M8 circular connector Male/Female 3 pole cable 5m (bag of 2)
The Victron Energy M8 Circular Connector Male/Female 3 Pole Cable 5m (Bag of 2) is designed to extend communication links within Victron lithium battery installations. It supports stable data transfer between key components in both Smart BMS and NG BMS systems. When accurate information flow is required for monitoring, protection, and battery optimisation, this cable provides a reliable and tidy solution.
Each cable features a matched male and female M8 circular connector. These connectors are engineered to create secure contact points that resist vibration, making them suitable for both mobile and static environments. The 5 metre length allows you to route communication connections through larger energy storage layouts without strain on the connectors. Whether you are fitting equipment into tight spaces or linking battery banks across cabinets, the generous length provides welcome flexibility.
Supplied as a bag of two, this pack offers value if you need several extension runs or simply want a spare on hand. The three pole configuration is optimised for Victron BMS communication signals so your battery system can report its status consistently to control hardware. This supports charge regulation, temperature oversight, fault detection, and other protective functions that keep your energy system safe.
In addition to function, the cable is built for durability. The connector bodies are robust and designed for repeat mating cycles during installation or system upgrades. The cable jacket protects internal conductors from wear caused by routing around frames, panels, or external housing edges. These qualities make it suitable for professional installers who require dependable accessories as well as committed DIY users.
This cable is ideal for anyone expanding an existing Victron setup. It can also be used during initial builds to provide tidy cable runs between batteries, BMS modules, and management displays. By preserving signal integrity, it helps ensure consistent performance and clear monitoring feedback from the battery array. If you are planning upgrades, this accessory provides an easy path towards better layout flexibility without compromise on communication quality.
Overall, the M8 Circular Connector 3 Pole Cable offers convenience, dependability, and compatibility with core Victron BMS products. Its balanced length, secure connector design, and pack quantity support efficient installation. For those aiming to improve cable routing or maintain tidy control wiring, it is a practical accessory worth including in your system design.
