This is a custom-designed right-angle housing for the Betteri BC01 connector, made to allow closer placement of Marstek Venus or Duravolt home batteries — for example, in tight spaces like flight cases for portable use (small events, mobile setups, etc.).
🛠 Purpose & Background
I made this because I wanted to place a Marstek battery into a flight case and found the original straight connector too bulky for that. To avoid voiding the warranty, I didn't modify the original connector. Instead, I used a new BC01 connector and designed a custom right-angle housing around it.
This housing is not waterproof. Use it at your own risk — I take no responsibility for any consequences.
🔩 Hardware Needed
2x M3 x 16mm screws
A new Betteri BC01 connector (I kept the original intact to preserve warranty)
Cable strain relief is designed for 3G2.5 mm² cable

🧩 Notes
The design includes strain relief to reduce stress on the cable.

Designed specifically with Marstek battery connector clearance in mind.
