Lipo low voltage alarm buzzer suitable from 2s - 6s with a changeable alarm setoff from 2.5v to 3.6v
But I wish you could change the sound to 'cooee'
All of the components are well mounted to the PCB, and the clear heat shrink helps protect and strengthen everything. Works perfectly.
This Lipo buzzer alarm does exactly what it is supposed to do. No issues whatsoever and at a good price too.
