I am building a rover, that ideally I would like to power from a single 12V Marine Battery. The battery provides power to all the components:
4 hobby motors - each draws about 60 watts.
Everything works fine - until I engage the motors through automotive relays - it causes the monitor to restart. The PI seems unaffected.
My thought is that the current draw from the 4 motors engaging draws too much current and causes the monitor to have to restart.
I thought that putting a capacitor across the battery might work - as that is what I would do to prevent disruption to a high end sound system due to momentary power draw. But that did not seem to have any effect.
I can't imagine this is good for the PI either.
