First of all, hello!
I recently installed this screen into my GBA. The GBA is 40 pin motherboard.
According to a tutorial on Funnyplaying i needed to remove "C54 capacitor" if its 40 pin motherboard (which it is) from it. (i don't know why, what this accomplishes, and its optional, but i followed tutorial even though it didn't said why to remove it)
And i also did this battery mod, except i didn't used the battery in tutorial, i used two switch joycon batteries (3.7V / 525mAh each) connected them in parallel to get 3.7V / 1050mAh
So now i have backlit screen and lithium batteries inside my AGB.
Here's the problem and reason i'm writing on forum:
I can charge the battery using 5V/1A usb-c sharger from my phone, it charges fully in about 1.5h's.
It plays pretty well also, everything is great, except when i turn off the GBA and leave it for about lets say two days, and try to use it, its eather almost empty (red light) or empty completly.
Cant remember but basically its 2,3,4 days being OFF and its empty.
On other hand, my GBA SP, can have charge for months with it being OFF, and when i decide to play it after a month it still has plenty of juice, like i charged it jesterday.
I cant figure whats the problem, but i did poked with multimeter on batteries ends to check DC voltage, and it is disctarging slowly at rate of... well lets say like this
i checked the battery at 01:30 and it was showing 4.084V, than when i woke up at 09:00 and checked it it was 4.078V and now its 16:15 and its 4.075V.
I dont understand what can be draining it when its turned off by the GBA switch. I also have 3 of these charging boards, i tried another and same thing.
Any advice, help, guide how to test and what could be the cause?
