Perilously brief hazard run time

I am not too sharp on electronics, but I can follow most of your calculations..are you calculating the momentary spikes of power usage .. like on the flashers, is it 50/50 .. 50% battery draw, then 50% rest ? maybe you have that figured in there somewhere and I just didn't see it.. do you have any pics of your bike? does it have bags and rear box? how about a reserve battery balanced by installing it in the top box.. it will raise the center of gravity a little , but may be another solution.. when I had my boat, I always had a dedicated battery for starting the engine.. it was always a bear to try and push start it !! .. haha ..
