Im not a battery expert- but these are the batteries that I bought. This is a totally non-technical explanation: I think of them like this- they have nearly the same performance as similar rated LiIon bats- but they can be charged many more times than LiIon. The bats I got are rared for something like 2000 charges, I think LiIon are half that. Also thes LiFeO4 batteries are un-protected but they are guaranteed not to blow-up with abuse whereas the LiIon will blow up under certain conditions.

here is an awesome deal and where I ordered mine: Rechargeable Batteries & Battery Chargers - 6 RCR123A 3.0V 750mAh LiFePO4 Rechargeable Batteries with a Smart Charger -Specials

Thanks - but my understanding is that you can drain an unprotected battery to a point where it cannot be recharged. That is a big concern for me. I was also wondering if they can be recharged with a charger meant for lithium batts. :confused:
You are correct, but your vapor production will be almost nil. It is dangerous to drain a lithium battery below 2.5v. Trying to recharge a battery when it is this low is also dangerous. Risk of fire or explosion

Thanks CDDZ - I know you are certainly qualified to answer my question, since you are the SB GOD! I do appreciate it but I am still confused.

When the vapor is almost nil - is it already too late - did it drain too low?
I guess I need the Batteries 101 class. :rolleyes:

Also - can you comment on the LIFEPO4 battery question?

Thanks!

Can someone tell me about the LiFePO4 batteries. I see them on DX but not sure if I can use them in place of lithium batteries. Also - the ads say you have to use a special charger for them. Is that true or BS?

thanks!
They are lithium batteries as well, slightly different chemical makeup. The charger is usually rated for the C charge rating of that paticular battery. I am unsure if there is a pulse circuit to charge these type of lithium battery or if it just your standard trickle charger. However, if the manufacture recommends that charger then you should use it. :)

God? omg, please don't swell his head. I have to live with him! hehe

Sorry OM - but you have to admit - he is a pretty smart guy but I promise never to mention it to him again. ;)

CDDZ - you are a man that is for sure. I asked you a question.
Were you not listening to me? Pay attention!:p
