Product Description

The Smart Battery Management System 1S 5A BMS is designed for 1S lithium-ion or lithium iron phosphate (LiFePO4) batteries. It features integrated CAN and RS485 communication interfaces for smart monitoring.

Core Functions: This BMS effectively detects and protects the battery pack from over-charge, over-discharge, and over-current short-circuits. It includes temperature detection protection and an automatic voltage balance function. Utilizing high-end electronic components (IC and MOSFET), its simple structure ensures stable performance and flexible application for various battery series configurations.

Frequently Asked Questions
How do I judge the material of my battery?
Please check the battery body. If the nominal voltage is 3.2V, it is a LiFePo4 battery. If the nominal voltage is 3.6V or 3.7V, it is a Li-ion or Li-polymer battery.
Is this protection circuit board compatible with my battery pack?
Two factors are critical: first, the BMS must match the number of cells in series in your pack. Second, the material (Li-ion vs LiFePo4) must match as they have different electrical parameters.
Why is the cell balance function necessary?
Since battery packs consist of multiple cells, performance varies slightly between them. The balance function ensures each cell reaches a consistent voltage after charging, extending the overall battery life.
Do you have a Minimum Order Requirement (MOQ)?
No, we do not have a strict MOQ. We can provide various capacities and sizes based on your specific requirements, and we welcome both ODM and OEM orders.
What are the available payment terms?
We support multiple payment methods including PayPal, T/T (Bank Transfer), L/C, and Western Union for your convenience.
What protections does the 1S 5A BMS provide?
It provides comprehensive safety features including over-charge protection, over-discharge protection, over-current protection, and short-circuit recovery.
