Remote Battery Disconnect Switch 12V, 240A Kill Switch for Car with Voltage Display & Automatic Power Shut Off, Anti Theft Battery Cut Off Switch for Vehicle RV Boat (Blue)

My wife's truck (03 Avalanche) has a leech on the battery that only goes away if you disconnect the AC control, I have not just one, or two but 3 different AC control modules and all 3 (one is OEM, one is Dorman, and one is chinesium from Amazon) do the same thing. So anyway, after having to replace an Optima Red Top after only 1 year of use thanks to all the times it drained to 0, I bought this: https://www.amazon.com/dp/B0FF4SQDD1 now when the battery hits 11.8 volts, it shuts off the connection until you turn it back on via the key fob, and you're ready to rock. In a modern car this would probably be a bad idea but on the old truck, NBD.
