Sunkko Active Balancer D2524C+ 20A 2-24S

SUNKKO ACTIVE BALANCER D2524C+ 20A 2-24S

The SUNKKO D2524C+ is a professional multi-channel lithium battery equalization and analysis machine for battery modules from 2S up to 24S. It is designed for service centres, battery rebuilders, EV workshops, energy-storage maintenance teams and production environments that need to observe the voltage behaviour of many series-connected cell groups while carrying out controlled equalization work. Rather than treating imbalance as a single-cell problem, the machine gives the operator a system-level view of a multi-series pack and provides a dedicated platform for bringing cell-group voltages closer together.

The D2524C+ belongs to SUNKKO's high-current equalizer/analyzer family and is positioned above small PCB-style active balancers. It is intended for workshop use where the battery can be connected to a dedicated service machine for monitoring, balancing and diagnostic work.

A multi-channel equalizer works by connecting separately to the series points of the battery module so that the machine can collect voltage information for each connected group. The control system can then manage charge/discharge equalization activity across the connected channels while the operator monitors the changing voltage relationship between groups. This makes the machine useful for identifying large voltage spread, verifying whether equalization is progressing and preparing repaired or matched modules for further testing.

The 24-channel architecture is important because it allows the same service platform to cover a broad range of battery configurations up to 24S. High-current equalization equipment is normally selected for larger modules where low-current balancing would take longer to correct a substantial voltage difference. The machine should be considered a service and maintenance tool rather than a replacement for the pack's BMS, charger or final safety validation process.

Use the D2524C+ only with battery configurations and chemistries supported by the machine's operating instructions. Confirm the number of series groups, cell-voltage range, harness sequence and polarity before connection. For packs using a BMS, the service procedure should account for the BMS wiring and protection logic rather than bypassing it blindly. The supplied SKU name identifies a 2–24S model; the exact current rating should be matched to the nameplate of the stocked machine before publishing or commissioning because SUNKKO currently lists a D2524C+ 24-channel variant at a different current value on its official product family page.

Applications

1. EV battery module balancing and maintenance

2. Lithium battery repair and refurbishment workshops

3. Energy-storage module servicing

4. Battery production and quality-control support

5. Multi-series battery pack diagnostics

6. R&D and engineering evaluation of cell-group voltage balance

Installation Guide

Place the machine on a stable bench with adequate ventilation and keep the battery in a safe service area. Identify every cell-group tap before connecting the balance harness, then verify the voltage progression with a meter. Connect the negative reference and series points in the exact order specified by the machine documentation. Set the operating parameters for the battery chemistry and required service procedure before starting equalization. During operation, monitor cell-group voltage behaviour and battery temperature, and stop the process if the pack shows abnormal heating, damaged wiring or unstable voltage. Disconnect the pack only after the machine has completed or safely stopped the active process.
