Lead Acid Replacement

Lithium Iron Phosphate Battery

LP15-12200 (12.8V/200Ah)

With smart design and elegant appearance, MUST LiFePO4 battery is an ideal replacement for traditional lead acid battery,offering a drop-in solution for lead acid battery replacement. Our battery can be used individually or assembled in series to create larger system.


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

Suitable applications include:

•Golf Car
•Solar Storage
•Remote Monitoring
•Switching applications and more


High cycle life

4000 cycles @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.


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


•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.
