I feel like a complete moron posting this but I feel it is very important. I know alot of us have talked batteries and helped other members with battery problems. I felt I knew enough about it until this.

I would go to start my quad. It would turn over but sometimes start hard. I would monitor the battery voltage and all seemed ok.

I know its hard to recall cause I had a tough time, but remeber when your quad was new. It seemed even in the worst case scenario you could crank on the starter and it sounded like the starter would jump out of the quad.

I just replaced my battery and WOW. The sweet sound of an agressive starter.

And the best thing, my quad starts right away again.

Just a little tip for anyone who is having a little tough time starting.
