There are some flashlights which can use 1AA cell and a rechargeable cell can also work well.So,I really want to know if there is a falshlight which can use 2AA cells and also apply to rechargeable cells?I want to buy one.
Of course, I have this and it is a good one
I made a review here Review: Jet-Beam BA20
Ths!
What type of rechargeable? Nimh or Lion?
Almost any light that runs on 2 x AA alkalines will also run on Eneloop rechargeables.
Or are you talking about 3.7v Li-ion rechargeable batteries?
Right,This is what I just want to know.
Another good alternative: ITP SA2 
RC-N3 can use 2-AA or Ni-MH with extension or 1-16340 or 1- CR 123 without. I get complaints about the strobe being too bright for my bike every time I use it.

1 AA, 2AA or 0ne 14500 rechargable .... there are people on the site who have run 3AA's as well with 2 extra 2.50$ body tubes
3 AA's is probably pushing it a bit ..i tried it just for fun with some not so stellar alkalines
the body tube is one of the nicest 2$ add ons you'll ever see and the indent for the cigar grip just makes it much nicer .

Dx sells the xpg version as well as the version they all call a q2 or a q4 EZ900 xre.. Tints are good and the light is very bright
-- Balder se-1 xml AA the extention tubes are nack in stock at edc plus
Thank you. 
Every Fenix with AA batteries will work perfect on nimh’s.
