As soon as I saw this thing, I immediately thought of using it to switch between 2 battery packs when the first one ran low, as inidcated by a voltage sensor on the servo line. How much current does the thing draw? I’m thinking something like a hexapod or tracked bot, with 2 of the 2800 mah packs running the servos, and a seperate 9v running the logic. For simplicity sake I would run the battleswitch off the same 9v that powered the logic, to sidestep the issue of the switch cutting its own power supply, but am wondering how a 9v would hold up to running the logic and the switch, how long it would last compared to the twin 2800 packs. Also, how would the servos handle the momentary loss of power as its switched over to the second pack?
Anyone already done this? I have a nagging suspicion I’m missing a pitfall here…
