Been a bit quiet here so I figured I would show my new addition, the gen 2 mid torque (2962). I was bit nervous to pair it with the 3.0, but after 2 days of use at work, I’m sold. I bring along a 6.0 just in case I encounter something the 3.0 can’t get but I have yet to need it. Unbelievable power to weight/size ratio. I now keep my IR in the car. Really impressed. Don’t have a 5.0 yet, but I have one coming via a rebate in a few weeks. Curious to see if there is any difference between the 3.0 HO vs the 5.0 xc
According to TTC they're basically the same. In their test the CP3.0 gives slightly more umph early on. And the test gun is a gen2 mid torque. In the real world I highly doubt you would be able to tell. 5.0 basically just gives you more runtime.
I use a 5.0 with mine since 5.0 is what I have the most of for batteries. I have 2 CP3.0s, one I use with my M18 gen3 Compact & the the other on my hammer drill.
CP3.0 is lightweight but the thing I hate about the 21700 packs is that they're longer in the front than the 18650 packs. Can get in the way sometimes. Bigger width I don't mind. One of the main reasons why I prefer to use the 5.0 with my gen 2 mid torque. I only have this gripe using the 21700s with impacts (yet sometimes I use a CP3.0 with my Compact impact
Showed up in my u-tube feed. VCG - Red vs. Flex. Will need to rewatch the video - but it looked like Flex was faster every time
