CELL TESTING MACHINE (EST-BP100V20A-2CH)

EST BP 100V 20A-2CH Portable Battery Pack Charge-Discharge and Balancing Tester

The EST BP 100V 20A-2CH is a portable battery pack charge-discharge tester with balancing functionality and two main test channels. Its main pack-testing range is 5-100V, with a 20A current class for compatible batteries and approved test procedures.

The instrument combines electrical pack evaluation with a balancing function in a movable test format. It should be selected as a pack-testing system, not assumed to be a universal single-cell tester simply because the catalog uses the term cell testing machine. The main pack connection and any cell-level balancing connections serve different purposes.

Controlled charge and discharge testing allows a technician to evaluate pack behaviour under a defined procedure. The 20A class identifies an equipment current capability, not a recommendation for every battery. Set the actual current and termination conditions from the pack requirements and confirm that the BMS and test connections support them.

Balancing is a separate function intended for compatible pack arrangements. It does not reverse physical cell deterioration or guarantee recovery of the battery's original capacity. Investigate the cause of an imbalance and assess cell condition before deciding that balancing is an appropriate action.

Keep the operating ranges of the main pack terminals and balancing connections distinct. A cell-level connection must never be treated as an alternative high-voltage pack input. Use the correct manufacturer-approved harness and connection procedure for the exact instrument configuration.

Compare the pack's maximum charged voltage and required discharge endpoint with the 5-100V main-port range. A series-count label by itself is insufficient because different cell chemistries and charge limits produce different pack voltages. Confirm the permitted charge and discharge current as well as the connector arrangement.

For balancing work, provide the cell chemistry, series count, access arrangement and required harness details. Verify the delivered balancing configuration rather than assuming that every version has identical current capability. Also define whether the station needs capacity evaluation, maintenance diagnosis or development testing, since each purpose requires its own method and acceptance criteria. Portability makes relocation practical but does not remove the need for an appropriate test area.

Applications

• Controlled charge-discharge evaluation of compatible packs.

• Pack-capacity checks using an approved test procedure.

• Balancing evaluation with the correct cell-access harness.

• Battery development and technical-service workstations.

• Comparison of pack behaviour before authorised maintenance decisions.

Installation Guide

Have trained personnel install and commission the tester with the specified supply, protective earth and approved pack connections. Establish a stable work surface and protect all exposed battery conductors. Follow the instrument manufacturer's connection order and isolation instructions, especially when attaching balancing leads.

Start with a known, approved pack and verify the limits before carrying out a complete test. Label main and balancing connections clearly so that they cannot be confused. Inspect leads and harnesses before use, keep records of the selected procedure and stop when abnormal behaviour is observed. Do not use balancing as a workaround for damaged cells or an unresolved pack fault.

Why Choose ARB Accessories?

ARB Accessories brings together pack-testing equipment, BMS products, wiring, connectors and battery-assembly components for Indian manufacturers. Share the pack voltage limits, intended test current, connector arrangement and required reports when enquiring about this model. Reviewing the complete test connection and workflow helps distinguish a suitable production tester from a machine selected only by its maximum current rating.
