Actually, I never thought I’d have to–until the dreaded day came when its Ni-Cd batteries played out. Love of our tools’ performance is a beautiful thing, and as I became more and more accustomed to my B&D drill, I was less and less interested in giving it up. All in all, I was quite proud of this cordless beast and it was one of the coolest purchases I ever made for myself. However, there were indeed times when my drill was the savior and shocked the other guys, and not only that, but I am also a big guy so I didn’t mind the heavier-than-normal weight of it.

They commented often about the size and weight of the thing, as well as how ridiculously overpowered it was for the tasks we generally needed drills for. It not only slaughtered the performance of my colleagues’ older DeWalts, it even one-upped the new 18V Makita that was brought in. If you read some of my posts here on WG, then you’ll sometimes see my nostalgia leak through. I used to use a strong–quite strong, actually–Black & Decker 24v hammer drill for most of my day-to-day work in the cabinet shop and, truth be told, it was stronger and longer-lasting than anything I needed or ever had before. The capacity is increased by running cells in parallel (so instead of 5S1P they run 5S2P or even 5S3P, so EACH set of cells can give that high amperage, and the effect is additive, so a side benefit of having more cells in parallel means a higher peak output current.thus, "high output.Is Upgrading Your DeWalt Power Tool As Easy As Picking Up a Battery Adapter? Fun aside number 2: This is why the larger packs Milwaukee sells are considered high output. They'd not be able to properly function with an 18650 pack, unless you had sufficient numbers of them in parallel. This usually doesn't matter, but some of the more extreme RC vehicles can pull some serious, serious amperage. The flat batteries used in RC (and DeWalt Powerstack batteries) are capable of wildly more.hundreds of Amps. High drain 18650 batteries are capable of up to 35-40A discharge current if unprotected, and about half that (on the high end) for protected cells). I charge my unprotected cells at 4A (which, even still, is barely over 1C). So you'll usually see "Max charge rate: 1A" for a protected cell, while unprotected cells you can pretty much go hog wild on. This circuit has an amperage limitation, so the C rating is arbitrary in this case. This is because MOST protected cells are limited by their protection circuit, rather than the battery itself. Now, when you buy an 18650 battery (for flashlights, headlamps, vaping, etc), they tend to buck the C nomenclature and just talk Amps. (as an aside, this is why cell phones and some other devices say "2 hours talk time with 5 minutes of charge!" despite getting the full 20 hours of talk time takes 90+ minutes.you're not fully charging in those claims, so the CC/CV algorithm never steps down the current, thus avoiding the long, slow "top off" part of the charge cycle.) So realistically, it's probably charging at 2C most of the time, and the ramp down causes the average to fall to 1.7C average. Now, this is all theoretical to some degree.It fully charges in 35 minutes, and as packs get closer to fully charged, the current ramps down via their CC/CV curve. Then to find charging rate in amps, multiply the C rating by the capacity. With the supercharger, it says it is 35 minutes to charge.

I know Milwaukee does this (but it BURYS the data, so most people never stumble across it). So the charger specs and battery specs, you need to actually back into, based on published charge times and pack size.
