IMAX B6AC V2 Charger Broken Trace

I wouldn't bother with paste solder.

paste flux do you mean? 

I didn't know there were different kinds. I'll get that 40g tin then. 

Got a liter of 99.9% iso alch already, great for cleaning gears and gearbox when doing a clean start build.

Thanks for the cheaper sponges, but I need something that' gonna hold them, like https://www.amazon.co.uk/Soldering-Cleaner-Wire-Type-Holder-Cleaning/dp/B07MHSTGRW/

Yup I meant flux... Getting carried away there. I do tend to edit a few times after posting as I'm good at making small mistakes like that!

That flux is a hard brittle tree sap. It's melted into the tin and you can usually just crack it into fragments at the edges for making the liquid leaving the bulk of it solid. If you want a solid block and a broken block buy 2 they normally have multibuys on the same product.

It's not just the tools, it's the whole system.

I picked up a load of ex MOD gear a few years ago dirt cheap, Among it was a lovely roll of the really thick masking grade 3m kapton tape, and a few full rolls of Omega 63/37 with fast flow flux 2% flux. It blew my mind just how much better these products were than the standard store bought products.

That solder is £40-60 for 500g's compared to £20 for some cheap lead free stuff from amazon. But holy shit it's a night and day difference.

Equally flux. You can't solder without it. Well you can but it looks like shit - See above. A couple of cheap rosin blocks is a couple of £. A few dropper bottles (ask anyone you know who vapes), and some Isopropanol alcohol. Fill the bottles about 50% with IPA then break up one of the rosin pucks  and put different amounts in the bottles... Will give you some really good flux for very cheap, and different grades for different work... Thin and low content for clean work, High content thicker for dirty work and wires. Ebay Colophony flux and you should see the little tins, It's a brittle tree sap. You can also just dip the tip in it. Smells divine.

100% this. If you're using good flux cored solder though you shouldn't need additional flux. Also - you can get the Omega stuff for about £30 a roll if you shop around but yes, it's proper gear.

Also - when I mentioned the whole apprenticeship thing, we spent weeks and weeks just doing soldering exercises! We were expected to work to aircraft grade standards at the time so we also learned about the joys of looming and lacing but that's a whole different story!

So much headache...I will give you my simple fix in the evening, let me arrive home and upload a video.

I spent some time as a wireman in controls engineering in my early days.

Numbering cables and point to point wire wrapping and,as you say,looms and lacing. Lovely work when its finished. Very rewarding.

Dang man. I just got around to watching this and I guess you missed the rest of the thread where I've determined that the balance connector board is perfectly fine  (It even has balance error when you try to charge a lipo with no balance I was sitting there like "oh nice an easy fix - it's turned on and not apart!" hehe.

Edit: Okay holy shit. I tried it anyway, and it works. I don't know how, I mean there's a video of me right there checking all the traces and it's fine. But it works. Thanks for that, one less thing I need to re-buy now.

I suppose my idea about trying those 'balance connector boards' would have actually indeed worked, since they plug into the large connector.
