Battery Monitor

Today I finished up the battery monitor system.    It is a tiny circuit to monitor the battery and lets you know if you have a dead cell or if (when you are flying on backup battery power) when the voltage of the circuit is less hits 11 v.  By this point the battery is just about dead.

Three of them have been made to monitor the aft, forward and emergency extention batteries.  When activated a blinking red LED light on the dash notifies the pilot.

A little heat shrink and they are nicely protected.  They are all interchangeable if necessary.
