DALY 13S 48V 60A Smart BMS for Li-ion / NMC Battery with CAN/RS485 & UART

1. Product Overview

The DALY 13S 48V 60A Smart BMS is designed for 13-series Li-ion / ternary lithium battery packs commonly used in 48V applications.

The unit shown is rated for 60A discharge current and 60A charge current and includes communication and sensor ports for integration into smart lithium battery packs.

Its heavy-duty terminal design and communication interfaces make it suitable for EV battery packs, electric scooters, e-bikes and other 48V lithium battery applications.

3. Smart Communication & Interface Ports

The BMS shown includes multiple labelled communication and expansion ports:

• CAN/485
• UART-1
• UART-2
• NTC-A
• NTC-B
• KEY
• DIO

DALY smart BMS products support communication with compatible monitoring equipment and battery-management systems through interfaces such as CAN, RS485 and UART.

Compatibility of individual ports, protocols and accessories should be confirmed for the intended application before installation.

4. Temperature Monitoring

The unit has ports labelled:

• NTC-A
• NTC-B

These are intended for compatible temperature-sensing arrangements.

Temperature monitoring helps the BMS manage the battery pack according to configured protection parameters when used with the correct DALY sensors and setup.

5. Battery Protection

DALY smart BMS systems are designed to manage important battery operating conditions such as:

• Overcharge protection
• Over-discharge protection
• Over-current protection
• Temperature protection
• Cell voltage monitoring
• Battery pack management

Exact thresholds depend on the BMS configuration and programmed settings.

6. External KEY Switch

The product shown includes an external wired rocker switch connected for the KEY function.

This provides a convenient physical ON/OFF control for compatible BMS operation.

Included: 1 × wired rocker switch as shown in the product image.

7. Suitable Applications

Suitable for compatible 13S 48V Li-ion battery packs used in:

• Electric scooters
• Electric bicycles
• EV battery packs
• Electric three-wheelers
• Portable power systems
• DIY lithium battery packs
• Robotics and mobile equipment
• Other 48V Li-ion applications

8. Compatibility Note

Before ordering, confirm all of the following:

• Battery chemistry must be Li-ion / ternary lithium
• Battery configuration must be 13S
• Battery voltage class must be approximately 48V
• Required continuous current must be within the 60A BMS rating
• Charger must be suitable for the exact 13S Li-ion battery pack
• Communication protocol must match the equipment if CAN/RS485/UART communication is required

DALY specifically states that Li-ion, LiFePO₄ and LTO BMS models are not interchangeable.

9. Installation Note

Correct BMS wiring is critical.

• Connect B- to battery negative
• Connect P- according to the BMS wiring diagram
• Connect the balance/sense harness in the correct cell sequence
• Never reverse B- and P-
• Never connect the balance wires in the wrong order
• Use a charger designed for the corresponding lithium battery chemistry and series count

Professional installation is recommended for EV and high-current battery packs.

10. Safety Note

Do not use the BMS:

• With a different battery chemistry
• With a different number of series cells
• Above its specified current rating
• With damaged or incorrectly connected sense wires
• With reversed battery polarity

Always verify the complete battery configuration before powering the BMS.

Sources Used

The 13S, 48V, 60A, Li-ion chemistry, charge/discharge current and port labels are visible directly on your photographed DALY BMS.

DALY’s official documentation confirms that its Smart BMS range supports CAN, RS485 and UART communication and that Li-ion, LiFePO₄ and LTO BMS variants must not be mixed. DALY also documents configurable battery protections including overcharge, over-discharge, over-current and temperature protection on its Smart BMS products.
