Middlesex County, Ontario
18650s are the common lithium cells that are used in many things these days; laptop batteries, power tool batteries, electric car batteries, etc. They come in many different configurations; button top, flat top, protected, unprotected.

From what I understand they are easier to source in the US than in Canada. The only place I would be able to buy them locally are at weed shops, they are used in e-cigarettes.

For my Arduino projects I use leftovers from my RC hobby days. I have a great little battery charger that will charge ni-cad, ni-mh, lithium polymer, and lead acid cells:

And a ni-mh battery meant for 1/18th scale rc cars like this one:

I trust the battery charger a heck of a lot more than the Chinese stuff out there, especially Chinese 18650 chargers. Ni-mh batteries don't explode when overcharged (although anything is possible) and are much tolerant to accidentally being shorted or over discharged. The power to weight ratio is less than lithium but I think it is worth it.

The charger has been used for a lot of different purposes. I've charged aa's from solar lights, 12v marine batteries, cordless drill batteries, etc.

I also have some higher power 11.v 2200 mah lipo batteries leftover from planes that get used in arduino projects sometimes. They are a little less safe and will put out 120 amps. Same charger. They get charged and stored in fireproof bags specifically made for that purpose.
