16S-40A LiFePO₄ (LFP) BMS — DALY Model

Overview
The DALY 16S-40A BMS is designed to manage and protect 16-cell LiFePO₄ battery packs connected in series. With a nominal voltage of 51.2V, it supports a continuous discharge current of up to 40A and provides essential protections, cell balancing, and optional smart monitoring.

Features

• Automatic passive cell balancing during charging

• Individual cell voltage monitoring and cutoff control

• Protection for charging, discharging, and temperature limits

• Optional Bluetooth app support (DALY Smart BMS)

• Suitable for mid-power LiFePO₄ battery applications

Applications

• 48V to 51.2V LiFePO₄ battery packs

• E-bikes, e-scooters, light electric vehicles

• Solar and off-grid energy storage

• Backup and portable power systems

• DIY battery builds requiring 16S configuration

Important Notes

• For use with LiFePO₄ (3.2V/cell) batteries only

• Proper connection of all balance leads is required

• Ensure the charger and load do not exceed the 40A continuous rating

• Smart functions like Bluetooth require compatible BMS versions

• Cooling or airflow may be needed in continuous high-current environments
