FEATURES & BENEFITS

High cycle life

1500 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.

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.
