@NightCrawl - I saw those on ebay but unfortunately they don't deliver to my country, similar situation with batteryspace, shipping via FedEx = $103 or via USPS = $42 for 2 batteries worth 10 bucks!!!
@RedForest UK - unfortunately 16650 wouldn't fit? its for a battery pack for camera that had 2 pieces of Sony UG14650GR but one of them leaked, I would just use 18650 but it's a very tight fit inside of housing.
Thanks for suggestions, if I don't find them I could probably use something like 14500
My country: Serbia (beyond the 7 seas, beyond 7 forests) :)
