DALY SMART ACTIVE BALANCER 17S 1A

DALY SMART ACTIVE BALANCER 17S 1A

The DALY 17S 1A smart active balancer provides active cell equalization for a battery pack with 17 series-connected cell groups. It helps keep cell-group voltages closer together by redistributing energy within the pack. Smart control makes this model useful where balancing settings and cell information form part of the battery commissioning workflow.

The balancing circuit operates at up to 1A. This is the equalization-current rating, separate from the current supplied to an inverter, motor or other load. A pack can lose usable capacity when one group reaches its voltage limit ahead of the others. Active balancing addresses charge differences between groups, while cell condition and connection quality still determine the underlying pack performance. Smart functions are accessed through the supported DALY communication arrangement.

In a 17S pack, the balancer connects across 17 successive cell groups. Each group may contain parallel cells, but the series count stays 17. Choose the balancer by this series layout, not by the total number of individual cells. Match the unit to the battery chemistry, full operating voltage and BMS series count. Use the communication accessories specified for that DALY revision. The module complements the pack's BMS; charge, discharge, temperature and short-circuit protection remain responsibilities of the protection system.

Applications

• 17S lithium battery pack integration

• Compatible inverter and solar storage batteries

• Cell-voltage checks during pack commissioning

• Battery service projects requiring active equalization

Installation Guide

Use the wiring sequence supplied with the unit. Attach and meter-check the sampling leads before plugging them into the balancer. Secure the module on an insulated mounting surface and keep connectors accessible for service. Where a supported interface is used, check cell readings and balance settings against the pack design before the first controlled charge cycle.
