Battery building/welding service uk

so i have some batteries which i want to get spot welded in the uk
i was chatting to a guy on ebay who has 100 molicel icr 18650m batteries for sale
they are 2800ah and 5amps discharge i wanted to use them as a range extender for my current 12s pack

so i was looking for someone in the uk to do 1 of 2 things for me

  1. he can spot weld 2 12s4p packs and i will do the series connection and bms etc…

  2. he splits the cells with me and also does 1 pack spot welding

i will obviously pay for the service
thanks a lot

preferably uk people but eu would work

Please read post 6

@Lee_Wright might be able to help you


hopefully if he can that would be awesome

I could help if you are not in a rush (finishing uni exams in a month and don’t have the time until then).

I’m in east London. You can find examples of parallel packs that i’ve done before in my Long Range Commuter build thread.

yeah not in any rush at all

really i would like as much help as possible with battery building
i am in north west london

are you i nterested in the cells or not really?
i can happiluy wait a month especially if you can also help with the soldering side

So bit of a change here is a si read mor won batteries I think I will stick to someone else building

However since I am the U.K. and have the cells I want I think it would be most efficient to have a U.K. builder

If anyone in the U.K. can build me a pack (I will supply the cells ) I will pay up to £100 to get it built

Thanks a lot

Honestly at this price i’d throw in some money myself and buy a welder. I’m temporarily using reinforced battery clips and it’s not the most efficient use of space

I would love a welder problem is I will only ever need to weld 2 or 3 packs

How much does a decent welder cost and also I would need to find someone to split a welder with me that way I don’t waste money

I only need it for 1 pack and neither buying a welder or paying someone to do it save me any money.
I think there was a thread around here with welder reviews? Gotta look

You say 1 pack now give yourself 6 months and you will have 5 boards

Normally i barely have time for myself. I doubt that between work and home i’ll be able to come up with more projects. Really, only need one

So I at this point will even take welding done really want to make this battery and I think I can just about manage the balance cables and bms

If anyone has the please pm
@Lee_Wright I think I pmed you before


If anyone wants to get a welder to split with me then I will happily do that also

Buy cells from reputable stores :+1:

Bargains go wrong 98% of the time, run that gauntlet if you like I suppose

Thinking about it now
I just sold my 3d printer cause it wasn’t getting enough run time

So got money to spend and I think I might buy a spot welder and learn how to go slowly especially since I have time due to Covid

Thanks everyone @BillGordon I think you can close

Thanks for the heads up though

Might get some 50e from fogstar

What cell has the best wh for price?

Hello dude

I only build complete packs and I only use cells and materials I purchase. Ive got my hands totally full at the moment though, sorry about that but I have 5 batteries and 3 builds in at the moment as well as trying to quickly build my CNC table in anticipation of the machine arriving next week!
