Hi.iv done many many Wilkie Talkies like you.its good your showing people how and what to do.i can't work out why the big plug .i use micro JST socket it's about 4-mm square I can go bigger but with a micro JST drill a 3-mm hole in the bottom of the radio then file the hole with a square file to square it off flush fit the JST socket and glue gun it in -in side the radio or Epoxy it in I use Epoxy the 10-min one.then when finished use a micro JST plug to charge the battery.i like to use small JST because it all most invisible. Your doing a great job for viewers because it helps them. What battery is it your using iv not seen them and iv seen many in years I'm in the uk .all the best
Good to have some sort of instructions. Altho it has not provided me with anything else that I do not know already with one exception being interference when near the antenna. Have to say I was looking for a clean kinda way or a quick tip and You have done it quite nasty but again that depends on likes and determination, if that works for You I'm glad and thanks for Your input.

Brilliant stuff, thanks! I'll have to try this (got a couple Motorola's that eat batteries like crazy)! Why is it that those metal contacts never want to take solder!? Have you noticed any reduction in the range... wasn't sure if the lower voltage would mean less broadcast distance!
I agree. They are power hungry! I haven't noticed any difference in the ones that run on 3x AAA. I haven't tested the range on the one that runs on 4x AAA's. I would think it might give less range as the voltage is 25% lower. But the range on that one isn't too good to start with so I don't think it would matter much. :D
vuaeco Cool thanks! I'll have to give this a try! Where do you usually buy your batteries and chargers... I see a lot on eBay but they are very often falsely rated (I see 18650 batteries labeled as 6000+ mah)
All units indicate which terminal is (+) and which are (-) so no need to take it apart or to use a volt meter. And I don't believe the 36hr loss is 42%, it's probably 4.2...
Very nice idea but wouldn't it be more efficient to use a Lipo battery with it? I actually used one for my ham radio and it was very good and additionally I just plugged one of this 0,90$ monitoring circuits to the balance terminals so that I can get a small alarm when the battery is almost discharged
Are you talking about the high discharge Lipo batteries for RC vehicles or just regular Lipo wrapped in silvery plastic? In either case, this battery I'm using is the exact same or even better. These radios don't use a lot of current so any Li-ion would do.
I'm using one of those for RC Vehicles and it has 5200mAh and even if I tune into a FM Channel and listen to some radio stations it still holds the charge for six days ( 8 hours of listening every day) and I'm just impressed and it's definitely not that heavy like six of this AA NiMh batteries I used before. Only problem is that I have to charge everything up to 7,2v or otherwise I may break the motherboard :P btw. I'm using the Floureon 7,4V 5200mAh Lipo battery and it has detacheble ferminals which is pretty handy in most cases
Great idea. But those batteries are expensive due to their high discharge properties. Why not just use 2x 18650 cells from old laptops? They are usually free and you can just pick them up on the side of the road! :D
I actually have exacly 133 of them but they're quite heavy and I gonna need to put use a lot of circuits in order to keep everything secure and I will need to 3d print a battery holder for it.. The old one had only some thin plastic inside which I broke in order to get this Lipo battery inside XD
Just tape them on the back of the unit like this: ruclips.net/video/hDK1KXWyfGg/видео.html You don't need any circuits to install the battery (like how I did in this video). You only need circuits to charge the battery. Just export a couple wires outside of the unit and you can charge the battery externally.
Nice video! I am uploading a flashlight review where I poke at the manufacturer for doing lithium throw away cells (cr123a). Can we just get a rechargeable standard going for everything already?! P.s.: tks for showing inside those Sony cells, I didn't know what they looked like.
I think Li-ion batteries require a BMS or it won't be safe without one. That will add up to the manufacturing cost. Competition is fierce and every penny save will give you an edge against competitors.
VERY GREAT VIDEO FOR WALKIE TALKIE USER, I'm afraid to try 2 lithium cells for my 4X AAA retevis T388 walkie talkie because I thought that will burn the circuit board , but you said that's just can't turned on? by the way you can easily replace A 3X AAA walkie takie with 3X 10440 with modified cable and terminal thus you can have more aesthetic walkie talkie really great video but I still can't replace my 4X AAA walkie talkies with lipo. or maybe Lipo 3.7v 10440 + One 1.2v Nimh Battery?
4 AAA is an odd ball. With 5 AAA, you can use 2S Li-ion. But with 4 AAA, you can try 1S. If that's too low, try 2S Li-ion but with a buck converter to bring it down to 6V. One 10440 and one NiMH would be a great option. But your capacity will be a bit lower.
Smartphones are crap, I was using a mobile just for the Radio, I replaced the same mobile a few times when it broke, but I had to charge it every day, so I bought a little portable Radio, and I can listen to it all night without the battery going flat, I like listening with a ear phone at night tucked into a cushion, and battery's are much better than mobile battery's so they should make a mobile with stronger battery's
Most likely you have Data, Wi-Fi, Bluetooth, GPS and display all on, thus eating up the phone battery. A radio doesn't have all those things to power on.
Lithium AAA's are NOT rechargeable. If you put them in a charger, they'll explode like a bomb. Don't confuse Lithium batteries with Li-ion. They are not the same at all. And Lithium AAA's are very expensive at about $2 each. I'd rather get a Panasonic Eneloop.
10440 cell is a Li-ion and it's 4V, not 1.5V. If you put 3 of these 10440 in the walkie talkie, it'll burn up your device because a 3S 10440 pack is 12V, not 4V. Putting just one 10440 cell in there won't work as the walkie talkie requires 3 AAA size cells in series. The only way is to put 3 of these 10440 in parallel and you have to modify your Walkie Talkie terminals as it will short out. And at $3 each, it'll be $9 total for each Walkie Talkie. The rectangular cell I used in the video cost me $2 each.
Just add some dummy cells as placeholders. I use them as well as li-ion 14500 (AA) cells in all my nerf guns. www.ebay.com/itm/AAA-Placeholder-Dummy-Battery-Batteries-Shell-for-Digital-Camera-US-Ship/152705591347?hash=item238df66833:g:55sAAOSw~jpZvNQY

