Here is the Xiaomi Pro2 spacer with 35mm, which can comfortably accommodate a 20s3p 21700 battery pack + Vesc. An appropriate screwable cell holder is included in the profile. The BMS should have a maximum thickness of 15mm; we recommend the JBD SP22S003B. A total of six threaded inserts are required: 4x M3x5mm and 2x M3x6mm. The charging port requires a XT60 built-in socket that can be bought over aliexpress. All necessary STL and STEP files are included.

Best regards,
CEPP Team
