China Factory Lithium 25.6V 55ah LiFePO4 Battery for Solar Street Light

 


 

Technical advantages

 


 
High cycle life and deep cycle ability   More usble capacity
     
Great deep cycle ability provides highly efficient cycling and float service with great energy density, increases overall efficiency.   LFP provides 100% of usable energy, so that you can discharge the battery entirely without causing downtime of your solar street light, ensures reliability of the operation.
     
 
Superior  temperature performance   Easy installation
     
Excellent high temperature performance makes these batteries easily superior than VRLA, can work in up to 60°C temperature. Whereas at 60°C VRLA batteries can hardly operate normally.   These batteries are designed to be drop-in replacement for sealed lead acid batteries without additional labor cost. Also can be installed inside the pole which saves costing for separate cabinet.
     
     
 
Anti theft   User friendly BMS
     
Small footprint, compact and light battery, can be stored inside the pole or on the top of the pole, not easy to steal like VRLA batteries;   User friendly BMS monitors and communicates regarding the SOC, SOH, protects the system from short-circuit, high and low discharging and charging, high temperature etc.The battery supports bluetooth monitoring feature (optional) for worry free operation.
