You already have the maximum available quantity in your cart.
The DALY Smart BMS is an electronic protection and control module designed for lithium iron phosphate (LiFePO4) batteries in a 4S configuration with a nominal voltage of 12 V. The module is designed for continuous charge and discharge currents of up to 500 A, making it suitable for energy-intensive applications, such as solar systems, backup power sources, or drive batteries. With the integrated Bluetooth connection, you can conveniently monitor and configure the battery status directly from a mobile application without needing to physically access the module. The included NTC sensor continuously monitors the temperature of the cells, and the UART communication interface allows connection to other devices and control units. The compact metal design facilitates installation in battery boxes and custom assemblies while also aiding in heat dissipation.
Main Features:
- High Current — the module handles charge and discharge currents of up to 500 A and protects the battery from overload
- 4S Configuration — designed for LiFePO4 batteries with a nominal voltage of 12 V
- Bluetooth Control — wireless monitoring of voltage, current, and battery status via a mobile application
- NTC Sensor — continuous temperature measurement of the cells during charging and discharging for enhanced safety
- UART Interface — connection to other devices, displays, and control units
- Active Cooling — integrated fan dissipates heat even under prolonged loads
- Compact Dimensions — 108 x 183 x 26 mm allows for easy placement in battery assemblies
- Red Metal Body — durable construction with a metal heatsink
Package Contents:
