I'm having an issue with the matek 3bm1 battery monitor... when i plug in a fully charged 3s battery all 4 red lights come on along with the initial beeps. The problem is that all 4 red lights stay on until i push the buzzer button. Then all 4 lights turn off and no matter how long i hold the button in the 3bm1 will noy go into program mode.
