The DALY BMS (Battery Management System) module is a protection and management circuit designed for lithium-ion batteries assembled using 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 use in 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.
The BT version includes a Bluetooth connectivity module, allowing you to monitor your battery’s health via a dedicated app.
It is designed for installation in a DIY or bespoke battery pack, with the correct wiring, and provides standard protection functions: cut-off in the event of overcharge, undervoltage, overcurrent, cell imbalance, and, in some versions, thermal protection.
