FT1900 Series is a lithium iron phosphate battery that offers multiple energy storage options through an expandable modular design (3-5 modules combined), which further simplifies installation and O&M with multiple smart functions.
FEATURES:
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 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.
