can you power them with 2 AA batteries?

Generally, if you want to try safe operation of a LED, other than flashing, or color changing ones designed for 3 volts direct operation ... using a resister of about 50 ohms per volt of driving voltage produces a safe current of 20ma which falls easily within the average LED's range. Some LEDs run at 30ma, but most do not without degradation. So, trying with 147ohm resister might be a little hot, try 200ohms like the ones included with these LEDs, you should get plenty of brightness.

Yes, I believe it uses 2 AA batteries (not included). An adapter is sold separately.

You could. However, probably not enough wattage to power additional speakers.

yes they can. but a big enough battery with 12 volts of power. like a battery from a electric start 4 wheeler or lawn mower. that could give you hours of use until the battery needs to be recharged.

Yes if you wire the batteries in series so that total output is 12v. Probably looking at a couple hours if your lucky. I'd put a motorcycle battery in if I were you. Would be about the same size as 2 6v batteries.

For power from the speakers, you would want 2 or preferably 3 AA batteries. 2 AAA batteries sounds like it's for headphones only.

The batteries that it comes with are LI rechaargables , I didn't read any documentation stating they could take AA batteries. The shape of the batteries is different than a AA.

Yes, you can. However, it does not work on batteries. It is powered through the USB cable or an A/C power cord sold separately. Though, someone on here said it runs on two AA batteries. I just haven't noticed a place to put batterie because that is not how I use it.

Yes unfortunately. They last a while but you will have to find these at the store or order. Can't use AA or AAA that most of us have lying around. I take my batteries out when camera not in use.

They are 12v not sure about amps but can't be much and yes u can hook them to a battery that's 12v

You can but you will need to run them through a power amp not a straight plug and play.

Correction to my answer: I said, "two AA Batteries." Actually, they are the smaller rechargeable (two) AAA batteries. Sorry.

Unless your running dual batteries...you cant. Or u would have to unplug ur exsisting lights to allow the these lights to plug in.

The pair that I received recently from rookydeals (fulfilled by Amazon) use 2 AA batteries each.

No, it requires two AA batteries though I imagine you could use rechargeable batteries . The batteries last a pretty long time though .

I have charged 2 at a time, and 4 at a time. To date, I have not tried 2 AA's with 2 AAA's. It is a reliable charger.
