Daly 3S 1 A BMS Active Balancer for Li-ion and LiFePO4 Batteries with Active Cell Balancing 35 x 60 x 18 mm Red Home Solar Storage
You already have the maximum available quantity in your cart.
This hardware active balancer from Daly is designed to equalise the voltage of individual cells in 3S Li-ion and LiFePO4 batteries. Active balancing, as opposed to passive, does not dissipate excess energy as heat but transfers it from more charged cells to less charged ones, thereby keeping the entire battery pack balanced and reducing losses. The balancer operates with a maximum balancing current of 1 A and is intended for assemblies with three cells in series, which are used in both home and solar energy storage systems. Its compact body in red with an LED indicator can be easily placed directly onto the battery pack without complicated installation. The package also includes a connecting cable for quick and clear connection to individual cells.
Key features:
- Active balancing — energy is transferred between individual cells, ensuring that voltage remains even across the 3S assembly and the battery is fully utilised.
- Balancing current — a maximum current of 1 A ensures effective balancing even with cells that have a larger voltage difference.
- 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 top signals that the device is operational.
- Compact dimensions — body size of 35 x 60 x 18 mm fits even in cramped spaces next to the battery.
- Red casing — sturdy plastic cover 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 active balancer
- 1x cable
The balancer is suitable for installation in home backup sources of solar systems as well as smaller 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 35 x 60 x 18 mm, it can be easily integrated into most assemblies and smaller boxes. Automatic operation requires no settings or maintenance and keeps the cells continuously balanced. The combination of support for Li-ion and LiFePO4 chemistry ensures wide applicability in various types of battery systems and helps maintain higher available capacity of the entire pack over time.
