• Over voltage range: 4.25-4.35v ± 0.05v; Over discharge voltage range: 2.3-3.0v ± 0.05v
• Maximum operating current: 0-25A ;Maximum transient current: 34-40A
• Wiring:(please check the picutre 3 wiring diagram)Strictly according to the diagram wiring: 0V(B )3.7V(B1)7.4V(B2)11.1V(B+), Do not deliberately short circuit. After the line is connected, Need to charge first, then have output.
• When the battery is connected in series with 3 groups, Please ensure that the voltage of each battery is the same. If not same, please fill in each set of batteries and then use. Do not mix the good battery and the battery.
• Attention: Do not mix the good battery and poor battery to use. The internal resistance of 3 battery capacity are closer will be better.

• 4 in 1 Charging + Discharging + Lithium Battery Protection + Battery Level Indicator Module. Lithium battery protection function: over-current, overvoltage, over-temperature, short circuit protection.
• MCU users, if you accept a small load KEY can be connected to the microcontroller about 20s to provide a low level allows the module to continue working. Trigger mode: low level trigger (ground)
• In discharge mode (The charging mode KEY function is invalid), trigger the KEY port once to open the output; continuously trigger the KEY port twice to close the output.
• The first time the load is connected, the output is automatically turned on. If the load is less than 50MA, the output will be automatically turned off after 30 seconds; if the load is greater than 50MA, the output will be automatically turned on.
• Allow discharge while charging. (Note: At this time output voltage 4.7 / 5V)
