NEEY ACTIVE BALANCER 23S/24S 2A

NEEY ACTIVE BALANCER 23S/24S 2A

The NEEY 23S/24S 2A active balancer is a cell-equalization module for battery projects using 23/24 series-connected cell groups. It helps reduce differences between cell-group voltages through active energy transfer. This 23S/24S configuration gives battery builders a defined series format and a 2A balancing-current class for selecting the equalizer alongside the rest of the pack hardware.

Active balancing redistributes stored energy between cell groups. More even charge levels can help the pack use capacity that would otherwise be limited by one group reaching its cut-off earlier than the others. The 2A designation refers to balancing current, not the current carried by the pack's main power cables. Balancing speed depends on operating conditions, cell capacity and the amount of imbalance; a current class alone does not specify a fixed completion time.

In a 23S/24S pack, the balancer connects across 23/24 successive cell groups. Each group may contain parallel cells, but the series count stays 23/24. Choose the balancer by this series layout, not by the total number of individual cells. Match the board to the cell chemistry and operating-voltage range specified for the supplied revision. Use a dedicated BMS for charge, discharge and fault protection. Persistent voltage drift also calls for checks of cell condition, contact resistance and charger settings, rather than relying on equalization alone.

Applications

• Battery builds using the 23S/24S series format

• Compatible solar or backup storage assemblies

• Pack maintenance after cell and connection checks

• Custom battery projects needing 2A-class equalization

Installation Guide

Follow the connection diagram for the actual board. Keep the harness disconnected from the module while connecting the cell taps, and meter-check the tap order before insertion. Mount the board with electrical insulation and adequate clearance. Secure the leads, start under controlled conditions and check the cell-group voltages before closing the enclosure.
