There are many awesome custom Makita battery adapters you can create with little effort. They help you make better use of your expensive Makita batteries. In this section, you find some example projects.
Charging and PowerBank
By adding a cheap USB PD board to your adapter plate, you can easily add a USB PD interface to your Makita battery.
While there are cheap commercial adapters that provide a simple 5V 2A USB-A connector, this project uses a sophisticated bidirectional USB PD boad:
- fast-charge any device or notebook directly from your Makita battery using USB PD 3.0
- charge your Makita battery from any USB power supply
Diagnostics
Access the yellow digital interface on your Makita batteries to check the cells, estimate battery health, or even unlock dead batteries.

Comments
Please do leave comments below. I am using utteran.ce, an open-source and ad-free light-weight commenting system.
Here is how your comments are stored
Whenever you leave a comment, a new github issue is created on your behalf.
-
All comments become trackable issues in the Github Issues section, and I (and you) can follow up on them.
-
There is no third-party provider, no disrupting ads, and everything remains transparent inside github.
Github Users Yes, Spammers No
To keep spammers out and comments attributable, all you do is log in using your (free) github account and grant utteranc.es the permission to submit issues on your behalf.
If you don’t have a github account yet, go get yourself one - it’s free and simple.
If for any reason you do not feel comfortable with letting the commenting system submit issues for you, then visit Github Issues directly, i.e. by clicking the red button Submit Issue at the bottom of each page, and submit your issue manually. You control everything.
Discussions
For chit-chat and quick questions, feel free to visit and participate in Discussions. They work much like classic forums or bulletin boards. Just keep in mind: your valued input isn’t equally well trackable there.
