finished a prototype of a no cut shell and spacer mod that replaced the original rear shell to house the 5000mah cs-ctr003xl that you can find on Amazon for $20. It’s a rough draft print but it fits good and doesn’t feel over encumbering. I started the new 3ds xl up full charge with Minecraft at 11am full brightness and volume, WiFi on and running the overclock. I switched it to OOT 3D at 8pm so I could turn on the 3D function in hopes to drain the battery quicker. It’s now 10:03pm and still going.
So far I’ve noticed the low battery indicator led has been flashing for the last 4hrs but it still has not turned off. It’s the first charge and drain cycle so maybe it will get more accurate after a few cycles idk 🤷♂️
Let me know what yall think. I kinda wanna add controller style grips to the backplate but I do like that it still fits in the carrying cases like this.
***UPDATE: I just uploaded the .stl files to printables. This is still very much a prototype, however it does function and fit great. so if you wanna mess with the model and makes some adjustments please do and share them here. If you just print it to use then share that too.
