DALY SMART ACTIVE BALANCER 23S 1A

DALY SMART ACTIVE BALANCER 23S 1A

The DALY SMART ACTIVE BALANCER 23S 1A is a DALY smart active battery balancer designed for 23S lithium battery packs with a 1A balancing-current class. It targets buyer searches such as DALY 23S 1A active balancer, 23S battery equalizer, 1A smart cell balancer, lithium battery active balancing module and is used where series-connected cells or cell groups need active equalization rather than simple passive bleed balancing. In a multi-series pack, small differences in cell capacity, state of charge and internal resistance can cause voltage spread to increase over time, especially after repeated cycling.

Active balancing transfers energy between cell groups to reduce that spread and help more of the pack operate within a similar voltage window. It is a pack-maintenance and consistency tool, not a replacement for a correctly specified BMS, charger, fuse or properly matched cells. A damaged or internally shorted cell cannot be corrected by balancing and should be diagnosed separately.

The 23S rating defines the maximum series-group architecture for this balancer, while the 1A rating describes the balancing-current class. DALY publishes a Smart Active Balance Module family and 1A active-balancing documentation, which supports the way buyers commonly search for a DALY active balancer, smart battery equalizer, lithium cell balancer and battery pack balancing module. The practical value of active balancing is highest when the pack is electrically healthy but develops moderate cell-voltage divergence because of normal cell variation, aging or unequal state of charge.

Balancing current should not be confused with charge or discharge current through the battery pack. The balancer works on the cell-group voltage relationships, while the main BMS and power wiring control the traction or inverter current path. Correct harness order is critical because the module measures multiple cell taps at different potentials; a reversed or misplaced lead can damage the balancer or create a short-circuit path.

Match the balancer to the actual series count, battery chemistry, cell-voltage range, balance-harness arrangement and communication/accessory package used in the pack. For a 23S build, confirm that every sense lead maps to the intended cell group before the connector is inserted. Choose active balancing when the pack design benefits from energy transfer between groups; if the problem is a weak, damaged or capacity-mismatched cell, cell testing and replacement may be required instead. Allow enough enclosure space for the module, harness bends and insulation so the wiring cannot be crushed by the lid or battery compression hardware.

Applications

• 23S lithium battery-pack cell equalization.

• Electric scooter, e-bike and EV battery maintenance.

• Solar inverter and stationary energy-storage packs.

• Battery refurbishment and cell-matching workshops.

• Custom lithium battery prototyping and diagnostic builds.

Installation Guide

Disconnect the charger, load and any external communication accessories before installing the balancer. Measure the pack and each series group first, then connect the balance leads in the exact sequence shown for the module. Keep loose metal tools away from exposed cell terminals and insulate unused conductors. Do not plug or unplug the harness under a known fault condition or while the pack is being charged at high current. After installation, check the reported cell voltages against a meter and observe balancing behaviour before returning the battery to normal service.
