2 x 3000mah protected ultrafire 18650's including shipping for approx US$6.77..
(Depending on exchange rate).
Seems like a damn good deal for high capacity, protected 18650's.
These seem to get a reasonable review in the 18650 battery reviews on cpf too.
That's not bad. You could even save a couple of cents if you ordered directly from them and used the coupon code "10%Ebay110" (10% off, with an additional 5% for new customers).
