I've been powering my 2 Garmins (93sv, on a 6AH Milwaukee) and (106sv and Livescope, on a Milwaukee 9AH) for over a year and while it does work I'm about to install the 75AH Millertech for everything. My 106sv/LVS34 always dies around the 4hr mark and then I put another battery in... The cool thing is even though they are 18V you don't have to undervolt them because the Garmin head units work fine. This saved me for some $ while I saved up to buy a better battery since I already had the 3 milwaukees. I hope to get an all day, more hassle free run out of the 75AH Milltertech battery!

Hey man if it works run with it. Easier charging, lot less wieght. Most deep cycles don't last for crap anymore.

My guy says an off the shelf Miller Tech is better but we will see. Testing video is coming... Stay tuned

[@seanpottier]

Did you make a video on how long that set up lasts

[@CastCray]

I did a live. I'll be making an update video soon

[@woutlord]

Anything uploaded since then? I'm about to do the same, wondering if it is worth it.

[@CastCray]

Not yet... I will say... It works but the MillerTech batteries are a much better constant... Consistent form of power. ​@@woutlord
