Some of the specification in post 1 are for the AAA E01R not the AA E10R
"High efficiency circuit board provides up to 35 hours runtime on lowest output level" this is for the AAA E01R it`s 100 Hours for the AA E10R on lowest, other facts might be cut and pasted as well.
It looks like the E10R has the same problem charging nimh battery`s according to the review in the link below got 1.39v 50% however he got 4.19v on li-ion which is a full charge.
Does Jetbeam know about this problem, do they have an REP on BLF?
I will check the resting voltage on an Eneloop charged in the E10R once I have it in. I will be pretty disappointed if it indeed only charges to 50% capacity, the whole point of buying the E10R was because of its inbuilt NiMh charge capability.
Well I got 1.38v hot out of the flashlight on my AAA E01R and the guy who reviewed the AA E10R after i asked said he got 1.37v maybe this has been fixed in the latest batches but i don't want to get stuck with a couple of E10R when i am already stuck with an E01R though i am still using it.
This will not be a problem for people who only want to use li-ion cells as it charges them fine to 4.19v according to the review.
