Thanks for the swift reply Camracer. Any info is "useful info" to me at this point. No need to twist my arm with rehargeables....Could I use the 18650 AA rechargeables
I'm seeing now on battery websites? Would they last longer than the 900mAH 14500's?

I definately think I'd be interested in knowing more about your external battery rig. Would you (or anyone else) care to put up a pictorial on it with specifications so the rest of us can hop on the power band wagon? I think that would be really cool to see.
In the meantime I'll use the AA....and if I find out, go with a few of the 18650 AA rechargeables.
Hope to hear back from you....

Yeah KP! 18650's, like I said will last 3x or more longer than the 14500's

Re: Found: AA Battery "Dummies"

Hello Ramatam, I use nothing but rechargeable Trustfire batteries. They charge to 4.2v. Keep it in mind that batteries are charged up a bit higher than what's rated when choosing your combo of batteries. Four "3.6v" batteries will be over the stock Blackbird's limit. Three will not. You could do three Trustfires, a "1.5v" lithium and a dummy battery, as a possible combo.

Get rid if the Xeno's and go rechargeable. It does save money. My AA Trustfires are 900 mA. I rarely use them, opting for my 18650 external battery pack which has 2.8x the life. I shoot 4000 rounds with that pack (my average shooting session), and I have juice to spare!

You may soon wish to step up to a whole new world of higher voltage options (up to 24v!), and firing options at some point by installing Sergey's amazing custom circuit board! Check it out if you haven't already! ---Cam

Re: Found: AA Battery "Dummies"

So I'm a newbie to the Blackbird but am trying to learn fast.
This "dummy battery" looks like an interesting route.. Seems three high volt batteries would be cheaper in the long run than say 3x 3.6v xenos plus 3x 1.5v lithiums mixed.

My questions are:

Are you talking about using the dummies with 14500 rechargeables like the Tenergy (3.7v) or Trustfires (3.6v)?

Or are you talking about using with the Xeno 3.6v

Are 3.6v 14500 rechargeables working out for people or do they peter out too fast?

What mAh rating should be used?

Am I missing something here or would you want to go with 4x 3.6 rather than 3x 3.6? ....or are you basing it off of the peak rating of 4.2 in which case you'd be over the 15v board limit.

Sorry for all the newbie stuff....I'd just like to get something economical and still keep the voltage up.

Great site here BTW

Re: Found: AA Battery "Dummies"

Found those on accident, I didn't think anyone still made these. I built a lipo pack for mine, and don't use 14500 cells like a lot of you do, primarily because everything I have learned about lithium batteries says it's really, really, dangerous to mix them like you guys kinda have to do to get the voltage right. These are a MUCH safer solution for you. I don't want anyone's Drozd to explode on them. For stock boards, use 3 of these and 3 14500's, if you have a Sergy board, you can go up to 5 14500's, and one of these, safely.

Totalh, you should carry these, and highly reccomend against mixing anything else. It's not safe, and there is room for a markup.

These are for using 14500 lithium cells in regular AA applications. No more mixing lithiums!
