The DALY BMS (Battery Management System) module is a protection/management circuit designed for lithium-ion batteries assembled from 18650, 21700, or 32650 cells. It ensures safety, cell balancing, and battery longevity by monitoring voltage, current, temperature, and the overall condition of the pack. This BMS is compatible with a variety of configurations: 12 V, 24 V, 36 V, 48 V, or 60 V, making it versatile for electric bikes, scooters, power banks, power tools, or other applications requiring reliable battery management.
Available in different current ratings (15A, 20A, 40A, 60A, 100A) depending on power requirements.
With SW including ON/OFF switch button
It is designed for installation in a DIY or custom battery pack, using the correct wiring, and provides standard protection functions: shutdown in the event of overload, undervoltage, overcurrent, cell imbalance, and sometimes thermal protection (depending on the version).
