Well the set of little volt meters arrived from Amazon and one is in place being tested. 100_1707-1 by John Moore posted Apr 29, 2022 at 5:32 PM Currently reading 4.44 volts.
Well after getting input and realizing my shortcomings I decided on a mechanical means to limit my voltage output on the power pack/ throttle. So after the voltage meter was installed and the throttle set to a max of 4.5 volts I designed a simple no frills throttle stop out of styrene tube and rod. 100_1708-1 by John Moore posted Apr 30, 2022 at 1:54 PM Here is the throttle stop in place. A simple slide down with a lock notch to keep it from moving. Now anytime the 4.5 volt max critters are running the lock notched stop keeps the throttle from being advanced. 100_1709-2 by John Moore posted Apr 30, 2022 at 1:54 PM
