Re: Spot Welding Copper Strips to 18650 Battery Cells

i couldn't get diy plated copper to work, the nickel would just vaporise off and get bad welds. Correct. We even electroplated the copper with nickel ourselves. Tried several times. Never could get consistent welds yeah, and it pisses me off because iv opened powertool packs to find they have spotw...

Re: Spot Welding Copper Strips to 18650 Battery Cells

So my conclusion is if I go with these particular cells, a 2mm thick "holey"copper plate may be better, and the "laminated" .15mm nickel may be the most practical way to get from the copper plate to the cell. I may try a nickel-copper sandwich using the .15mm nickel and the 2.0mm copper plate once ...

Re: Spot Welding Copper Strips to 18650 Battery Cells

I can only speculate as to why the copper/nickel sandwich works, but...for some reason it works. from my observations i think the nickel sandwich works cause the nickel heats up enough to fuse the copper to the cell. with straight copper to cell, it would only work with tungsten electrode tips. the...

Re: Spot Welding Copper Strips to 18650 Battery Cells

copper to nickel or cell=tungsten tips
nickel over copper to cell or nickel to cell=go with fat copper rods

Re: Recognize Nickel Purity...

put 2 pcs in a jar of vinegar and add a tbl spoon of salt. hook them up to laptop power supply or battery, if the solution goes clear green colour, its nickel acetate (pure ni) if it goes brown or muddy,its got steel in it. take care the alligator clips dont go in the solution.

Re: mega copper battery spotwelder

Seems your big battery has alot of reserve being as large as it is. It also adds alot of resistance. You would be better off with a single 3s lipo with a 75-100c discharge for more punch. This single battery would have very low internal resistance and would cost around 75 to 100 dollars thou. thank...

Re: Hubmonster teardown

Take a close look on the connector shown on the last picture. Are there numbers from 1 to 10? Pins 1 to 5 are for the first set of halls. On mine there was a "nose", a hook that secures the connector. First set of halls is on the side of that hook. Should be the cables on the right side of the last...

Re: Hubmonster teardown

here are some pics. not sure what bike it came off, probably a zap.
does that look like the stock connector you spoke of?
iv stripped the stock paint back and was planning to coat it black, but as i said ,i havn't opened the covers as yet.

Re: Hubmonster teardown

i have a hubmonster i never opened, i didnt come with a controller. is there some method for figuring out which halls and phases match up? i like the sound of the nucular controllers, i have some adapttos i could use but i suspect the nucular ones are better for tuning.

Re: Hyperion EOS 1420i NET3 14s Balance Charger...

just an update: i discovered by accident that i can charge the necropacks in "store mode" until they reach 3.6v or so, then using normal charging for the rest...now i have to find out how to enter store mode, as i found it by accident when pressing the buttons.. :)
