That's awesome, I was about to ask some bike shops as well!

You can use the LiPos for any other project. See how many you have of any type an figure out what they can power. I use a self made fume extractor for soldering for example. It runs on four 18650s, but it could also run on these.

You could also put them together to a pack which is rather flat and about the size of your laptop. Put a DC-DC converter of the appropriate voltage in there and you have a mobile, external power supply for your laptop.

And if I think for a little longer I can probably come up with some more idea, surely there is tons of stuff that these can be used for.

Hrmm.... I think I should get a cut of your haul ;)

Nice work. As DarkRaven said, plenty of other projects you could use those lipos with.

I like the ebike packs too.

If you get to know the brands in your area, you'll soon get to know which ones have lipo and leave them there.

It's just nice not having to clean the cells...

Try to find "local" "quality"bikes, they usually have better cells inside than the Chinese ebikes.

In Europe go for Batavus, Giant, Haibike, Gazelle, ...

One solid brand which works with the "ion" system do have pouch packs inside.

Older ones often have still NiMH cells in them.

happy hunting...

thing is they scare the hell out of me with how volatile they are... there is so many safety things with these 18650 that im much happier about..
making them flat for laptop id need a sturdy box as im very agressive with my laptop and they could get punctured, id need a dc cut off and a buck converter that can handle at least 5amps however i cant connect that to my externalpower socket due to dell use propiety data transmission to their chargers, (3 pin plugs, + and - with a data line) this is what makes the laptop "charge"
my other project is to make everything in my bedroom 12v... i got a boost converter for the laptop then found my problem... the only things in this room thats not running 12v is 1 monitor and this laptop, and in the winter a fan heater

On the Lipo, I must agree. They are much more vulnerable due to thin skin.

Also when ageing, they start to expand. Even to that extend that some of the hard plastic casings from ebike pop open...

When I flew my RC helicopter, I had the Lipo's in there, and the cheaper ones expanded after only one season. The more pricier (brand names) ones lived a longer live, but they all expand over time.

I have a kind of "volt" for putting them in. It's a heavy metal case with a vent pipe on it, so if something would happen, my house would probably be still there...
