Report at 5. Besides if you already have the big D yellow tools you have a dozen or so chargers and scads of batteries. No reason to reinvent the wheel. I would put Yellow up against Red any day.
I burn yellow as that was what was available. I burned up lots of makitas to know i wanted something different. And all my yellow batteries still work. Good enough for me.
My buddies all had the older red stuff, and in very short order they needed new batteries. Times have changed, batteries have improved. I sticking with what works.
