Well I have been getting the battery flashing light. After some research on here , it looks like it should have 13.5V to 14.5V at idle and rev. Checked mine last night with the machine off it has 11.6. So i fire it up and running it is the same. So I am guessing it is time for a battery.

My question is has anyone tried a lithium battery in there machine? If so what brand? Or is there another brand that would be recommended?
