04 Strict quality inspection | ||
Comprehensive peformance test for the semi-finishedbattery: battery activation test, open circuit voltage test, AC internal resistance test, dishcarging & charging test. | Aging test for the finished battery pack: sitimulate real usage with continuous charge-discharge cycles to assess life and performance. |
Battery vehicle load test: each battery undergoes loeading, stability, and power testing before packaging and shipping. |
1. Measure the battery compartment dimensions | 2. Check the controller's voltage & current, rated power of the motor |
3. Assess the capacity you need |
3. Confirm the charge & discharge interface type and form you need |
