I made a 12s3p out of those $.99 hg6. Really nice. No sag great short trip pack.

Harrisonwms1 · May 27, 2020, 11:03pm

Does anyone have an extra 12s d140?
I would gladly take it

Arzamenable · May 27, 2020, 11:04pm

Pics or it didn’t happen

Makio13 · May 27, 2020, 11:05pm

Ha, I actually didnt take pics this time. Third pack so figured i was good on this one. Have to ride some time. Has great torque even with 6355’s and my small body.

Actually yes you can and it works pretty damned well if you’re stuck doing that.

We are using the wrong solder. Apparently you can solder, braze, and weld stainless to copper. A very cool article from a group of guys into DIY’ing alcohol in the basement

How To Solder Stainless Steel To Copper

If you choose to solder your components together a common plumbing solder containing 95% Tin 5% Antimony will do the job just fine. You can also use Lincon Electric Solder Stay-Bright Kit With Flux that is 95% Tin and 5% Silver for better results. Both solders will have a melting point of 230°C /450°F and can be heated with a simple propane or Mapp gas torch. You will need to thoroughly clean both pieces and apply a coating of flux to all surfaces to be soldered.

This feels all wrong

iamasalmon · May 28, 2020, 4:43am

haha, what, you afraid of a little sparkle sparkle?

A regular soldering iron gets to 450, no problem. A good one more, prolly.
That donkey-kong soldering dildo you have prolly goes to a thousand degrees, lol

Arzamenable · May 28, 2020, 5:07am

A little razzle dazzle? Ok, I see your angle.

iamasalmon · May 28, 2020, 5:15am

doing up that 12s8p as we speak

these used cells that @Dog is selling are actually testing out to have totally decent capacity, if you can live with the sag. Higher p groups required. perfect for a charge n ride.

edit:
I’m getting over 14 amp-hours on the 8p groups from 3.57v to 4.05v

Come take my spotwelder. I don’t work till next PM

Arzamenable · May 28, 2020, 5:30am

Also, I have A second ride and charge enclosure you can have

Andy87 · May 28, 2020, 5:31am

Which nickel you want to weld with it @Skyart ?
It can weld only nickel which is below 0.12mm and that’s already very thin.

Skyart · May 28, 2020, 5:37am

What do you mean? I weld .2 all the time

Andy87 · May 28, 2020, 6:53am

This one I mean.

Skyart · May 28, 2020, 7:08am

Have not ordered yet

Andy87 · May 28, 2020, 7:16am

What I meant to say is that I don’t understand why you want to buy a spot welder which can’t weld proper nickel.

glyphiks · May 28, 2020, 8:36am

For science Andy!

Andy87 · May 28, 2020, 8:58am

Ok ok… seems like I’m the only one with limited budget

glyphiks · May 28, 2020, 9:21am

Nah, you’re not alone. I don’t have money to burn on shit unless I think it holds some sort of value either.
