GPi case NIMH charging circuit install/setup.

[@lampsonnguyen9425]

I just ordered one. Looking forward to mod mine

[@NelsonFluckz]

LADDA are Enelopp / Panasonic. All from the same factory in Japan.

[@AkumaMods]

That's what I keep hearing

[@workingmanbh]

@@AkumaMods from the articles and videos i saw, yes, they are like the same, same factory. Charge and discharge curves, and real charge are the same, almost.

[@AkumaMods]

@@workingmanbh that is correct, it's one of the reasons I went with them

[@MagicTukan]

Eletechsup 1A 3.6V 3S

[@A7mag3ddon]

Which is the better mod in terms of battery life this one using 3x ladda 2450 batteries or the lipo 3.7v 4000mah battery mod ?

[@WhatsUpHiro]

Is 3.6v sufficient for the Pi Zero? I saw another video that used a charging boost module to get up to 5v. Also, what kind of battery life could I expect out of this setup before I need to recharge?

[@AkumaMods]

Booster is not needed for one is built into the board. If you use a booster it'll blow up the onboard booster. That is not a smart thing to use....as for play time I get usually 2 1/2 hours of play before I call it quits so never really went past that but I've heard they have about 3 hours of hard use out of them

[@pinobarbareschi6452]

hi brother congratulations for the project I wanted to know I have a 5000mah battery would it be good for the GPi Case? thanks congratulations again

[@AkumaMods]

As Long as you get the dimension to see if it'll fit then yes it will be ok

[@pinobarbareschi6452]

@@AkumaMods it has the same dimensions as the battery cover.....so with the 5000mah battery I'm fine, isn't it burning? A thousand thanks

[@AkumaMods]

@@pinobarbareschi6452 no shouldnt be a problem. The battery monitor should make sure it charges at the correct currents but just make sure it's the right type of battery. This tutorial is for NIMH batteries. However there is a Tutorial for LIPO batteries

[@pinobarbareschi6452]

@@AkumaMods in what sense is the right type of battery? but by any chance can you show me the tutorial in the video

[@pinobarbareschi6452]

@@AkumaMods maybe recommend me a better battery

[@BrianCzapiga]

Depending on the charging circuit, you may only need to connect one ground. On the NIMH charging circuit that I received, the grounds on the input and output were bonded, so during install I only needed to connect three wires total. (V+, B+, GND)

[@AkumaMods]

This is correct the one I use is a straight in line I just wire it up as precaution to make sure everything is working as intended and I'm not worried about something possibly blowing up because I didn't have the board in line

[@BrianCzapiga]

@@AkumaMods It's good practice to probe the pads you are connecting. For instance, I used your video as reference to get the initial pads, but when I was on the workbench doing the install I didn't have the video in front of me, so I used a multimeter to check connectivity for ground and the actual pad for the 5v (continuity check from the barrel socket.) It's just one more thing to check when wiring to verify the grounds are connected on the charging circuit.

[@djmcmkl]

Iv done the mod. My problem now is when the red led starts flashing I connect it to a power source and the it reboots. If only does it when the led is flashing. I'm using Duracell 2500mah battery's

[@AkumaMods]

Probably because there is not enough power to charge and play at the same time. The circuit I'm using doesn't provide enough input power to do a play and charge setup. It will do a play and charge but it's only charging about 5% capacity when playing. Kind of the same premise as jumpstarting a car. Usually doesn't start right away. Needs some time to charge

[@Coldsteak]

what are you 3d printing bro?

[@AkumaMods]

I think I was printing the wall mounts for my laptop

[@santiagomerinovaca6002]

When all is fitted and gpi case closed with this mod, there's any visible led that helps to see if batteries are charging?

[@AkumaMods]

You should be able to see the red charging light through the contrast wheel side of the case. Once it is done the light will go out

[@kinggreene]

its Nickle metal HYDRIDE not hydrate

[@santiagomerinovaca6002]

Where i can found the energy power cable in L form you are using ?

[@AkumaMods]

I use silicone wires 28 awg

[@AkumaMods]

They are on Amazon

[@dankjosh]

So I tried the mod and it does seem to charge the battery but not fully. After about an hour or so the unit stops charging as indicated by the LED light not emitting. If I unplug and re-plug it will begin charging again, but again after an hour or so, it will stop charging again. I tested the on screen time of the device after a charge the unit only stays powered for about an hour or so before dying and these are with new 1.2 volt 2400 mah batteries. Is there a reason why the unit would stop charging?

[@AkumaMods]

Something might not be wired correctly. Are you using one of my circuits or the Chinese ones?

[@dankjosh]

@@AkumaMods I mean it all comes from china doesn't it? but using these I found off amazon www.amazon.com/gp/product/B07WKF3S3J/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1 I picked the 3s which should be enough to power the 3 batteries and followed the setup in the video.

[@jmerey]

@@dankjosh Did you resolve this?

[@dankjosh]

Jamie Reynolds yes. Removing and resoddering did the trick. Battery life isn’t what I was expecting compared to the moddable battery mod akumamods has posted in another video but it does work.

[@sinisa.banjac]

@@dankjosh Can you say more about battery life? How long does it last?

[@kasen581]

Can someone help? Whats is the size of the barrel of the charging cable? Mine came with the incorrect size

[@AkumaMods]

The charge cable is 0.7. I sell angled charge cables for $12 shipped worldwide on my AkumaMods shop on facebook

I can't use mine Gpi with batteries, because mine 2r2 coil is smoked away. Does anybody know what kind of coil this is and where i can find some?

[@AkumaMods]

I can see if I still have a few extra coils laying around. Or if you want to send it to me for a repair I could do that too. Shoot me an email at [e-mail]

[@lagratm297]

@@AkumaMods thanks for the fast reply. I will send you an Email tomorrow. its now 11pm at mine and i'm really tired. thanks again.

[@AkumaMods]

@@lagratm297 sounds good bud. here to help. Since your at 11pm now my guess is your I'm or at least overseas so I'll see if I can find some battery springs to get you up and running since sending me your unit might be a bit costly to me and to ship back to you

[@jeroenkrieger]

Will this mod work with an original Game Boy?

[@AkumaMods]

Unfortunately this circuit was specifically made to only use 3 AA batteries. Now I do have the ability to use a single cell or dual cell as well but not a quad cell currently
