BMS RJ45 Straight Cable 3m for Battery Communication | Voltacon

This Voltacon BMS RJ45 straight cable is 3 metres long and carries BMS communication data between lithium batteries, or between an inverter and a master battery. It uses the same 8-pin RJ45 connector as a standard ethernet cable, but wired with a pin configuration specific to BMS data transfer rather than network traffic.

Key features

• Length, 3m straight RJ45 8-pin cable
• Battery-to-battery, for BMS communication between battery units
• Inverter-to-battery, for communication between an inverter and the master battery
• Compatibility, works with Pylontech, Dyness, Voltacon and Pytes lithium batteries
• Not standard ethernet, wiring differs from a normal network cable despite the shared connector

Applications

Used within a battery bank to link individual units for BMS data exchange, and to connect an inverter to the master battery in a lithium storage setup. Suited to installers building or expanding multi-battery systems where correct BMS wiring matters as much as physical connection.
