One of these packs would be good in my Ranger. It will cruise on 4 amps or if I want to go faster 50% throttle is 9ish amps  :)

I just don't trust myself to solder them and certainly wouldn't be brave enough to try making a spot welder!  I did see some once that came with tabs on, I think they were supposedly to make soldering them easier?

I also saw someone selling plastic blocks that you could use to make up packs, wish I could find the link again! I suspect they would add a lot of extra weight and bulk though which would negate the two main benefits of using the 18650's..

Lithium Ion Flight Packs....Making your own packs.
« Reply #46 on: December 13, 2017, 10:07:22 AM »

I am going to have a go at making a spot welder with the momentary switch. Really just for something to do and because I have most of the parts in various storage boxes, symptomatic of being a “sort of”retired builder/plumber/engineer/property developer. I have ordered some cells to try out. If it works, which I am sure it will, and I can work it, I’ll weld a pack up for you. Plenty of members have helped me over the years with 3D printing, repairs etc.

  Soldering was easier than I thought it would be TBH...:

 1) Use a large Iron.

 2) Abrade the surface with fine emery or similar and then wipe clean with alcohol.

 3) Apply a little flux to the surface.

 4) Apply the iron (briefly) to the flux to melt it.

 5) Tin the surface of the cell with LMP Solder, ensure you use Leaded Solder!!!!! Don't overheat.

 6) Apply pre-tinned wires to the joint and apply heat to the end of the tinned cell, (not the main wires) until it forms a joint.

 7) The wire conductors in the photo are copper, which solders more readily than steel braided, it's also more conductive.

 8) Lastly, solder on the balance wires, to the copper conductors / cell ends, do not overheat the thin balance wires.


   Flux and Solder :

                             I think the Flux came from B and Q and the Solder came from RS Supplies, note, the solder is 60 / 40 type with 40% being Lead.  Clean off the Flux residue with alcohol when you get finished, its acidic.



                                                                                               :vulture:
