looks like it's time for my first post
German is my mother tongue, so I could help translating.
I think you're right, JRP3, it's not Solder-It he's using, but on that youtube link there is a new reply (in german) from someone owning a Austrian webshop for deco stuff, lighting etc ( http://www.hausschmuck.at
), who says if you want to buy this paste, you should send him a mail to firstname.lastname@example.org
to get a quote. Let me know your address and I'll ask him how much it'll cost you including shipping to US/CA. His reply was in german so I guess his english is useless, but if he owns a webshop he should have a paypal-account for quick payment IMO.
Edit: This appears to be his ebay-account, but he doesn't have anything up for sale at the moment:http://www.ebay.de/sch/hausschmuck/m.ht ... ksid=p3692
That plastic container looks like you could tin a lot of tabs with it, you could buy 1 container and then share/redistribute it within NA among forum members.
Here is another Aluminium soldering paste (out of stock, though), it says it contains Silver particles, and needs to be heated to 200 C/ 392 F to melt. The solder is said to be stronger than the Aluminium itself. They also mention it can be used specifically for soldering Li-Ion battery tabs and once the tab is tinned, normal solder can be used. You just first have to break the oxide barrier on the aluminium (which prevents normal solder from sticking to aluminium) that would only melt when heated above 2050 C/ 3722 F (Aluminium itself has a melting point of 660 C/ 1220 F), so there's special chemicals in the solder to break it:http://www.tmp-loettechnik.de/shop/prod ... issmetall/

P.S.: Thanks to everyone participating in this great forum, I learnt a lot here! A little bit of background about me: Am 35, built my first radio when i was 8, but compared to some of you guys I'll have to call myself a total noob
(Edit: just found out that noob also means "not able or willing to learn", wouldn't say that about me - know the basics, but won't ever come close to some here on knowledge about electronics)
Didn't build a single ebike to date, but love electrified kickbikes (welded from old bikes, fitness devices, metal beds, etc., Bafangs in 20", 26" & 28", A123-packs), carving around with one of these = infinite grinning
Plan to build one from Bamboo poles, awesome material, very good at vibration dampening, light and also very strong, about the same as builder's steel. You might have seen Calfee's Bamboo Bikes, beauties IMO: http://www.calfeedesign.com/products/bamboo/
