Product Specification

content Testing method Remark

Charge cut-off voltage

Discharge cut-off voltage
Standard charge Under the condition of the ambient temperature of 25 ± 2 ℃ , Charge the battery at constant current of 0.2C to reach 42V. Then charge the battery at constant 42V voltage until the charging current decreasing to 0.02C.  
Standard discharge After the standard charging , rest for 1 hour then discharge to 27.5V@0.2C.
