Cell Level Fusing W/ Copper & Brass Battery Strips Using ComMarker B4 Laser

[@RambozoClown]

Very cool. Look forward to your testing. It's amazing what can now be done in a modest home shop.

really amazing

[@phrozenwun]

Since you are designing your own plates you should consider removing the sharp corners in your fusible sections. Sharp corners allow for high E fields which in turn is a source for arcing. Not sure if battery failure modes can lead to arcing, but if so then the resulting high frequency can cause cascade failure in other electrical components.

I don’t know James, i kind of think that you are some sort of genius most of the times. 🤔

These episodes can't come fast enough! Great work - looking forward to the conclusion of the build for the e-moto!!!

[@dcktater7847]

You didnt put notches in the middle for easy welding.

[@JamesBiggar]

Because I've never required them. They're only needed if you're using a weak hobby spot welder.

Nice can’t wait to see your test results of the fuses

[@nicod974]

About time to show all these diy battery builders who is the master...❤

Dude i want to be like you

[@enduroebikeaddict]

I was just wondering, are you sure these are copper sheets, it sure look like brass to me. Anyway, nice machine you got there, work amazingly well. Cheers

[@JamesBiggar]

Mix of both. I'm color blind so I might have them mixed up, but you can see the shade difference better in the pan shots. Brass has a similar conductivity to nickel, better corrosion resistance than copper so worth a try as batt strips. I'll learn which is which as soon as the fuses blow lol.

[@RambozoClown]

@@JamesBiggar You can tell them apart by taste.

Great work

At kzbin.info/www/bejne/j2PRgWeah71oo8k was that a bug that got hit by the laser???

[@JamesBiggar]

Lol, yep.

[@think_tank99]

Love your content brother! keep it up💪

[@andreyl2705]

awesome🔥🔥🔥

timing is crazy, just got my B4 50w laser (i beleive a non MOPA version) few days ago. Was testing it on 0.15mm nickel sheet. Had 3 hours of experementation, but results where way worse than yours. will try your settings.
