    Great. Do you still sell 10S 4P or 5P packs for common users without spot welders ?

    I write tutorials for Cyclurba.fr : some people don't want to assemble packs and the first page of this topic doesn't mention anymore packs. So I can redirect them to you...

    I use Sanyo GA 3500 in electric scooter E-ton/Matra e-Mo+ and they are very good. Lot of tests on Internet to confirm that : among the bests, no hesitation ! :wink:

    First, my whole nickname is "Ptit Philou" :) (contraction of "Petit" that means "little" in french and "Philou" for "Philippe") And I agree that LiPos are more fragile than 18650 format batteries : 18650 seem hard to "explode" and it may happens especially when charging or with short circuits...

    Sure, disassembling batteries can be very dangerous : I do not recommand to do this. NKON is a well known store in Europe : fast and serious :-) No problems with 4 orders (tracking) and verry correct prices. According to your location, you may find other good stores but this one is reliable.

    It's almost impossible to disassemble cleanly spot-welded batteries, especially if glued. You can use Dremel tool to cut off nickel strips and a hairdryer to melt glue but you have lot of chances to damage cells or at least the tubular plastic protection. Nickel strips are very sharp and you may...
