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.
