Battery string 614.4V 126AH
Battery Cabinet 614.4V 1008AH
Longer Cycle Life : Offers up to 20 times longer cycle life and
five times longer float/calendar life than lead acid battery ,
helping to minimize replacement cost and reduce total cost of
ownership
Lighter Weight : About 40% of the weight of a comparable lead acid
battery . A " drop in" replacement for lead acid batteries
Higher Power : Delivers twice power of lead acid battery ,even high
discharge rate, while maintaining high energy capacity
Wider Temperature Range : -20℃~60℃
Superior Safety: Lithium Iron Phosphate chemistry eleminates the
risk of explosion or combustion due to high impact overcharging or
short circuit situation

FAQ
Q: LiFePO4 cells are rated for charging down to 0°C. What is the
result of charging below this temperature?
A: This is not allow to charged below 0°C. Under low temperature
charging, the Lithium simplex deposits, impaired cycle life and
increased risk of thermal runaway.
Q: At what temperature is the performance reduced, and at what
temperature does permanent damage result?
A: The best operation temperature is 25℃, the battery performance
is affected to different degrees under other temperature,especial
low temperature. Low temperature affects positive and negative
electrodes, electrolyte and adhesives of LiFePO4 batteries.
As the temperature decreases, the average discharge voltage and
discharge capacity of the lithium-ion battery decrease. Especially
when the temperature is -20 ° C, the discharge capacity and average
discharge voltage of the battery decrease rapidly.
Less than -20℃ and higher than 70℃ operating will cause the
permanent damage. Please follow the operating temperature as below:
Charge: 0~45℃, Discharge: -20~60℃
Q: What are the cell matching procedures used by the Huaxing to
provide matched sets of cells to be assembled into battery packs?
A: Capacity, IR, voltage
