This is kind of a tip and kind of a question.

I recently needed a little more power out of my puny Hobbico 90 starter. So, I thought, gee I could hook two gel cells up in series and run my starter at 24 volts. It accomplished what I needed but with some obvious drawbacks: 1) my starter won't last as long if I do this on a regular basis and 2) if my engine is hydrolocked, I have a greater chance ruining it.

My intent is to only use 24 volts when it's cold or with a new tight engine. I made up a special adaptor so that I can use it only when needed.

Anybody else have more experience useing 24 volts?
