Important Information
The Aideepen 1S-4S LiFePO4 Battery Level Indicator Module is designed for monitoring 3.2V LiFePO4 battery packs. Crucially, this module does not have reverse polarity protection. Connecting the positive and negative terminals incorrectly will permanently damage the module. Always verify polarity before applying power.
Product Overview
This module provides a percentage-based digital display for 1, 2, 3, or 4-cell 3.2V LiFePO4 batteries. Due to the voltage characteristics of LiFePO4 chemistry, the display shows battery levels in 10% increments (0%, 10%, 20%, etc.).
Technical Specifications
- Maximum Voltage Rating: 16V ±10%
- Voltage Measurement Range: 3–12.8V
- Battery Capacity: Unlimited
- Display Increments: 10%
- Average Operating Current: Approx. 7mA ±10%
- Dimensions: 18.1mm x 8mm x 6.1mm
Installation and Wiring
Follow these steps to install the module safely:
- Disconnect Power: Ensure the power source is completely disconnected before beginning any wiring or soldering.
- Identify Terminals: Locate the VCC and GND labels on the front or back of the board.
- Wiring: Connect the VCC pad to the battery positive terminal and the GND pad to the battery negative terminal.
- Verification: After soldering, inspect the connections to ensure the power supply's positive and negative terminals do not touch the pin pads on the back of the battery meter.
- Power On: Only apply power after verifying that the polarity is correct.
Safety Precautions
- No Reverse Polarity Protection: Reversing the positive and negative terminals will damage the module.
- Short Circuit Prevention: Accidental contact with pins on the back of the board during installation can cause short circuits.

Common problems
Module damaged immediately upon connection
The module lacks reverse polarity protection. Verify that VCC is connected to the positive terminal and GND to the negative terminal.
Short circuit during installation
Ensure power is disconnected before soldering. Check that power supply terminals do not touch the pin pads on the back of the board.
Before use
- Verify the battery chemistry is 3.2V LiFePO4.
- Confirm the battery configuration (1S, 2S, 3S, or 4S).
- Disconnect the battery power source before soldering.
- Identify the VCC and GND pads on the module.
- Verify polarity with a multimeter before applying power.
