Hey everyone! Not sure who's been reading my updates but heres another one about upcoming changes on the mod I'll be testing this Sunday as well as restating where I'm at. If you haven't read my last update then let me start there.
I have wired up in my back housing a usb type C breakout board and a rocker switch to my batteries to bypass the vita as the source of charging. The positive lead from the battery and the vita is interrupted and the switch is here. When you open the switch (off position) it isolates the batteries from the vita allowing them to charge safely wile removing the possibility of grounding though the vita and frying the device. This also acts like I'm physically pulling the battery without opening the device so thats a plus.
Now that recharging is possible without the vita as a limitation this mod is amazing! My only thought moving forward is lifetime on the batteries that are parallel. From research I shouldn't have too many issues as ive taken every step to make sure they are the same as well as physically checking voltages with multimeter before last solder job. With that said i have a large 8000mah battery coming in 10/11 that i will rig up on 10/13 and will let everone know how its working by next week!
I love the enthusiasm of some people who have tried this and say its not possible and dangerous BUT I haven't ruined a single battery or any parts of my vita yet by simply doing research on the current bottleneck and using knowledge I have in digital logic and circuitry to bypass the issue and address it! I will be making another post if this 8000mah battery works or not showing the wiring and explain again how it works.
Much love to the vita community!

All parts used (rocker was purchased at local shop so thats just matching specs)

Definitely, you just need to convert the 12v into a trickle charge. There are many ways to do this, some more efficient than others. There might be a AA charger that runs off of 12v, might have a cig lighter input and be in automotive sections. Let me look on Amazon and stuff.

​

• Here, this will do you just fine. does your solar have bare wire leads, or is it USB only? If you have wire leads, just cut the cig lighter off, and connect the positive and negative together and you're good to go
