Description
Our Lithium Battery Equalizing Tester Series includes professional battery maintenance equipment designed for lithium battery cell testing, balancing, activation, and maintenance. The equipment supports constant current charging, constant voltage charging, constant current discharging, and constant power discharging.
These testers are widely used for:
- Battery cell balancing after battery pack replacement
- Battery capacity grading and screening
- SOC balancing before battery pack assembly
- Routine maintenance of lithium battery packs
- Battery performance testing and lifecycle testing
With high-precision voltage and current control, the equalizing tester ensures each battery cell operates within safe limits, improving battery pack consistency and extending overall battery service life.

Functional Characteristics
• Various kind of maintenance modes:
replenishment, discharging and equalizing , which is convenient to use in different working conditions.
• Battery testing template presetting:
covers the maintenance of mainstream lithium batteries in the market.
• High performance equalizing:
the maintenance process supports end depolarization, which guarantees a highly consistent effect after equalization.
• Independent channels design:
without interfering with each other, ensuring that each battery cell will not be over-charged & discharged.
• Compact size:
Easy to carry, the equipment supports 1~6 channels to expand, and a single channel supports 12 strings of battery cells’equalization at the same time.
Unique Advantage
