Product Overview

Highlights

Powerful Protection Function: The BMS offers a robust range of protection features, including overcharge protection, over-discharge protection, overcurrent protection, short circuit protection, and temperature protection. These ensure the battery pack is safe from damaging conditions, enhancing the longevity and performance of the cells. 【Note】Hardware BMS dosen't have communication functions.
Other Protective Functions: The BMS is built with dust-proof, shockproof, and anti-squeezing features, making it more durable and capable of withstanding harsh environmental conditions. This adds an extra layer of protection, ensuring the BMS continues to function effectively even in challenging situations, such as vibration, dust, or physical pressure.
Wide Compatibility (Right Model Selection): DALY BMS 15A and 20A protection boards are compatible with Li-ion and LFP lithium batteries. It supports configurations from 4S to 13S. However, it is critical to select the correct model based on the voltage and current specifications of the battery pack.
Temperature Monitoring (NTC Sensor): Equipped with an NTC temperature sensor, the BMS monitors the battery pack's temperature. If the temperature rises above safe levels, the BMS disconnects the pack to prevent overheating, which could cause cell degradation or even thermal runaway.
The built-in passive balance function in the DALY BMS is a practical, efficient, and affordable solution for keeping cells balanced. It works seamlessly during charging, prevents overcharging and undercharging, and contributes to the overall reliability and lifespan of the battery pack. Let me know if you'd like guidance on choosing the right DALY BMS model for your application!

How to Select the BMS for Your Battery Pack

Battery Type Compatibility: Choose LFP, Li-ion, or LTO Battery Pack.
Number of Cells in Series: For example, for a 4S battery pack (four cells in series), select a 4S BMS.
Current Rating: Ensure the BMS supports at least the discharge and charge current of your battery (e.g., 20A for 20A battery packs). Add a 20–30% safety margin if needed.
Balancing Functionality: Passive balancing dissipates excess energy as heat, while active balancing transfers energy between cells.
Communication Features: Options include CAN, UART, Bluetooth, and Wi-Fi modules. Note: Hardware BMS lacks communication functions.
