    Excelent information. One question, is the cost difference worth to do it for a regular bicycle user?

  12. Amphs ?

  13. How much will this cost?

    The best video I have seen how to do a battery. A small thing missing is a picture of where and how the BMS is soldered. May be on the numbers? I should have specified the 13 positive wires. Not the BMS itself. I am a little bit scares abouth Lithium and want to make sure I do not make any short circuit doing it. Your video is clear, well done I will be my guide doing it. My english is sometimes not very clear being french.

  15. Nice one…pls make a vid about that spot welder

  16. Thank you so much for posting the video! Quick question: Is all of the discharge-current supposed to run through the on/off switch?

  17. where can i purchase the cells?

  18. Gautam Panday talk May 12, 2021 @ 1:04 am

    I want these batteries how I order

  19. Ricardo Rodrigues May 12, 2021 @ 1:05 am

    You could with a bit of work make a way better cable management. Also the nickel strips have the middle hole so you spot weld on their opposite sides, that way the current resistance goes thru the cell and makes a better spot weld.

    Could u make and give me i will give money please

  21. Cool song.

  22. I always assumed people solder the nickel sheets to the batteries… Time to check out spot welders.

    Great video btw, definitely saving this one.

  23. Brother can I change just the cover of the battery? Please answer as soon as possible

  25. Maylani Tiarna Riasmin May 12, 2021 @ 1:20 am

    What is the material for "masking battery"?

  26. khaled alsumran May 12, 2021 @ 1:22 am

    How I can buy this MBS? PLEASE

  27. Michael Miljour May 12, 2021 @ 1:24 am

    Please give the exact kit you ordered, did it come with, bms, cell holder, nickel strips in the proper configurationEtc etc, thank you , Michael Miljour usa

  28. Just a tip, if you weld with the probes on the opposite side of the slot you get a better weld, the slot is to reduce the current flow shorting between the probes. You were welding on the same side of the slots, creating a short so most current goes through the nickel and not down through the battery.

    Among all the video I saw, I must admit it is the nicest. The only weakness, If I may say is the part concerning the BMS part that could show how i is solder and to what. Keep doing the good job.

    Do you sell that battery? If yes cost for it?
