XP-3 Jump start battery

One item I carry in my on board tool items is the XP-3 Micro-Start Battery. Hard to find, may need a different model, but I also have the pigtail linked below connected to my starter battery should I ever need to use the jump battery.

I have a similar setup, but with a Noco Boost Plus (GB40). (Also with a harness.) When it arrived, I immediately saw there was going to be a problem. The buttons for turning it on and for turning on its flashlight are right on top, easy to accidentally press. I put it in my flight bag when I headed to the airport, and sure enough when I got there and pulled it out the light was on!

I designed a small cover for the two buttons in Solidworks, and 3D printed it at the library. Stuck on with some thin double-side tape, it looks a little Jethro, but does the job. A similar device really saved my butt last year in my sailboat, so I'm a fan of these jump start batteries.

For future reference (mostly mine), due to the low internal resistance of Lithium-based batteries (e.g. EarthX ETX-900), it is not possible to "jump" them in the same way that you can with a Lead-based battery without "bad things" happening. So please be careful with "jump packs" and the EarthX batteries used in recent Carbon Cubs. You can find more details in other threads on this forum.

I'd love to get @earthxbatteries opinion on this as they sell a jump pack.

I'd love to hear about someone actually testing out a XP-3 or NOCO or EarthX jump pack.