What I am curious about is, what is the cutoff voltage of each radio?
Brilliant stuff, thanks! I'll have to try this (got a couple Motorola's that eat batteries like crazy)! Why is it that those metal contacts never want to take solder!? Have you noticed any reduction in the range... wasn't sure if the lower voltage would mean less broadcast distance!

I bought all my chargers on ebay. All of my 18650's are from dead laptops or power tool batteries I usually got them for free or very cheap.
Try sanding the contacts
All units indicate which terminal is (+) and which are (-) so no need to take it apart or to use a volt meter. And I don't believe the 36hr loss is 42%, it's probably 4.2...

bro can you hack a Rc remote control that uses 12 AA batteries to lithium.. thanks
Wow good luck man.

Use 16340 li-ion rechargeable cells
VERY GREAT VIDEO FOR WALKIE TALKIE USER, I'm afraid to try 2 lithium cells for my 4X AAA retevis T388 walkie talkie because I thought that will burn the circuit board , but you said that's just can't turned on?
by the way you can easily replace A 3X AAA walkie takie with 3X 10440 with modified cable and terminal thus you can have more aesthetic walkie talkie
really great video but I still can't replace my 4X AAA walkie talkies with lipo. or maybe Lipo 3.7v 10440 + One 1.2v Nimh Battery?

The antennas of these radios are bad. Change by a 1/4 wave, 16,5 cm.
Smartphones are crap, I was using a mobile just for the Radio, I replaced the same mobile a few times when it broke, but I had to charge it every day, so I bought a little portable Radio, and I can listen to it all night without the battery going flat, I like listening with a ear phone at night tucked into a cushion, and battery's are much better than mobile battery's so they should make a mobile with stronger battery's
Most likely you have Data, Wi-Fi, Bluetooth, GPS and display all on, thus eating up the phone battery. A radio doesn't have all those things to power on.
Will be best with a USB terminal.
sorry to burst your bubble but you know you can buy lithium aaa's
