2S Battery Capacity Indicator

2S 7.4V Battery Capacity Indicator
2S Li-Ion Hobby Robotics DIY Power Bank Led Panel Lithium Battery Accumulator Level Meter Test Device Portable Electronic Projects

     This compact and functional module, designed specifically for 2S lithium battery packs (7.4V), allows you to analyze the charge level of your battery according to the instantaneous voltage value. It is an ideal solution for tracking battery status in your electronic projects, portable power sources or hobby robotics work.

     The led display, which becomes active when the test button on the product is pressed, lights up gradually according to the voltage level of the battery and shows the remaining energy. The circuit, designed with energy efficiency in mind, turns off automatically 3 to 10 seconds after the measurement is made. Thanks to this feature, it does not consume energy from your battery in standby mode and does not shorten the operating time of your system.

Highlighted features

• Energy efficient: leds are active only during the test, no power consumption in standby.
• 2S compatibility: designed for use with 2S li-ion battery packs (7.4V nominal, 8.4V fully charged).
• Ultra thin design: with 5 leds, the small sized panel takes up no space in projects.
• Reverse connection protection: it is not damaged even if plus/minus are connected incorrectly.
• Clear level display: gradual view with 1 red + 4 blue led.

Installation and use

• Connect the plus/minus terminals of the indicator panel to the plus/minus terminals of the battery pack to be tested.
• Press and hold the red button; the leds will show the instantaneous battery level.
• When you release the button the leds will turn off within 3-10 seconds; there is no power consumption in standby.
