The Savior of Your LiPos:
The biggest flaw of Lithium Polymer (LiPo) batteries is that they cannot be discharged to zero, otherwise they swell and are chemically destroyed. If your replica is not equipped with an electronic control unit (ETU) with automatic end-of-charge cut-off, this Evolution Alarm will do the dirty work for you. It measures the voltage in real-time: as long as the LEDs are steady, you can shoot safely. When the battery is almost empty, the integrated buzzer will start beeping with a "BEEP" so loud that it can be heard clearly even in the middle of a firefight.
Compact and Universal (For 7.4V and 11.1V):
Designed to take up as little space as possible (it's slightly larger than a coin), it easily fits inside the Crane stock or in the handguard along with the battery. Its gold-plated pins are compatible with the standard balance connector (JST-XH) of any brand of LiPo battery on the market, supporting both 2-cell (7.4 Volt) and 3-cell (11.1 Volt) packs.
Main Advantages
- Damage Prevention: It warns you before the battery drops below the critical voltage, drastically extending its life.
- Powerful Alarm: The piezoelectric buzzer is very loud, impossible not to hear even with a helmet or headphones.
- Visual Feedback: The small bright LEDs indicate the reading status of the cells.
- Universal: Works with any 7.4V (2S) or 11.1V (3S) airsoft LiPo battery.

Pro Maintenance Tips
How to connect it correctly (The Black Wire Rule): Many novice players connect it backwards and burn the pins. On the white connector of your battery (the small one you use to charge it) there are various colored wires and only one black wire. That black wire is the negative. Align the black wire of the battery with the pin marked with the MINUS (-) sign or the word COM on the buzzer circuit. If you connect it correctly, it will immediately beep to confirm and the LEDs will light up.
ALWAYS disconnect it at the end of the game! This is a common fatal mistake. At the end of the day, when you put away your rifle, always disconnect the buzzer from the battery! This small accessory, to read the voltage, consumes a tiny amount of current. If you leave it attached for two weeks in the duffel bag, it will slowly absorb all the residual energy and kill the battery exactly as if you had fired endlessly!
Where to put it? Once connected to the white connector of the battery, place it in the stock of the rifle, being careful not to crush the free gold pins against metal parts of the stock tube, to avoid small short circuits. The transparent sheath that surrounds it is used to insulate it, do not remove it!
