70V-5A CHARGE 10A DISCHARGE

70V-5A CHARGE 10A DISCHARGE

The 70V 5A Charge / 10A Discharge unit is a battery-pack testing and aging system intended for controlled charge-discharge evaluation of finished lithium battery packs. The product class is commonly used after battery assembly to check capacity, charging behavior, discharge behavior and BMS cutoff performance under a defined test program. Its key electrical limits are a 70V voltage class, charging current up to 5A and discharge current up to 10A.

For battery manufacturers and repair workshops, controlled cycling provides more useful information than checking pack voltage alone. A pack can show the expected open-circuit voltage while still having reduced usable capacity, an early BMS cutoff, a weak series group or excessive voltage sag under load. Charge-discharge equipment allows these conditions to be observed in a repeatable workshop process.

This battery testing machine is configured for controlled testing of battery packs up to the 70V class, with charging current up to 5A and discharge current up to 10A. During capacity and aging work, the tester applies controlled charge and discharge cycles so technicians can evaluate delivered capacity, discharge behaviour and pack consistency under repeatable conditions.

The charge and discharge ratings describe the capability of the test equipment, not the maximum real-world current capability of the battery being tested. A high-power traction or energy-storage battery can still be evaluated at a lower controlled current when the goal is capacity comparison, cycle testing or quality inspection. Consistent test settings, secure high-current connections and accurate cutoff parameters are important for producing comparable results from one pack to another.

Select the tester only for battery packs whose operating voltage remains within the machine's verified range. Confirm the battery chemistry, charge cutoff, discharge cutoff and BMS architecture before starting a test. The machine should also be checked for compatibility with common-port versus separate-port BMS wiring. If production requires multiple channels, PC networking, barcode input or automated data export, verify those functions on the exact machine rather than assuming every 70V tester includes them.

Applications

1. Finished lithium battery pack capacity testing

2. Charge/discharge aging and cycle testing

3. BMS charge and discharge cutoff verification

4. EV battery pack quality control

5. Energy-storage and backup battery inspection

6. Battery repair, refurbishment and production-line testing

Installation Guide

Operate the tester in a dry, ventilated technical area with correctly rated power and cables. Confirm polarity before connecting a battery, then set charge voltage, charge current, discharge cutoff and discharge current according to the pack specification. Start with conservative settings on an unknown or repaired battery and monitor temperature and cell behavior through the BMS or external measurement system. Keep battery packs separated from combustible materials during controlled cycling and never exceed the test equipment's voltage or current limits.

Why Choose ARB Accessories?

ARB Accessories focuses on lithium-battery, EV, energy-storage and battery-pack assembly components for Indian B2B and technical buyers. The catalog brings together battery cells, BMS boards, connectors, nickel strip, wiring, testing equipment and production machines in one specialist range, which helps workshops, pack builders, system integrators and OEM teams compare related components in one place. For technical products, ARB should be selected on the basis of the exact model, electrical rating, connector format and application requirement rather than generic marketing claims. Final compatibility should always be checked against the battery design, machine model and installation conditions before use.
