IMHO, you are looking for a solution to the result of the problem and ignoring the cause. This is being caused by an unreliable electrical system - so make it reliable. If you have a large accessory load, then this problem has already been solved too. Go back to the basics and use good heavy leads, secure connections and clean joint surfaces. I start a 10:1 comp 350 with a standard starter off an iddy biddy jap car battery through a 6ft cable and isolator switch and have zero problems since I went through each lead and connection. The battery size needs only reflect the engine-off accessory load and the level of maintenance. If the vehicle is a toy, get a battery maintainer. Steve.
