HXT4mm charge marker

thingiverse

I plug in these charge rings onto the battery contacts of lipos with HXT-4mm connectors once they're charged up and ready to roll. You know a fully charged battery by its charge marker - it's just plain visible. By blocking the contacts, these rings prevent accidental disconnections before deployment, making them easy to use. With this setup, I don't have to worry about forgetting to take out my batteries' charge indicators when using them. Keeping track of which lipos need recharging after a mission is child's play with this simple system in place. As an improvement idea, I'm considering printing charge rings in different colors so I can easily tell apart the batteries that are charged and ready for use versus those that still need charging during storage. It sounds like a no-brainer to me right now, but I haven't gotten around to making them yet. One major advantage of using these printouts as markers is just how fast they come off my 3D printer - no time-consuming production needed! And it doesn't hurt that they look professional when printed at 0.3 layer height, giving a crisp finish without compromising their functionality. For reference, you can find the image samples online. If HXT isn't your connection of choice, I also have variants designed for XT60 connectors and JST connectors which are readily available for download - no fuss needed!
