Default Best decent quality 18650 + charger for SDLaser 301?

My friend is probably going to buy the SDLaser 301 from dealxtreme so what batteries + charger would work best?

I did some quick research and ended up on these:

DealExtreme: $12.30 UltraFire 3.6/3.7V Battery Charger
DealExtreme: $9.68 TrustFire Protected 18650 3.7V True 2400mAh Rechargeable Lithium Batteries (2-Pack)

DealExtreme: $9.68 TrustFire Protected 18650 3.7V True 2400mAh Rechargeable Lithium Batteries (2-Pack) <--I have some of these in my battery box and I'm happy with them.

And I have this charger and I'm happy with it: DealExtreme: $8.76 TrustFire TR-001 Multi-Purpose Lithium Battery Charger

I use cr123, 10440's and 18650's so I needed a charger that does all of them and that's it.

I read that AW batteries are good. LarryDWF has some Sanyo 18650 batteries and also offers a charger for sale. I heard good things about them.
Myself, after looking around here and on candlepower forums, I'm planing on buying tenergy batteries (protected) and Tenergy charger off Amazon.

Keep in mind DX ships from Hong Kong ( if i'm not mistaken) and will take you several weeks to get...


P.S. My 100 post

There was a thread about exploding 18650 batteries. I suggest you look it up

Cheap != safe

Yes I know.. I have seen many threads about exploding batteries and I know the hazards of li-ion batteries. And cheap doesn't meen unprotected or bad quality. Also with "cheap" i mean some decent but not the best batteries, if I wouldn't care about the quality I wouldn't be here asking for help I would just buy the cheapest batteries I could find on DX or just choose some randomly.

EDIT: I will probably just buy the battery and charger udanis suggested because after tons of research I have found only good reviews for that battery and the trustfire charger seems to be a bit better than the ultrafire and also fits the protected battery. The ultrafire WF-139 overcharges the batteries a bit, but that shouldn't matter with protected batteries because they have a protection circuit that wont let the battery go over 4.2V. Also the trustfire charger charges with a lower voltage and current meaning a bit longer charging times but longer cell life.

Wow you really did your research, always a good thing to do before posting

Ditto on the Trustfire's Udanis linked. I personally have about 15 of these and none have failed. For a cheap 18650 they are ok in my book.

neither of those chargers follow the correct CC/CV algorithm, and your overcharge/undercharge statements could both be invalid -- there are normal variances in the charging chip.. ususally +/- 5%.

as for hazards with li-ion cells.. I would lean towards trustfire for a relatively affordable solution if you have to go there.

AW or RediLast if you want to go the more expensive, but safer route.
