DALY Smart BMS 4S 12 V 60 A Bluetooth Balancer and NTC Sensor 65 x 123 x 14 mm for LiFePO4 Batteries Red Caravans and Photovoltaics
You already have the maximum available quantity in your cart.
The DALY Smart BMS is an intelligent protection board for constructing lithium batteries LiFePO4. It is designed for 4S LiFePO4 batteries with a voltage of 12 V and can handle continuous charging and discharging current of 60 A with overcurrent protection at 90 A. The battery status can be monitored wirelessly via the included Bluetooth module in a mobile application. The internal resistance of the circuit is less than 20 mΩ, which increases efficiency and reduces heating. The compact board with dimensions of 65 x 123 x 14 mm easily fits into smaller assemblies.
The built-in passive balancing with a current of 100 mA equalises the voltage of individual cells and increases usable capacity and battery life. The board protects the cells from overcharging with a threshold of 3.75 V and deep discharge with a threshold of 2.2 V, overcurrent, and short circuits. The included NTC sensor takes care of temperature measurement, and the package also includes a Bluetooth module. Low standby consumption of under 550 µA ensures minimal self-discharge of the connected battery.

This protection board represents a practical solution for assembling 12V LiFePO4 batteries for caravans, photovoltaics, and home energy storage. It can also be used in electric vehicles, tricycles, forklifts, and golf carts. The balancer and multi-level protection extend the lifespan of the cells and enhance the safety of the assembly. Reliable operation is ensured over a wide range of operating temperatures from -35 to 75 °C. The included Bluetooth module, temperature sensor, and connecting cables allow for immediate setup without the need for additional accessories.
