Custom Rechargeable Battery Packs

Hi Guys,

I own a portable vacuum where the battery isn't consumer replaceable and I'd like to create some custom rechargeable batteries. After some quick googling, some people salvage lithium ion cells from laptop batteries.

Does anyone have any good sources to lithium ion cells (e.g. 18650)?
Or any well reviewed hobby (or RC) chargers?
I'm assuming custom replaceable batteries may also require some connectors to charge at the hobby charger?

I'm located on the West end of the GTA.

Appreciate any help anyone can provide!

I'd be very careful if I were you with working with Lithium cells and making
your own batteries. The safety risks are significant and problems aren't rare.

It's probably a better idea to have someone rebuild them for you. NICA Power
in Mississauga is very good at that.

I have no financial or other relationship with NICA.


If you insist on charging ahead, (he heh) I'd suggest you talk with one of the Web's
most knowledgeable people about building rechargeables, Syonyk

Thanks for the suggestion and resources... i'm going to do some more research. My fear is that rebuilding the battery will cost more than buying a new vacuum (approx 100$.....sometimes on deal for 60$).
