I have been trying to track down a supplier of 18650 - Li-Ion batteries to replace in my existing external battery packs bought in 2005.
My best match so far has been from a Chinese manufacturer for $72.00 for 12 (inc battery tags - required to make-up the pack). The only problem the shipping rate is just over $78.00. Phew!
Wonder if anyone knows a closer supplier for European surface postal rates, or indeed a Far East supplier with more sensible rates.
