/diy/ - Do It Yourself

It’s more than just a + and - pin, especially when you start getting into the HP stuff and newer brushless tools.

Also one of the big complaints about the Ryobi post battery design is that it comes from a time of NiCd packs and not a ton of current. On the non-HP packs, it has about half of the contact area for the + and - pins as most slide pack designs. So now you’re going to take a Chinese adapter with some potmetal contacts that are likely loose, add another set of shitty contacts with whatever slide packs you’re using, and it’s nothing but potential resistance.

And since you’re posting these new DeWalt packs, remember that you’re not going to get any real benefit from newer HP/HO packs. Most of them have a second set of + and - pins like pic related, including the Ryobi HP packs. Also there may some sort of communication that lets the HP tool recognize the HP battery. The adapters are not going to utilize any of that stuff.

Go ahead and use some DeWalt Powerstack pack, I highly doubt it will have any more power in a Ryobi HP brushless saw than a standard 1.5Ah cheap Ryobi pack. And a Ryobi HP pack in that HP saw will definitely have better performance than the DeWalt pack with the adapter.
