Details
Monitor a 3–16S lithium battery pack in real time with smart protection, waterproof housing, and 100mA passive balancing.
A compact 75×48×14mm footprint helps save space in custom battery packs; cable length is typically 300–450mm (24AWG).
Key electrical and protection parameters are summarized for quick selection between the 40A and 60A versions.
Suitable for common lithium pack formats—prismatic, cylindrical, or pouch—in applications like e-bikes, portable power, and AGVs.
Multiple communication options (CAN, RS485, UART) support integrations such as Bluetooth, WiFi/4G modules, and PC tools—accessories may be purchased separately.
The SMART BMS app for iOS and Android displays SOC, voltage, current, temperature, alarms, and cycle data at a glance.
Use the PC software to read data and adjust key parameters when connected via UART/RS485/CAN.
Daly Cloud enables remote fleet management and data logging when the BMS is connected through Bluetooth, WiFi, or 4G.
Built-in temperature protection and 100mA passive balancing help improve safety and keep cell voltages more consistent.
Advanced thermal design is intended to reduce temperature rise during charge and discharge.
Low standby draw helps reduce battery drain, with sleep current under 500µA and working current under 15mA.
Practical build details include snap-on connectors, a clear status indicator light, and a compact housing for easier installation.
