Get the most out of your lithium batteries with the Daly BMS active balancer, designed to extend battery life, improve performance, and ensure stable power distribution. Whether you’re using 18650 battery packs or Lifepo4 systems, this intelligent battery equalizer automatically balances voltage across cells to prevent overcharging, undercharging, and capacity loss. Built for DIY battery projects, solar energy setups, and e-bike systems, it’s the essential tool for keeping your batteries performing at their best.

Key Features

  • High-efficiency 5A active balancing current ensures rapid and even voltage equalization.

  • Supports multiple configurations: 3S, 4S, 8S, 10S, 13S, and 16S lithium battery packs.

  • Reduces energy loss and extends battery life by preventing cell imbalance.

  • Compact, lightweight design with high-quality PCB for durability and heat resistance.

  • Compatible with both 18650 and Lifepo4 battery systems.

Why Choose Our Daly BMS Active Balancer
Unlike traditional passive balancers that waste energy as heat, the Daly BMS 5A balancer redistributes excess energy efficiently between cells. This smart energy transfer technology not only preserves power but also maintains consistent cell voltage — crucial for long-term reliability. Trusted by battery builders and energy enthusiasts, it’s a cost-effective upgrade for any lithium battery setup.

Perfect For

  • DIY lithium battery builders and hobbyists.

  • E-bike, e-scooter, and electric tool battery systems.

  • Solar energy storage and off-grid applications.

  • Powerwall and backup energy setups requiring stable voltage performance.

How It Works
Connect the balancer’s wires to your battery pack’s balance leads. The active system detects voltage differences between cells and transfers energy from higher-voltage cells to lower ones until equilibrium is reached.

Extend Battery Life & Performance
Maximize efficiency, reliability, and safety with the Daly BMS Active Balancer — the smart solution for maintaining perfectly balanced lithium battery packs.

    Beautiful dress
    Really happy with this purchase. I only wish I had steamed it before trying it on because it arrived with a few wrinkles from shipping.

    Worth every dollar
    The quality surprised me. The material has a nice weight and doesn't feel see-through at all. I'll definitely order another style.

    Runs slightly roomy
    I was between sizes and ordered the larger one. It still looked great, but I probably could have gone with my usual size.
