Batteries not reading each other?

When running into a communication issue between batteries can sometimes be somewhat frustrating. Below is a possible solution for communication issues between batteries.

When coupling batteries in a parallel connection we want the BMS' to talk to each other and this way we will be using a standard 8 Pin LAN cable (CAT 5e RJ45) connecting from the battery link port to the following battery link port BUT there is a catch. In theory these ports are identical in everyway, they are the exactly the same size, same distance apart  and connected to the same circuit board though through vigorous testing with trials and errors we have found that we view the battery link ports as two separate ports one "Battery" and one "Link" below is an example;

With this we will be connecting the LAN cable (RJ45 CAT 5e) on the Master batteries "Link" port connecting to the Slaves "Battery" port. This sequence will continue for all the Hubble batteries in the pack. You can apply this sequence to all our AM range batteries in the field.

Please note that this is a POSSIBLE reason for batteries not communicating with one another, if the communication is still not established please refer to DIP switch settings guide to further troubleshoot communications.
