The battery didn’t want to charge as it has long time not been used, bur after a few attempts, I managed to put some 35Wh in there. Not super impressive, but should be enough for 1.5-2h of use.
The ST starts misbehaving when voltage drops below 11.35V
To do: design and print a clamp or other part to hold the battery in place using the VESA mounting holes (found an easteregg, try to spot in the photos!).
After my DTII-Mod I was indeed worried about the extended thermal output of the analog circuits in the ST, it’s guts get up to 42°C after 10 minutes and stay there. The battery is rated for 65°C.
Still think u got a point here. Maybe I’ll put a few venting slits in the sides as the other Analogs have.
Rather than permanently modifying the case, it would be more effective (or equally effective and less permanent) to obtain longer faceplate screws and then use a riser (even some small stainless washers would do the trick) to elevate the back half of the faceplate enough to allow heat to escape.
Sometimes people who modify cars use this trick on the engine bonnet, putting spacers under the hinge at the rear so that air blows in through the radiator cowl/inlet above the bumper and passes through the engine compartment out the back then up and over the windshield.
For you, it might not be a bad idea to put a little exhaust fan inside the box but at a minimum venting should help. I’m sure you love the syntakt but rather than later on down the road (like in a few years if there’s a syntakt 2) having to explain the permanent mod to a potential buyer seems like it could be fairly easily avoided with the same end result.
Would not look as cool as having vents in the chassis, but cool isn’t everything.
We’re talking maybe 10-12W that need to dissipate. And it does already and well through the metal case. The battery does not take much volume, but too much to go for active cooling via a fan. Peltier element would be an option but eats power and no even surface to mount it to.
So I just wing it and put an allen key with tape to the bottom.
The elevated faceplate is not an option, as there could get stuff inside when it’s in my backpack. It’s a mess in there
Will defo not take it on a plane the DTII went no problem with the internal 18650ies, but this sure looks like a suicide device on xray.
I was a little sceptical about that particular old battery from the start.
Decided not to put it in, it sat on my desk for a few weeks, I now and so often connected the Syntakt via a soldered DC plug and charged the battery at 12.6V 0.65A so very conservative. It died today.
As the ST is often accompanied by an onmnicharge, I ditch this project.
Internal set of 18650 is fine, but as for no space to put it, the ST stays unmodded.
