4.3 Install Instructions
4.3.1 Numbering Batteries
Before connecting the battery sensors to the batteries, label and number both the
battery sensors and batteries clearly.
Battery String
1 2 3 n n n
+ +
1 2
• The first battery, or battery NO.1, must be the first one on the string's positive
terminal, the NO.2 is the battery following the NO.1 battery, and so on:
• Multiple strings with separate ports and sensors in parallel:
• Each string starts with 1 and continues to the last battery in the string.
• Each string requires a string sensor.
• Example: 120 Batteries consisting of two strings of 60:
• String 1: 1–60 (addressing).
• String 2: 1–60 (addressing).
NOTE: All string sensors must have dierent addresses (starting at 241 and
incrementally increasing in order in configuration up to address 246).
• Multiple strings that use the same port (maximum two strings) with sensors
in series:
• String 1: 1–30 (addressing).
• String 2: 31–60 (addressing).
• Second string sensor (has an address dierent from the first).
• The last battery is the one attached closest to the string negative terminal.
Number the batteries according to this practice.
NOTE: The BMS is a multiple string system. COM ports 1–3 on the BCU are capable of
supporting two strings (six strings maximum) for each COM port.
