18650 on a 3DS... mod?

  / opaqueflake   3DS batteries are so difficult to come by. Your only option is to wait for Nintendo to release theirs (or gamble with a pro controller), find a proper li-on one that not only fits, but has the right voltage, or rely on the Chinese market which is a massive gamble in their favor; in addition, it's likely that battery will only last you 3 months at best. And I never really liked rechargeable batteries to begin with. A lot of it has to due with the fact that they're difficult to replace. I've always been a battery user (harvesting batteries for my Game Boy since 89 lol). In my hunt for a replacement (which I gave up in), I noticed that the voltage needed for the 3DS is no different than the amazing battery that is the 18650. And the neat thing is, most 18650's have a higher mAh than the 3DS battery. So I found my solution. My first test was a simple wire to wire connection without the 3DS battery board. No dice. I'm guessing because the pins need to be pushed in (I didn't have enough hands to test that) or the 3DS does need that board in order to function. I could have bought a separate battery board, but why when I have a perfectly fitted one here? I'm tech savvy, but I'm no engineer or hard-modder. I just payed attention in science class and learned how to solder. I ran my test and it worked. Woo-hoo! Now to skip from testing to the final phase. It's actually pretty simple. Since I'm removing XL's case entirely for the cables to run through I needed 3 things. 1.) the board connect to the battery terminals 2.) something to seal it in. 3.) something to hold the cables in place. And my grip pretty much solves nearly all of it. The grip will act as my back case and apply pressure to a block of wood (initially I used cardboard and styrofoam) that's fitted into the 3DS battery slot to provide pressure for the battery board to make contact with the 3DS' motherboard pins. All I had to do was drill some holes for the battery holder's cables to run through and solder the negative wire to the negative terminal of the board. Unfortunately, the positive part could not be soldered. What I did was lift the contact that was being held by adhesive and slip the positive cables underneath it. Not the best solution, but I don't have anything to spot weld it. With the cables routed and the grip and everything else in place, all I needed was to test it(the video). I haven't tested how hot it gets yet, but the 3DS doesn't really draw a lot of amperage to begin with. There aren't really any cons to this "mod". Nothing but my 3DS grip was "damaged" (I drilled 3 holes since I wanted to re-place the battery holder elsewhere). I can still use my original 3DS XL case and a battery replacement. The only real con is that I have to rely on a 18650 battery. But it's pretty simple to swap out a battery. And even though you have to recharge it separately, again, once you swap out a battery, you can charge the other externally. I may not be able to pocket my 3DS, but I don't take my 3DS outside my home. It's uncomfortable to use without the grip for me. But if I really wanted to, I would take it with my grip regardless and the battery will be there to begin with. And that's a grip con which in itself does not have a slot for the stylus to come out (which can be easily remedied by drilling a slot for it to come out, but I never bothered since I don't play stylus heavy games). I already owned a 18650 battery, but they're about $5 a pop. The grip I got cheap off ebay for $8. And the holder for the battery cost me $10 for a pack of 10. All in all, it only cost me $28 to do this which would've been the same amount for purchasing and shipping a 3DS battery from Nintendo. The soldering iron, solder, and flux set I got years ago for $10 from a Frys store, but I'm sure you can spend $10 on Amazon. You don't need to solder the negative terminal, but I did because why not. 18650 batteries range from mAh, but the sweet spot is 3000. I'm using a 2600mAh from a flashlight and that's still way over the 1750 of a 3DS battery. If I really want juice, I can buy a 3000mAh 18650 battery and use that or get a double terminal battery holder that runs in parallel and really go nuts (I might). I was thinking of 3D printing, but I like my jank. And it's likely someone will take this idea and profit off of it (or has been). If I made a kickstarter or something, then I can probably produce this stuff with a custom board and dummy slot, but I'm not sure if the interest is there. Anywho- this was fun, relatively easy to do, hope those who have experience realize that they have options. Cheers!
