Great post invisionelite. There's very few data reported about car batteries. Fails mostly. Your feedback is much appreciated.

No. You put the negative probe of the multimeter on the main negative or the negative pin of the jst. It will be the first or the last depending on the bms model. Then you place the positive probe on each pin of the jst in order. The first time you should read around 3.4v the second pin should show ...

If you have only -b and -p then you have a "shared port" bms -p is charge and discharge wire. You must connect -b to main negative. Then you solder the balance wires in order. Double check the voltage pin by pin with a multimeter(do you know how to?) If they are ok you can plug the jst to the bms So...

To bypass the bms you must ignore -p. Both discharge wires are soldered to the pack main -&+
-b and-c must be soldered
You keep the balancing feature but you lose the lvc. You must program your controller to cut discharge. Keep that in mind or you will kill your pack.

I have been testing a way to cool the device keeping the size and price. The fets are stuck to the aluminium plate with some thermal silicone paste. Those things require to cure to transfer the heat properly so it will work better after a few hundred welds. the heat is very present there heat.jpg fo...

Cool. Share your experience with us.

Mine got hot after 30 welds in a row using 0.20 pure nickel
I didn't notice a quick heat rise using 0.15
I think you can make any pack using 0.15
I am working on a cooling mod. Let's see...
Out of the box i recommend It for 0.15mm only. I have posted a tiny modification below to use it with 0.2mm

Here you are. The A how to:

Just mail him

I've just tested copper. The results were not expected at all. 9EMc0ZXYtC4 Testing 0.05 copper on steel. It worked surprisingly well! The boss welder can't do 0.05 properly because It breaks the strip. I still need to figure out how to cool down the welder but it's definitely 0.05 copper capable HTn...

True. He is selling the MiniSpotA for 60$ USD. You still need a lipo and a charger. If you own them already it's dirt cheap. Even if you don't ....It will be cheaper than most Big ac spot welders.

I apologize. I didn't know i had to make another thread.

It seems he will sell It. Many guys showed interest.

Ok review done

Ok fellas. I have just got the A!! Let me introduce the MinispotA, probably the smallest spot welder out there: IMG_20190221_122257.jpg IMG_20190221_122330.jpg IMG_20190221_122450.jpg IMG_20190221_122509.jpg IMG_20190221_122528.jpg IMG_20190221_122700.jpg IMG_20190221_122732.jpg IMG_20190221_123053....

It is not. Lee is selling them only at Korea. If he sees some interest then will ship It worldwide. He has sent me one, will arrive this week. I'll make a review as soon as this damn flu goes away.

I will.... Stay tuned

Damn...It usually goes through. Bad lack this time.

It's sold. Thank you

Just the screen? Then the rest of the device is still ok. You can't weld blindfolded though.
Is he sending the shield to you?

That ain't that bad ... I hate when they list as pure, voters say it's pure but you find out it's plated.

I bought that a few times. I don't know if they have 0.15
