I looked at HKJ's comparator and it looks like the sanyo 2600 red is one of the best batteries out there in terms if keeping a higher voltage for longer then the rest except for imr's ,panasonic 2250 and lg pink 3000 mah and 2800 at 4.30 votls . I have the xtar 18700 2600 mah which I think uses the sanyo 2600 mah and looking at the charts the sanyo 18650 out performs the xtar voltage wise .
Yep! That's right. This ebay seller "doingoutdoor" is selling the red sanyo 2600's for $12.50 a
pair plus two bucks shipping. If you could get them to accept a "Best offer" of say, $ 11.00 a pair you could get a
pair of sanyo 2600's for only $13.00 shipped! Intl-outdoors couldn't compete against a price that low! Even the list price is a steal though. I wonder if folks realize that price is for a
pair of cells. Better hurry though, the listing says "4 available / 10 sold".
***UPDATE*** Just had an offer accepted for four sanyo 2600's at $11.00 a pair. With $2.00 shipping that works out to six bucks a cell. I'm liking this seller!
