6Pence Spot Welder - CHEAP! UK

Bought, mostly completed but never finished. When soldering some has flowed across the fet legs (where it shouldn't be!). Ended up buying a K-Weld, hence sale. Only asking £30, this is a simple fix but as others; I have enough projects on the go! http://i189.photobucket.com/albums/z313/sacko_vit/201...

Re: UK: a good custom Li-ion pack builder that can help?

What configuration are you looking for?

Do you have a specification available?

Please see one of my previous battery builds;

GearSensor vs Pasion ShiftSensor

Has anybody used the ShiftSensor? I am guessing it is a clone of the GearSensor? This seems to be half the price, and readily available in the UK. https://www.ebay.co.uk/itm/Bafang-BBS01-BBS02-BBSHD-Gear-Sensor-Cut-Out-and-or-Brake-Cut-Out-1-to-2-Cable/253567182843?hash=item3b09c827fb:m:mngqsEIoJqxd...

Re: 52v 14s4p Hailong Case

Yes. If the case does not fit, take the lid off. At the back there are two screw posts. You can remove some of the material away from the top of the posts. I also had to remove some of the material from the charger port. If the cells are squeezed together tight enough prior to spot welding, you don'...

Re: 52v 14s4p Hailong Case

That's it, 'row' 1 first. Lay the first row down. Get the glue gun ready. Start laying 'row 2' down put place glue in between first. This is the BMS I bought. Doesn't matter how long the BMS is, you have about 20cm of room at the top of the box! :) https://de.aliexpress.com/item/Free-shipping-51-8V-...

Re: 52v 14s4p Hailong Case

I used the same layout as the image on the first page. I used a wooden box which was square. I built the pack upside down. Line all the 'Top' cells up in one row (15 of them), push the terminals up tight against the side. Do not add glue at this point! Then, I start laying the next row, but add glue...

Re: 52v 14s4p Hailong Case

Mine is now complete, really happy with the outcome.

It is very tight though! Fitting the charger point, making sure it all closes once the lock is fitted is also a pain.

Re: 52v 14s4p Hailong Case

Thanks for the reply, much appreciated. Any idea why the 8 cells on the left are together? I would have thought the 2 sets of cells in parallel would be alternating (Positive group + Negative group). Something like this instead; https://drive.google.com/file/d/1EVCqOKHtbiCcIvb0Thc5fvCRqPYB-Olm/view?...

Started with plans for a 13s4p battery build, but as I am going to have to glue the cells I may as well go to 14s4p.

Re: KWeld vs Arduino Spot Welder

Many thanks for the feedback! Much appreciated.

I only have a couple of small 13s4p packs to make, and the Arduino looks to fit the bill nicely.

I was planning to purchase the 10mm2 probes that are in the shop, worth purchasing something elsewhere?

KWeld vs Arduino Spot Welder

The KWeld is over €200 delivered in comparison to the €120 Arduino kit. Are there any advantage to the KWeld? Both look good for the money, but struggling to understand the price difference. https://malectrics.eu/product/diy-arduino-battery-spot-welder-prebuilt-kit-v3/ https://www.keenlab.de/index.p...

18650 100amp discharge

Looking to build a 13s 18650 pack @ 13.5ah.

The only hitch is that it needs to have a max discharge rate of 100amps.

Coming from Lipo cells I am in new territory here, so any advice is appreciated.
