Summary

This box is designed to keep a spare CityCOM BMS cell module safe in a semi-rough environment like on board your CityEL.

This is designed for a module for the 100Ah version from 2009. The inner dimensions are 105 x 40 x 34 mm to leave space for an antistatic bag.

I am using the version 1 box myself and haven't gotten around to testing version 2 before deciding that the extremely tight fit (think screwdriver-needed-to-open tight) is actually perfect for the purpose. Version 2 kept around in case it turns out to be of use to someone else. Also, Sketchup 15 source if you want to customize.

The box fits one of my spare boards with the cable connector arms in the closed position and packed in an antistatic bag. I advise you to measure your own board before printing since I suspect they may have been produced in different sizes.
