    Seal acid battery equivalent lithium

    I'd be looking at taking something with me to put out the fire if salt water gets anywhere near that Lithium battery. Then again, could be safer to pack a good life jacket and then simply jump overboard. Curious where your 8Ah came from. The first bit of your link showed 22Ah battery.

    about cable gauge

    I would give it some serious thought. If you looked at the chart, the cable size for 5A @12v is 7.9 sq mm As there is no such size then one would have to decide whether 6 sq mm would suffice given the lower load you mention or bite the bullet and go for 10sq mm Either way, big bucks.

    about cable gauge

    Yes, as long as the voltage that remains is sufficient for the LEDs,......... whatever the type is...??

    about cable gauge

    2.5 sq mm is 14 gauge. 100mm of 20 gauge is hardly going to be noticed. Edit:... enclosed wire chart might make life a bit easier for you. I'd be putting the ps a lot closer.

    Powering Peltier TEC for Beer Brewing

    I see the guys over on Arduino have given you some solid advice. Assume you don't agree with their findings..??

    Drive belt schematic

    One normally simply takes a photo of the setup for later reference and fits the belts back they way they come off.

    Seven segment display odd issue

    Don't think that necessarily means a crook crystal. Placing your hand over the area is more a capacitive effect. I'd still be looking a bit further into that "apparent" liquid spill. and as Davenn says, crook connections somewhere.

    Seven segment display odd issue

    Another look at the video it seems all the displays are affected. Also, where you are passing your hand is directly over the crystal. Anything obvious there....?

    Seven segment display odd issue

    Left top to centre looks like some liquid spill on the board at some time.

    Simple current question.

    Might be an internal shunt you can change. details on meter shunts here....... https://www.neatcircuits.com/meter-mult.htm

    Car power to constant current 3.6A 50v boost converter

    You might be able to use something like this below .......... BUT at those levels I'd be inclined to start looking at HID lights. https://www.amazon.com/GEREE-Converter-8-5-48V-12-50V-Step-up/dp/B019W4C5IE

    Good rosin flux paste brands?

    Agree.....Read somewhere it is mostly for commercial operations anyhow. Paste flux (if ever needed) I use simple elcheapo chinese and seems to work fine. Ironically it is used when trying to remove components from the previous lead-free crap. Using lead-free is a bit like using blue tip silver...

    Show your circuit and application like I said above.

    Need a simple adjustable device to lower signal voltage?

    Did you post that correctly? You need to change a positive signal to negative...?? Don't know what you mean by "down by 0V........." Perhaps if you post more about what you are trying to do, I'd say many of the experienced ( as above) would be able to steer you in the right direction.

    Question about ACS758 current sensor

    May not be possible as I mentioned before given the floating nature of the shunt. Also , as I noted before, most converters are common ground output.
