Daly 15S 1 A BMS Smart Active Balancer with Bluetooth for Li-ion and LiFePO4 Batteries 65 x 115 x 19 mm Red Home and Solar Storage
You already have the maximum available quantity in your cart.
This smart active balancer from Daly balances the voltage of individual cells in 15S batteries and offers wireless connectivity via Bluetooth with status monitoring in a mobile app. Active balancing, unlike passive, does not dissipate excess energy as heat but transfers it 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 1 A and supports Li-ion, LiFePO4, and LTO batteries. In addition to wireless connectivity, it also offers RS485 and UART communication interfaces for integration into superior systems and monitoring. The compact body in red with an LED indicator can be easily placed directly next to the battery pack without complicated installation.
Key Features:
- Active Balancing — energy is transferred between individual cells, ensuring that the voltage remains even across the entire 15S assembly and the battery is fully utilised.
- Bluetooth Connectivity — the included module allows monitoring of the voltage and status of individual cells directly in the mobile app.
- Balancing Current — a maximum current of 1 A ensures effective balancing even among cells with larger voltage differences.
- Wide Compatibility — the balancer is suitable for Li-ion, LiFePO4, and LTO batteries with various nominal voltages.
- Communication Interfaces — RS485 and UART allow connection with other devices and control systems.
- Compact Dimensions — the body size of 65 x 115 x 19 mm fits even in cramped spaces next to the battery.
- LED Indication — a green indicator on the body signals that the device is operational.
- Red Housing — a sturdy plastic cover protects the internal electronics from damage.
Package Contents:
- 1x Daly 15S Smart Active Balancer
- 1x Bluetooth Module
The balancer is suitable for home and solar energy storage and smaller battery assemblies with fifteen cells in series. Regular voltage balancing helps extend battery life and protects individual cells from overcharging and excessive discharging. Thanks to Bluetooth connectivity and the mobile app, you have an overview of the status of individual cells at your fingertips. Support for Li-ion, LiFePO4, and LTO chemistry, along with RS485 and UART interfaces, ensures wide applicability in various types of battery systems. Automatic operation does not require complex settings and keeps the cells consistently balanced even during regular daily use.
