detects all/total cells voltage, NOT individual cell, much better to add a diode or 2. detects all/total cells voltage, NOT individual cell, much better to add a diode or 2.

This is a 'must have' gadget - you may wonder how much energy in the battery remains, set timer on your RC controller, but this thing gives you reall warning when battery is crytical. Recommended!

Very good alarm for single motors.



I've been testet it on DJI Phantom and Blade 350QX, but its to slow to warn about low cell, due to those 4 motors consuming alot of power.

over priced now, somehow i break my beep noise, i often dont hear them anyway, then i see the red light, scares the hell out of me,

id like to see twin beep alarms so its twice as loud, and dust protection because mine get dusty in rc car and break.

Mine came with two of the pins on the back IC soldered together. It reported fully charged 3s batteries as empty. After removing the solder between the pins the device functioned correctly.
