John, also enjoyed your article and will try your technique on a couple of batteries I am unsure of. Also, since we have an EE on the line I wanted to ask about battery setups. My partner and I have installed some new toys in our ASW20 (transponder,etc) and are wondering what is the best way add more power. We are currently running a single !2v 9amp battery. Would it be better to add another 9amp battery or to go to a single higher capacity battery. If using two batteries, what is the best way to tie them together.
