the reviews i found at dinodirect, they said this battery, 17670, is use to replace 2 rcr123. so we found a longer life battery for the xhaler

.
now i have to wait for payday. already bought a dse905 last week.
this will be my next mod

.
question, is it worth the extra $12 to get the 510 adapter?
i have lots of 510 and 901 attys.
510 for my bartleby and 901 for my dse905
at 5v, which is better, 510 or 901???
