Nice work. I did the same thing to a front-lit Gameboy Color about 2 years ago.

Kam Mil exactly haha

[@hankhill8951]

Kam Mil so I can solder them to the big pads instead of them tiny ones?

[@Reman1975]

I'm not exactly a fan of packing the charging board in with the battery. Those TP4056 chips can get pretty warm when charging a battery from flat, and while it's unlikely to cause the Li-PO to catch light, having one spot constantly getting toasted is likely to reduce the batteries overall lifespan. On the original pocket there's just enough room to fit a TP4056 on the other side of the board between the D pad and B button. You need to chop off the middle motherboard mounting post, but it still works fine without that, and this also gives you that screw hole to feed the 6 wires neatly through to keep them away from the button contacts (A small amount of heat shrink tube around all the wires at that location is a good idea). To mount the charger to the motherboard you can just use a couple layers of car body double sided trim tape to lift it up away from where the button rubbers fit. Putting the charging board there is also pretty cool if you have a transparent case because you can see the charge indicators through the front of the case. I'm pretty sure this same approach would work on a GBC.

[@golden-sun]

i just came from your limited edition gameboy color restoration vid and im super surprised you only have 10k subs.

[@g.f.2775]

Hes gonna blow up soon

[@Yrouel86]

This is a nice mod but there are a couple of things to keep in mind. The chip on the battery module (TP4056) does get pretty hot when charging at the full current (default 1A) so it'll cook the battery on top of it; I understand there isn't much space left inside the GBC but that chip and the battery should be as far away from each other as possible. Another thing is that you can keep the original jack, basically you can wire its input to the IN+/- of the TP4056 board and the output of that board to the battery terminals. This works because when a device can use both non rechargeable batteries and an external power supply when you connect the latter there won't be any voltage pushed to the battery terminals so you can piggyback on to this mechanism to include the battery module. In other words when connected to the external power supply the current would flow both to the GBC and the battery module charging the battery but won't backfeed to the battery terminals while when disconnected the battery will supply current instead this time to the battery terminals. EDIT: Also those battery modules can be safely trimmed quite a bit both on the input and output sides especially after removing the usb connector so you can perhaps have more flexibility on where to position the now smaller module. There is another version of those TP4056 modules without battery protection which are even smaller but the battery must have protection itself in this case.

[@RomeoGoesRetro]

Hi, Thanks for the video!! I had to use a Diode on the positive output to the GB. (I am not an expert in these matters) Without the Diode the voltage was too high for my backlit screen. Apparently the Diode serves 2 purposes, ensuring voltage doesn't flow in the other direction but also decreases the voltage by about 0.7v. Taking into the 3.3v range the components expect from 2 AAs. Works perfectly now. Cheers.

[@Pale-Snake]

this is a late comment but did you used the 1n4001 diode?

I did something similar on my gbp a few years ago used the same battery from my möbius action cams. 870mah gets me 8+ hours with the backlight on. Although it was a one way mod, I love it.

[@m2kkillshot]

Just thought I would point out the fact that you did not need to remove the micro usb port on the charge control board as it has two small pads on the outer side of the port for you to solder your own port to. Less of a chance to damage the BMS board that way.

[@daijoubu4529]

Also will provide more mechanical protection to the soldered wires, those tiny traces are quite fragile

[@ericochoa4034]

They also have aa rechargeable lithium 1.5v batteries on Amazon! So instead of hacking your gameboy you can just use lithium batteries. They keep a constant 1.5v volts of power throughout their rated capacity. I've been using them as opposed to nimh batteries with great success. I've found some with up to 2000mah capacity of course I dont know if that is completely accurate either way they have lasted me forever and I have a mcwill and everdrive cart and never have an issue with it firing up the first try!

[@Klikkitse]

Should work - except you have no way of knowing the charge state. The small indicator LED on the GameBoy works on voltage. Since the lithium cells keep their voltage until the very end you'll have zero notice when they go out.

FYI NiMH batteries use mAh rating too and are available in 1200mAh up to 3000mAh per battery. Theoretically since they are in series the capacity remains 1200-3000mAh

[@hermocrates]

I know you just had the charging board loose in there, which is fine, but if you found a clean way to keep it in a fixed position, being able to see the charging light through the back of the case would have been a nice touch. A simple small drill hole through, and maybe even some more of the insulating tape to hold it fixed. If the LED changes color or turns off when the battery is charged, then visibility of the light would be very useful.

[@spokehedz]

They sell that same board, but with USBC which is what I would use since that is what phones are changing to these days now. But cool, and good job on the video! And also, relocate the LED near-by the case so they could weakly shine through... Otherwise, remove 'em so that you can save some battery life since it won't use any current to light up a light you can't even see anyway.

[@DTeK]

Nice mod, i still have my GBC, i loved your video but maybe it was better to use a step down converter to drop that voltage to 3 Volts, a tp4056 will fit there perfectly

[@bubble_ghostie3438]

Great video! It came out really well. Does the battery move around inside the shell much or does it fit tight enough to hold it in place?

[@esotericsean]

bubble_ghostie Thank you! The battery barely fits so nothing moves around at all. If you use a smaller battery (any 3.7v LiPo should work) you don’t need to remove the entire battery compartment so you may need to secure the battery.

It sounds strange to me that you would be getting so much more playtime from a lipo battery. You are using a 2000mah battery, but if you get good NiMH rechargeable AA batteries they also get close to 2000mah and are already rechargeable. Maybe you were just using some very old batteries? The lipo battery will also start to drain faster when it is used often.

