10s2p Battery Case for MPT-7210A
Description
#The Idea I wanted to have a case where I could put a 10s2p battery pack that has an MPT-7210A solar controller mounted to the top. At least a few years ago, this was a method for charging on the go with OneWheel's. The MPPT acts as a voltage and current regulator to charge the OneWheel (or any PEV). So the 36V from the battery gets boosted to 63v at (up to) 3 amps. You can find more details here: - https://theboardgarage.com/articles/diy-power-bank - https://onewheel.wiki/Charging_on-the-go - https://www.youtube.com/watch?v=tbqWFVm9cD0 #Design The box was designed to have a little bit of play on all sides of the battery. You can pad this out with packing foam or anything else you think would protect the battery while riding. I wanted to be able to get into the battery as well as remove the MPT if I wanted to. So the lid and MPT are mounted using M3 heated inserts. This allows for repeated maintenance without threading straight into plastic. Stuff You'll Need: - M3 Heated Inserts (5mm length) - M3 Screws (4x 6mm, 4x 10mm) - PETG (cause better durability) - 10s2p Battery (google it, they are used in "hoverboards") You can use either lid on either box. Its all the same. I am using the one with hexagons on top because [they are the bestagons.](https://www.youtube.com/watch?v=thOifuHs6eY)... And they also act as a vent for heat.
