Description
The DALY BMS Li-ion 16S 60V 60A is a battery management and protection board designed for 16-series Li-ion battery packs. It monitors the battery pack and individual cell groups while providing multiple protection functions to help maintain safe and reliable battery operation.
With a 60A continuous discharge current and 180A ±30A peak current, this BMS is designed for higher-current 60V Li-ion battery applications.
The BMS uses high-quality MOSFETs and a protective integrated circuit to provide battery monitoring, balancing, and electrical protection.
Fixed 16S Configuration
This is a 16S fixed-configuration Li-ion BMS and is intended specifically for 16-series lithium-ion battery packs.
It should not be used with other battery configurations or with different battery chemistries such as:
- LiFePO4
- Li-Metal
- LTO
Important: This product is strictly designed for Li-ion battery packs.
60V Li-ion Battery Protection
The DALY 16S BMS is designed to protect a 60V-class Li-ion battery pack from several abnormal operating conditions.
It includes:
- Over-charge protection
- Over-discharge protection
- Over-current protection
- Short-circuit protection
- Temperature protection
- Cell balancing
- Individual cell voltage detection
The BMS monitors each battery group to help prevent over-voltage and under-voltage conditions.
Over-Charge & Over-Discharge Protection
The supplied specifications indicate an over-charge detection voltage of 4.25 ± 0.05V per cell and an over-charge release voltage of 4.15 ± 0.05V.
For over-discharge protection, the detection voltage is 2.7 ± 0.1V, with a specified release voltage of 3.0 ± 1.0V.
This helps protect the connected Li-ion cells from excessive charging or discharge according to the specified BMS protection parameters.
Temperature Protection
The BMS includes temperature protection during charging and discharging.
The specified temperature protection parameters are:
- Charging protection: Below -5°C or above 50°C
- Discharge protection: Below 70°C
- Working temperature: -20°C to 70°C
- Sleeping temperature: -40°C to 80°C
The 16S BMS is equipped with a mechanical temperature sensor to monitor temperature and provide additional battery protection.
Over-Current & Short-Circuit Protection
The DALY 16S 60V 60A BMS provides protection against excessive current and short-circuit conditions.
The supplied specifications include:
- Continuous discharge current: 60A
- Peak current: 180A ±30A
- Over-current detection delay: 1ms
- Short-circuit detection delay: 250µs
- Short-circuit protection condition: Short circuit external load
When a short-circuit condition is detected, the BMS can shut down the battery output according to its protection parameters.
Cell Balancing
The BMS includes a balancing function for the 16 series-connected Li-ion battery groups.
The supplied specifications are:
- Balance detection voltage: 4.18V
- Balance release voltage: 4.18V
- Balance current: 30 ±5mA
Cell balancing helps maintain more consistent voltage levels between the series-connected battery groups.
