Battery spot welder

[CallumWK]

Not sure if this is the correct forum, but I'm looking for a business that has a battery spot welder, to make a battery pack.
I'm located in Pattaya, so the closer to home the better

Some branches of Amorn used to re-cell packs for tools, PCs etc. 

 

Worth talking to your local branch 🙂

 

Failing that there are quite a few basic ones on Lazada etc. if you only need a few welds.

Thanks I checked with them already.

Amorn Pattaya look more like a candy shop the last few years, and even many years ago they directed me to a shop in Naklua for a simialr job. That shop today said their spot welder is in heaven now.

I called Amorn SriRacha, and they said they had no such machine.

Shame, it was worth a shot 😞 

 

Are the cells you need available with pre-welded tags so you can solder safely?? If you are using 32650s or bigger they are also available with M4 screw terminals 🙂

 

Or, there are sellers on Lazada who will build packs to your specifications.

Battery spot welders are freely available on both Lazada and AliExpress. Without a power supply they are under ฿300 with an integrated battery they run from about ฿500 to ฿900.  The connection metal tape is also easy to find, along with the required Kapton tape 
 

I would not advise soldering as the heat required can easily do nasty things to the batteries or charging circuits

I want to solder 3 Lifepo4 18650 batteries in line, but I can find only these, with the flat had head. Those with the raised head are only available in LI-PO or LI-ION version. Is it possible to solder them in line?

Do you have experience with a credible seller of kapton tape, as I can see from the reviews of some listings that what they sell isn't heat-resistant at all, so fake kapton.

Other reviews are as usual, very good product - not damaged, but haven't tested yet,😄

 

What would be the use of the metal tape in my case? My application is for an electric airsoft gun, so will have to use thick wires for connection.
