Module Configuration:

Terminal

1-Battery Cathode

2-Battery Anode

3-Output control signal. When it works correctly, outputs 5V(10k Ohm). When it runs out of battery, no voltage outputs and the resistance is 5K Ohm

4- Connect the Key Switch to the battery cathode to turn on, and open the circuit or connect it to the earth to turn off.

Features

1. All principal circuits are integrated in a single chip for long-life and reliability.2. A 10-bar LED displays the state of charge successively, bar by bar, from full to empty.3. At 70% depth of discharge(30% S.O.C), a flashing LED signals energy reserve alert.4. At 80% discharge, alternately flashing LEDs provides an "empty" status warning.5. The TCDL recognizes an improperly charged battery.6. High Voltage Reset-HVR Gauge must measure 2.35

volts per cell for 6 continuous minutes during charging.   

7. The key switch drives the LED and control pin #3. The LED does not display when the control pin #3 outputs 0V, so when pin #3=0V to shut off the electric equipment, the LED will also not display.

 8. When the battery has no load for a long time, it can intelligently track the reduction of the pack capacity caused by battery self discharge.
