Daly 3S 5 A BMS Smart Active Balancer for Li-ion and LiFePO4 Batteries with Cell Balancing 97 x 65 x 21 mm Red Solar Storage
You already have the maximum available quantity in your cart.
This smart active balancer from Daly equalises the voltage of individual cells in 3S Li-ion and LiFePO4 batteries. Unlike passive balancing, which dissipates excess energy as heat, active balancing transfers energy from more charged cells to less charged ones, keeping the entire battery pack balanced and reducing losses. The balancer operates with a maximum balancing current of 5 A, allowing for quicker equalisation even with larger voltage differences between cells. Its compact body in red with an LED indicator can be easily placed directly next to the battery pack without complicated installation. The higher balancing current is particularly appreciated in larger battery assemblies for both home and solar energy storage.
Key Features:
- Active Balancing — energy is transferred between individual cells, ensuring even voltage across the entire 3S assembly and maximising battery usage.
- Balancing Current — a maximum current of 5 A ensures quick and effective equalisation even for cells with larger voltage differences.
- Wide Compatibility — the balancer works with both Li-ion and LiFePO4 batteries, which differ in nominal voltage.
- Hardware Active Balancing — operates fully automatically without the need for programming or connection to an app.
- LED Indication — a green indicator on the body signals that the device is operational.
- Compact Dimensions — the body size of 97 x 65 x 21 mm fits into tight spaces next to the battery.
- Red Housing — a sturdy plastic case protects the internal electronics from damage.
- Easy Connection — the included cable simplifies the connection of the balancer to the terminals of individual cells.
Package Contents:
- 1x Daly 3S Smart Active Balancer
- 1x Cable
The balancer is suitable for installation in home backup power sources for solar systems and battery assemblies with three cells in series. Regular voltage balancing helps extend battery life and protects individual cells from overcharging and excessive discharging. With compact dimensions of 97 x 65 x 21 mm, it can easily be integrated into most assemblies, even into smaller boxes. The higher balancing current of 5 A reduces the time needed to equalise cells and keeps the pack consistently balanced. The combination of support for Li-ion and LiFePO4 chemistry ensures broad applicability across various types of battery systems.
