I am just looking for a schematic that will help me do 2 tasks
In my RC truck I am trying to run some things off of a second 11.1v lipo battery.
I am looking to find a circuit that will cutoff the load that is connected to the battery when the battery reaches 9v. But I would also like it to have a alarm or warning before it cuts power to load.
I need it to stay off until I replace the battery with a charged one, so it does not damage the lithium battery.
Can someone anyone help me with this circuit by maybe drawing me a schematic?
I have tried to use multiple schematic drawing tools so I can draw and test myself but I cannot find the components I need in the software I downloaded.
SO I am stuck.
please help!
thank you
