2.3 Warranty Cycle Capacity

When the battery system has not reached the limit of service life and cycle life, but the total

discharge capacity of the battery meets the following parameters, the warranty responsibility

of GT Powertank will also be terminated. (Using conditions DOD80%, working environment

system.

3. Testing Method:

A. Discharge at a rate of 0.5C until the total voltage of the battery reaches 44.8V(GL48100),

and the discharge ends;

B. Rest 0.5h;

C. 0.5C rate constant current charging to the total battery voltage of 55.2V (GL48100), and

then 55.2V (GL48100) constant voltage charging until the charging current is less than or

equal to 0.05C, the charging ends;

D. Rest 0.5h;

E. Discharge at a rate of 0.5C until the total voltage of the battery reaches 44.8V (GL48100),

and the discharge ends;

F. Rest 0.5h.

Repeat steps C-F for a total of 3 times, and take the average value of the discharged power.

Note: The end-of-discharge voltage 44.8V (GL48100) is the protection voltage designed for
