Shielded comm cable
Instructions on using shielded cable to connect adjactent cell boards
In rare cases, in electrically noisy environments, when connecting Cell Boards together, if the length of the communication wire would be more than 2" (50 mm), and/or it cannot be lain along the high current path, you may need to use a shielded cable instead.
Before using this solution, first follow the noise abatement procedures, which usually are sufficient to eliminate problems due to noise pick-up.
Li-Ion batteries are dangerous!
Unfortunately, we do not have the resources to teach all of our clients proper assembly procedures, which are essential for a succesful project. What we can do is pass along this info to you:
In this case, each battery box was divided into 4 sections. Sections are separated far enough that each section should be its own bank. However, there would have been a total of 20 banks, and the PRO master can only handle 16 banks. Therefore, the user decided to use two sections per bank, and to extend the orange communication wire between the two sections.
Unfortuntately, this installation also used a particularly noisy motor inverter (UQM). This resulted in noise pick-up, which occasionally resulted in bank communication errors.
The solution was to replace the extended orange wire with shielded cable.
