So i'm working on making a type of spy walkie talkies, where the button is in your hand and you have the headphone in your ear, and then you also have the mic attached to your jacket, or whatever. But the original walkie talkie is a very hand held small one, that has very good distance and takes 3 triple a batteries. The problem is that those batteries die so very quickly. They go out after an hour of use, so i was wondering if i could step it up to 3 double a batteries. I dident know if they output different wattage, and i don't want to break this very cool walkie talkie. So i was wondering if i could use those double a's instead of triple a's without killing the talkie

thanks for any help!

can't say i had the same experience...

the ordering was fast, and shipped the same day, but they have there company in the very south of America. I live in New Jersey. Shipping took about 5-8 days if i remember correctly. But i can't blame them, they're on the other side of the country....

idk if it's shown on the hummbot link, but are you using a 9v battery to power ALL that stuff?

or is it a larger voltage batteries?

or do you use opto couplers, and separate batteries for the motors?
