Characteristics
At 25±5°C discharge the battery with the current of
0.33C to the cut-off voltage and record charge
capacity. Store the battery at various temperatures
for 2h and discharge the battery with 0.33C to the
cut-off voltage.

Discharge with the current of 0.33C until it can’t
discharge, and then rest it for 1h. Charge the battery
following CC (1C)/CV (43.8V) mode to full capacity,
and then rest it for 1h. Repeat above process until full
charged capacity is no more than 80% of normal
value. Accumulated times is defined as cycle life.

capacity ≥90%
Rest for 1 hour after fully charged, then discharge with
0.33C current until the battery reaches the discharge
cutoff voltage. Repeat above process for three times,
if the discharge time is not less than 180 minutes, you
can stop and define the Discharging current*time
value (Ah) as battery capacity.
