I'm after a bunch of batteries and don't know where to best get old laptop batteries, hoverboards, electric scooters, etc.
Any hints?
In north west Sydney, ideally.
Thanks!
Where to get (nearly) free 18650s

Yes, most people don't know this, but the 18650s are right underneath the flux capacitor!
Do you need to be usable or just the battery?
The battery packs can be dead. If they are, usually it is just one or a couple of batteries that are actually dead and stop the rest from working.
Aldi often reduce their 4AH xfinity batteries down to $20. You'll get 10 Samsung INR18650 20Q in each one.

how do you then solder nipples to the positive?
Hoverboards? Like the one Marty Mcfly used?
