You might be able to find one with a micro USB port on the side (or both sides if it exists) of the actual battery. Then you'd just take off the cover and plug it in. For mine, since it's on the bottom I can charge it with the battery still attached to the bass, but it has to hang off of the guitar. It's not a big deal though. https://a.co/d/0axzWrJt this one is kinda what I'm talking about. A USB port on the wider side of the body. I guess it depends on how the battery fits into your bass. Just keep it for home use I'd say. Other comments say it causes unwanted noise. I haven't experienced that though. Most of that disappeared when I got actually good guitar cables.