[@daijoubu4529]

2AA will provide 2.4V*2000mAh=4.8Ah whereas a Lithium ion, being 3.7V, will provide 7.4Ah, a 54% increase, the Lipo will also have a longer usable voltage range

[@NiliusJulius]

@@daijoubu4529 The 2.4 and 3.7 volt does not make a difference in this case, since he is connecting them directly to the battery terminals, the lipo battery just pumps in more voltage than the AA's would. The current draw will also be the same, so they should last about the same time. So I agree that the watt hours of the batteries are different, however the way they are used, they should last them same amount of time.

[@anthony_kane]

Yeah the onboard DC/DC converter boosts the 3.2 to 3.3 (Everything else)/5v (CPU)/+13.6v & -15v (LCD) with a minimum input voltage of 2V, the sad thing Is I don't know of the maximum voltage and I believe the regulator was custom so no easy to look up part number. I do know that 3.7v is fine but have been told anything more than that and it simply won't power on so I'm not sure if OP has tried with a fully charged battery yet.

Hi Sean, just found your channel! I've only recently gotten into GBC modding, and your videos are a godsend. I've been debating between this and the method in your other rechargeable battery video - while I know this is more work, it seems like the extra battery life is worth it!

i really appreciate these videos man! Thank you so much! I've recently gotten into the world of Game Boys because of the r/gameboy subreddit lol and have been modding my systems over the last few months and this video is just literally perfect timing to go hand in hand with all that lol! i'm currently almost done modding my AGB GBA with a 101 screen and all that jazz, with a new shell and everything! the one things i've desperately wanted is to give it a rechargeable battery like this as well, the only thing is that there's no easy and simple solutions that i can just do with more available and ready to purchase locally, parts! like i'd LOVE to just be able to solder whatever power set up the GBA sp had, onto the AGB and call it a day, and i know it's not that simple so yeah lol! One thing i've really wanted to ask you, was could you do a tutorial for a power solution like this video, but with a typicall pass-through solution? like basically just be able to charge the system while playing on it, as things should be (and every other game boy, and electronic nowadays lol) because i'd really like to do that with a USB-C cable so that i can just share one cable between my switch, phone and game boy lol! is that possible you think?

[@esotericsean]

DomDiggity Thanks for the kind words! There is a really nice custom solution for the GBA on retromodding.com, it’s designed specifically for the GBA. And yeah! It’s totally possible to use USB-C, they sell the same charging board with USB-C or you can but a USB-C connector port and connect it the way I did. These charging boards so allow you play while charging. :)

Hey Sean, The desolder braid doesn't get the job done for removing the power terminal. A solder sucker is definitely the best option!

[@Thatguy101987]

They make a TP4056 board with USB type C on it. Probably would use that instead, just to keep it more modern.

[@Mrbabak100]

I love to watch your videos, they're so satisfying for ma and there's a lot of things to learn from.... I did a great job but i have a little remark about the battery indicator wich is an important part.

[@TheGhettoLife]

I finally completed this mod today. Thanks Sean it was a pretty fun project.

[@JOSHIC]

What battery did you use and where did you get it from? I saw the one he has linked and it is the wrong one.

[@elrolando84]

Awesome video! I was waiting for something like this. Quick question, what gauge are those wires? They look very thin. Thinking on getting some of them!

[@esotericsean]

Rolando84 Thanks! Look for 30 gauge Kynar wire. I think it can also be called wrapping wire, but I’m not 100% sure if that’s the same stuff.

[@GustavoGarcia-jq4wh]

I have 2 GBC and definitely I'll try it.

[@fantasyEXX]

If you waited a couple more years, they now have rechargeable AA batteries using a micro USB that plugs directly into the battery itself

[@esotericsean]

I have a newer version of this mod in a video that uses rechargeable AAs as well :) though you’re right, there are newer options now, but they’re mainly for GBA.

[@powerkane]

that's sweet but in my opinion just because I'm lazy or w/e I would have gotten some sort of connector for the battery, and make it removable for either swapping them out when it dies and you can't charge it or if that battery ever loses its life you can change it easily without having to crack it open. Anyways it is cool and I want a metal Gameboy now lol.

[@georgeindestructible]

You can get a pack of two or two packs of Energizer Extreme Rechargeable HR6 AA 2300MAH(each single cell) and a separate charger for around bucks and get double that capacity. To be exact, in theory, you will get around 57.5 hours on a single charge cycle which is 2.395833333333333 days of continuous non-stop gaming!

[@georgeindestructible]

Add a backlight screen also and you get an awesome gaming experience!

[@Jim55324]

Gameboy Color (used) - $40 Backlit LED screen - $65 Everdrive GB x3 - $65 Micro SD Card - $5 Charging board, USB connector, and battery - $22 Total price to fully mod a gameboy - $197 Expensive, but worth it.

[@bodybody5609]

Finally someone has did it in youtube

[@CutlassCraft]

This is awesome and definitely going to come in handy partnered with the freckle shack :) Would this essentially be the same with the pocket other than the obvious battery size?

[@esotericsean]

CutlassBeatz Yep! Pocket and GBC both use the same voltage so it should be identical. Just a smaller sized 3.7v LiPo.

[@CutlassCraft]

@@esotericsean Awesome! Thank you so much :)

[@eddiebfdz787]

Amazing bro, this Game boy is the best

[@FR099Y]

Nice video as always. Really should have either tried using the original jack to keep the outside nice and schmick. or for the ease of using a phone charger would probably pay to use Type C over micro. Still a really cool mod.
