Kg while also being up to 1/3 the weight of its SLA equivalent.

CAUTIONS

•Do NOT short circuit, reverse polarity, crush or disassemble.
•Do NOT heat or incinerate.
•Do NOT immerse in any liquid.
•Store at 30~50% SOC. Recharging every 3 months is recommended. The storage area should be clean, cool, dry and ventilated.
