The original battery compartment in this unit has almost no internal space. My battery even arrived with puncture holes, likely due to the tight fit and its proximity to the high-voltage section. This raises safety and reliability concerns, as the insulation and clearance appear insufficient.

This 3D print allows you to relocate the battery outside the enclosure, improving safety, preventing damage, and extending battery life.
