DC 12V Battery Protection Module – Undervoltage Cut-Off & Auto Recovery
DC 12V Battery Protection Module – Undervoltage Cut-Off & Auto Recovery
DC 12V Battery Protection Module with Automatic Switch Recovery
Keep your 12V battery systems running safely and efficiently with this compact DC 12V Battery Protection Module. Designed to automatically cut off power when voltage drops too low and reconnect once the battery is recharged, this module helps extend battery life and protect your connected devices from damage caused by excessive discharge.
Key Features
- Undervoltage / Low Voltage Cut-Off: Automatically disconnects the load when battery voltage falls below the set threshold, preventing deep discharge.
- Automatic Switch Recovery: Once the battery is recharged to a safe level, the module automatically reconnects the load — no manual intervention needed.
- Charging Controller Included: Integrated charging control function for a complete battery management solution.
- SMD Package: Compact surface-mount design makes it easy to integrate into existing circuits or DIY builds.
- Low Power Dissipation: Operates at under 10mA, so it won't drain your battery while standing by.
- Supply Voltage: 12V DC
- Type: Logic IC / Battery Management Module
- Condition: Brand New
- Quantity: 1 Module
Ideal Applications
- 12V lead-acid and lithium battery systems

Frequently Asked Questions
Q: What is the undervoltage cut-off threshold for this 12V battery protection module?
A: The module is designed to monitor DC 12V battery systems and automatically cuts off the connected load when the voltage drops to the preset low-voltage threshold. This helps prevent deep discharge, which can permanently reduce battery capacity over time.
Q: Does the module recover automatically after the battery is recharged?
A: Yes — once the battery voltage rises back to a safe operating level after charging, the module's automatic switch recovery function reconnects the load without any manual reset required.
Q: What types of batteries is this module compatible with?
A: This module is compatible with standard 12V battery systems, including lead-acid and lithium-based batteries commonly used in solar storage, automotive, and DIY electronics applications.
Q: How much power does the module itself consume?
A: The module has very low self-consumption — under 10mA — so it has minimal impact on your battery while in standby or monitoring mode.
