Sometimes the battery that comes with an item just isn’t big enough. For example, the 8Bitdo Zero mini bluetooth controller; this controller can be found easily for around $7 and works great with pretty much anything. The problem is that the included 180mAh battery always seems to die at the most inopportune moments. Why not use a spare 18650 you’ve got lying around to upgrade that capacity to something like 2200mAh?
As a bonus, you get those sweet techno-jank points to brag about.
Not much to this one. The longest part was waiting for the holder to finish printing (about 40 minutes). Some glue and solder wrapped up the rest. Easy 10x battery life! Additionally, it’s actually a bit easier to hold now with my big people hands.
