If I may join in here. I also use the Odyseey battery and found it to be very good. The cold cranking amps do the job for me. I have it mounted behind the seat. I used a aluminum battery box and attached it to the cross member behind the seat using adel clamps. I used #6 copper then went to the #4 welding lead. Good move and it starts much better.

I have been interested in your discussion as I brought this up on the Matronics list. I got the hell kicked out of me for using such a huge battery. Try starting your plane when its 0 and you find out why. I guess we all don't live in Florida ha.
