Custom Button tops. Very good to Unacceptable.NEED EXPERIENCED SOLDER BLOB EXPERT OPINIONS.

Brass is a better electrical conductor than steel or solder. Silver or copper would make the best “shim” (thick washer), but i didn’t have any available to turn and drill on the lathe.

Building up 2.5mm of solder blob is not a typical soldering task, especially with the constraint of not putting any excessive heat into the top that might damage the gasket.

So my idea was to use a 2mm shim for the bulk, and then use solder to adjust the final desired length. It made for a broader and flatter “button” than just using solder.

One thing i wonder is why would a flashlight maker design a carrier that needed such long cells? The standard 18650 cell is 65mm. An easier and safer fix might be to add solder bumps to the carrier pads, just a thought.

On adding to the carrier —- You loose the polarity protection though —- I usually only add enough solder to make it a normal button top

Thanks for the explanation. Regarding the battery carrier. They’re big enough most likely for protected batteries. That is for my Ace beam x65 Mini.

It was modded by v54. In order to shorten the length so hydrain cells can fit , he puts solder blobs on the springs on one of my carriers and the other one has solder blobs on the positive button.

The photo I provided and the carrier that’s going to be used for these batteries, are the one with the solder blobs on the positive button.

I received a sale email from 18650 Battery Store — should I email and ask if they can add solder blobs to some 25S cells —- LMAO

I got the same one so I decided to call him and we patched things up.

I’m going to have him do a hundred of the Epoch p28b molicel rewraps and 500 of the Epoch p45b molicel rewraps! Probably Grade B.

Don’t make it obvious. Pick another flat head cell to put a blob on and see what he says :sunglasses: . :person_facepalming: The name Steph,en everything’s revealed now!!

When you call up pick the prompt for Tech support. I believe it’s prompt three or two. Just listen you’ll get it! Let me know how you make out sir?!

Time for dinner than the trail with my x648 REM 3 million lumens and 697 million Candela!

raccoon · 2023-02-02T22:11:47.000Z

I got that email as well.

The cells that are supposed to be $7.75 came up $8.00 for me.

Either way, I think the MOLICEL/NPE INR-21700-P42A 45A 4200MAH are more bang for the buck, plus I don't need any batteries at the moment.

Is the dark blue cell just re-wrapped? Or different brand/batch/model?

It looks like you’re mixing cells in that carrier, which is generally not recommended… Of course free to do what you want but just wanted to clarify in case people with less experience thought it was normal.

Hope the trail and x648 was good - I can’t find info on that light, who makes it?

Please give me some credit and read the 8th sentence in the op. The answer is in there.

Do you think I would have Kennybobby repair my four 25S feeble button tops and replace one of them with some unknown and different cell? All the photos, before and after repair have that blue rewrap in there.

I would never mix cells.

I was joking with chops. I made that light up.

Sounds good, paired/grouped cells always the way to go.

Actually, in the interest of accuracy; the answer is not in the “8th sentence”.

It is in the 13th sentence. It is the 8th paragraph as written & punctuated.

Can anyone who owns KP NH1832 verify overall length is indeed 66.80mm and this is (not 65.80 or less) a typo?

I need extra 1mm length, not wanting to add spots or solder

kennybobby · 2023-02-04T18:21:56.000Z

do you need flat top or a button to make contact?

You must be bored and are certainly critical.

Whether it’s a sentence or a paragraph is irrelevant. My point is obvious.

If You’re going to participate in a thread try adding something beneficial,useful and stick to the subject matter.

Kona_G · 2023-02-05T02:00:35.000Z

@kennybobby, flat top would be optimal. I viewed Samsung INR 30Q button top cells. The specs are less length than the KP… That’s why I thought KP specs could be typo.

kennybobby · 2023-02-05T03:40:58.000Z

Probably a typo, would expect 65.0mm for a flat top.

i measured a 4 pack of button tops that are 66.5mm.

Bored??? Certainly not!! How could one be bored reading about all the nuances of solder b(. )( .)bs.

Critical??? Not in the least sir. No criticism was uttered at all.

Yes, “your point” was 100% obvious indeed… I agree. Nothing was said disputing that fact.

The only thing that was mentioned was your directions to where you point was stated in the OP were incorrect.

I pointed this out, nothing more. If we want people to read threads before they comment (which I totally agree with btw) the things we post should be accurate.

Would you not agree???

GO Chiefs!!!

No I don’t agree.

You’ve contributed NOTHING to this thread except something irrelevant. Don’t try to justify it by saying things should be accurate.

I was a psychologist for 40 years. A part of my job was to look through BS and understand all the defense mechanisms that are associated with it. Justification, rationalization, manipulation etc etc

You are an easy case.

Please go elsewhere because you have not contributed to the topic as I mentioned earlier and you’re certainly not going to fool me.

Have a good day.

Give me a break. Everything you posted on here you’re joking around about stuff.

Drop it, let’s get back on topic.

Is there a better alternative solder than 70/30 for blobbing cells?
