18650 2.2Ah cylindrical li-ion battery cells offered by esdTronix are ensured with the full capacity and discharge performance. The discharge performance was inspected under different temperatures to make sure the users can get a higher consistency at the same working temperature! After 300/400/500/800/1000 cycles in 100% DOD charge and discharge at 0.5CA current, the residual discharge capacity is above 80% of the initial capacity (the cycle life will be longer if compared with the nominal capacity or the capacity retention is requested to be less than 80%). The cut-off voltage of discharge is 2.75V(2.5V is an over-discharge voltage which will damage the cell ).
