About the DALY Smart Active Balancer 1A

The DALY Smart Active Balancer 1A is a compact battery balancing module designed to keep every cell in multi-cell Li-Ion and LiFePO4 packs at the same voltage. This active battery balancing system moves charge between cells at up to 1 A, working quietly in the background to extend battery life, improve performance, and increase pack safety.

Key Features

  • 1A Active Balancing

    Transfers up to 1 amp between cells to correct imbalance faster than passive methods and prevent weak cells from limiting pack capacity.

  • Smart Battery Balancer Technology

    Real-time voltage sensing redirects current only where needed to avoid overcharge and undercharge across the pack.

  • Compact Battery Pack Balancer

    Slim 80 × 50 × 8 mm PCB fits inside most battery enclosures without taking extra space.

  • Advanced Lithium Battery Balancing

    Compatible with Li-Ion and LiFePO4 cell chemistries across 4S to 20S configurations for flexible integration.

  • Battery Health Monitoring

    Built-in LED indicators show balancing status. LEDs glow green when cells are equal and red if a problem is detected.

  • Smart Energy Management

    Low self-consumption under 2 mA prevents the balancer from draining the battery when the pack is idle.

  • Optional Data Logging

    CAN and UART ready for integration with battery management systems, data logging, and diagnostics.

Benefits of Using a Battery Equalizer for EVs and Energy Storage

  • Longer Battery Life

    Balanced cells age more uniformly so no single cell fails early and the overall pack lifespan increases.

  • Improved Pack Performance

    Even cell voltages mean the pack can deliver consistent power under load for better vehicle acceleration and smoother device operation.

  • Enhanced Safety

    Active balancing reduces the risk of individual cell overvoltage and deep discharge, improving operational safety for EV and storage systems.

  • Easy Integration

    Clear wiring labels and four mounting holes make installation fast and repeatable for OEMs and DIY projects.

How the DALY Smart Active Balancer 1A Works

The balancer continuously monitors each cell voltage and moves small amounts of charge from higher-voltage cells to lower-voltage cells at up to 1 A. This active cell balancing keeps the pack voltage window narrow so the pack delivers steady power and no single cell is overstressed.

Typical Use Case

In an electric bicycle with a 10-cell pack, the balancer prevents one cell from overcharging while another is low. The result is a stable pack that climbs hills and accelerates reliably.

Install and Configure

  1. Mount the Balancer: Secure the PCB inside the battery enclosure with the four M3 screws.
  2. Connect Cell Leads: Attach each balance wire from cell 1 up to cell 20 into the clearly labeled ports.
  3. Hook Up Pack Leads: Connect the main B+ and B- pack wires to the balancer.
  4. Power On and Test: Apply a small charge or load and verify LEDs. Solid green indicates balanced cells and healthy operation.

Applications

  • Electric vehicles – e-bikes, e-scooters, go-karts, golf carts
  • Residential and commercial energy storage systems and solar battery banks
  • DIY powerwalls and backup UPS systems
  • Portable power stations for camping and job sites
  • Custom EV and battery maintenance projects

Sensory Experience

  • Feel – A slim, smooth PCB that is light and easy to secure inside enclosures.
  • See – LEDs blink softly at 1 Hz during balancing and remain solid green when cells are equal.
  • Hear – Silent operation. No fans and no audible noise while balancing.

User Story

Maya built a 12S LiFePO4 solar charger and used the DALY Smart Active Balancer 1A to keep her cells equal. The balancer corrected imbalances quietly, the LEDs confirmed healthy cells, and her system performed reliably on every trip.

Buy with Confidence
