Partially completed adapter which turns my Stihl batteries into a 13.8V power supply. For ham radio, or maybe nowadays an emergency/disaster. @W6KME has one he built and I thought it was a great idea. #electronics #project

In response to this post@ai6yr 1/2 Nice! I realized one day that I didn't need fancy new ham-specific LiFePo batteries; I have a garage full of power tool batteries. DC/DC converter to step down to 13.8 volts and Bob's yer uncle.
The 8AH 20v battery here is about 13AH at 12v, and will run my 100w HF rig for an entire day of portable ops with no issues.
@W6KME Oooh, mounting the heat sink on bottom, that might be a better idea. The longest part of this project (which took WAY TOO LONG) was getting the stupid Torx screws out of the hard plastic. Two I got, but the other two I spent 30 minutes drilling out, and then ended up wrenching them part by force LOL. Curse Mr. Torx.

@ai6yr 2/2 Remember Power Wheels? When they quit selling replacement batteries, owners were stuck until people started making power tool battery adapters. You'll find them for any brand on eBay. wire that to the DC/DC converter, add power poles or whatever, and off you go. Battery running low? Snap on another, just like your drill.
