[Same battery, lawn and carpentry tools]

Thanks for all the good feedback.

[Same battery, lawn and carpentry tools]

There are a lot of good multi-tool same battery options out there, but not all of them cover all tools.  For instance, I am a landlord (in my spare time) and the two most useful cordless tools I have are a drill and a weed-eater.  I bought a 18V Black and Decker single source of each back when I only had to take care of my own house, and as my side-hustle has grown I have come to consider those two of the best purchases I have ever made.  I know B&D has a less than stellar reputation, but I love them.  But, as the number of homes I take care of has grown from 1 to 17, I am seriously considering buying some new tools, but would like to keep the same basic concept of one battery for all, so I can keep of a couple charging at all times and just grab and go no matter what job I am on.

So that leads to my question.  So far, the only battery options I have found that have both a drill and a weed-eater or B&D and Makita.  Are there others I haven't found yet?
