Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Work Procedure
- CHECK ADJUSTMENT VOLTAGE VALUE
With CONSULT
- Power switch ON.
- Select "DATA MONITOR" mode.
- Check "MAXIMUM CELL VOLTAGE".
- Double the "MAXIMUM CELL VOLTAGE" and use that value as the module adjustment value.
Adjustment voltage value: MAXIMUM CELL VOLTAGEx 2
Example: 3.925 V (MAXIMUM CELL VOLTAGE) x 2 = 7.850 V (Adjustment voltage value)
GO TO 2.
- CHECK MODULE VOLTAGECAUTION:
- This operation must be performed in an ambient temperature of 0 to 40°C.
- For details on the module charge balancer operation, refer to the adjuster operation instructions.
- Set the new module to the module charge balancer.
- Measure module voltage and compare it with "adjustment voltage value" confirmed in STEP1.
Module voltage is lower than adjustment voltage value GO TO 4.
Module voltage is higher than adjustment voltage value GO TO 3.
- DISCHARGE OF MODULE VOLTAGECAUTION:
- This operation must be performed in an ambient temperature of 0 to 40°C.
- For details on the module charge balancer operation, refer to the adjuster operation instructions.
Discharge the module to 5.0 V using module charge balancer.
Discharge voltage: 5.0 V
GO TO 4.
- MODULE VOLTAGE ADJUSTMENTCAUTION:
- This operation must be performed in an ambient temperature of 0 to 40°C.
- For details on the module charge balancer operation, refer to the adjuster operation instructions.
- Enter the "adjustment voltage value" in the module charge balancer.
Adjustment voltage value: MAXIMUM CELL VOLTAGEx 2
- Start the voltage adjustment.
After module voltage adjustment, GO TO 5.
- CHECK MODULE VOLTAGE
- Remove the module from the module charge balancer.
- Using a circuit tester, check that the module voltage is within the specified range.
Standard: Adjustment voltage value ± 10 mV
GO TO 6.
- CHECK CELL VOLTAGE
With CONSULT
- After adjusting the voltage, install the module to the vehicle.
- Select "DATA MONITOR" mode.
- Check "CELL VOLTAGE" of install module.
- Check that the difference from the "MAXIMUM CELL VOLTAGE" confirmed in Step1 is within the specified range.
Standard: MAXIMUM CELL VOLTAGE ± 33 mV

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
