14500 li-on compatibility

Hopefully I put this where it belongs.

I tried searching but nothing definitive is coming up.
I'm going to purchase the bh109 adapter to take AA batteries in my K-50.
Can I use the 14500 Li-On batteries that are rated 3.7v with the official pentax adapter? Getting it from BH tomorrow.
Last think I want is a dead new camera.

thanks

Do you have a link for more info on that battery?
Standard Li-ion batts for the K-50 are 7.4v so it may work as long as the drain rate capacity is comparable.

Hmm are they these? They may not last long at only 750 MaH
Lithium-Ion Rechargeable AA 3.7V 750 mah Battery, LC-14500

Sanyo Eneloops are 2000 MaH at least.

not 4 of them you can't

pentax battery: 7.4V
4xAA's: 6V
4X12500:14.8v

almost guarantee that 14.8v will let the magic smoke out of your camera.

Ha Ha - thats so right on, I dont have the AA adapter so forgot you need 4! Even with spacers this seems like a 'don't waste your time' kinda thing.

Just get some of these Amazon.com : Wasabi Power Battery (2-Pack) and Charger for Pentax D-LI109 and Pentax K-r, K-30, K-50, K-500 : Digital Camera Batteries : Camera & Photo

Damn. Well in defense I thought about the 14500 because I use the bigger brother the 18650 for my ecig lol.
I do have a crap load of rechargeable batteries tho I can use with that adapter.

Should I use 1.2v or 1.5v? Aren't rechargeable 1.2? God help me

any AA rechargeable battery will be fine. most of them are between 1.2 and 1.5 v. alkaline AA's hover around 1.5 when new, but lower quickly in high current applications. rechargeable's start with a lower voltage, but hold it constant for much longer.

lithium batteries that you buy in the store are not a true lithium battery. they hold up to discharge better, but still have the voltage characteristics of a standard AA
