Description
The DALY BMS 16S 48V 50A LiFePO4 Battery Management System is a battery protection and cell-balancing board designed specifically for 16S LiFePO4 battery packs. It is suitable for battery packs consisting of 16 individual 3.2V LiFePO4 cells connected in series.
With a 50A continuous discharge rating and a specified peak current of 150 ± 25A, this BMS is suitable for a range of higher-current LiFePO4 battery applications, including solar storage, electric mobility, backup power systems, and DIY battery packs.
16S LiFePO4 Battery Compatibility
This is a fixed 16S LiFePO4 BMS and is intended specifically for 16-cell LiFePO4 battery packs. It should not be used with standard Li-ion, Li-metal, LTO, or other battery chemistries unless the BMS is specifically designed for them.
For a typical 16S LiFePO4 battery pack:
- Cell voltage: 3.2V nominal
- Battery configuration: 16S
- Nominal pack voltage: 51.2V
- Maximum charging voltage according to the supplied specification: 60V
- Continuous discharge current: 50A
Battery Protection Features
The DALY 16S 50A BMS provides several protection functions designed to help protect the battery pack during charging and discharging.
Overcharge Protection:
The BMS monitors individual cell voltage and provides overcharge protection when the cell voltage reaches the specified threshold.
Over-discharge Protection:
The BMS helps prevent excessive battery discharge by disconnecting the battery when a cell reaches the specified low-voltage protection threshold.
Over-current Protection:
The BMS monitors current and provides protection against excessive discharge current.
Short-circuit Protection:
The short-circuit protection function can disconnect the battery output when a short-circuit condition is detected.
Temperature Protection:
The BMS includes temperature-based protection for specified charging and discharging temperature conditions.
Cell Balancing
This BMS includes a passive cell-balancing function with a 30 ± 5mA balance current. Cell balancing helps reduce voltage differences between individual cells and can improve the consistency and usable performance of a 16S LiFePO4 battery pack.
The balance function starts around the specified 3.5V cell-voltage threshold.
Balance Wire and Temperature Sensor
The BMS comes with a 17-wire balance/sense cable and connector, allowing the BMS to monitor the individual cells in a 16S battery configuration.
A temperature sensor is also provided for temperature monitoring and protection.
Suitable Applications
The DALY 16S 48V 50A LiFePO4 BMS is suitable for applications such as:
- 48V-class LiFePO4 battery packs
- Solar energy storage systems
- Home energy storage
- RV and camping power systems
- Electric bicycles
- Electric skateboards
- Electric mobility projects
- Power tools
- Backup power systems
- DIY LiFePO4 battery packs
- Portable power systems
Important Compatibility Note
This BMS is designed specifically for 16S LiFePO4 batteries. Before installation, make sure the battery pack contains 16 LiFePO4 cells connected in series and that the charging voltage, current, cell chemistry, and BMS ratings are appropriate for your battery pack.
Do not use this fixed 16S LiFePO4 BMS with other battery chemistries such as conventional Li-ion or LTO batteries.
