Madmax input voltage?

[fixzit]

I just bought a Mag 1AA cutdown that has a MadMax plus WO TXOJ drop-in(thanks mike:twothumbs)and I want to know if I can run a 14500 rechargeable or I may have access to some 3.6v Lion 14505 disposables? I've searched the forums but still can't get the diffinative yes or no. I'm new to the forum, but I already scored in the ARC forum I got 2 of the closeout ARC AAA-P Camo's for $25 a crack
Thanks

i wouldn't recommend running them on li-ion's though since the madmax is designed to be a boost circuit and most LEDs run at a lower voltage compared to that of a li-ion. it won't be boosting voltage during the part where a li-ion still has a lot of energy left and will start to boost at a stage where the batt hasn't much energy left and is already in the critical voltage levels.

simple answer:
can you run it on a li-ion? yes
is it recommended? no

thanks for the reply and the link!:thumbsup:,maybe I'll just stick to the AA lith 1.5v's

IIRC, it also depends on the Vf of the emitter. Lower Vf's can go with a single li-ion.

:thinking: ...or was that with the BB? Don't trust my rusty'ol memory, there are a few old thread where this is mentioned.

Update, I bought a Lith Crv3 pack @ Lowes and took it apart as mentioned on some other threads, it works great:twothumbsno and no extra heat/warmth what a great little torch
