The Victron M8 Circular Connector Male/Female 3-Pole Cable is designed to extend battery management system (BMS) communication cables in compatible Victron lithium battery installations.
Available in 1m, 2m, 3m and 5m lengths, these cables provide flexibility when positioning batteries and BMS equipment within campervans, motorhomes, boats and off-grid electrical systems.
Each pack contains two cables of your selected length.
Victron M8 Circular Connector Cable for Lithium Battery Systems
The Victron M8 Circular Connector Cable provides an extension for the communication cables used with compatible Victron lithium batteries.
These cables are suitable for Victron Lithium Smart batteries connected to a compatible Smart BMS. They can also be used between Victron Lithium NG batteries and their corresponding NG BMS.
Each cable features a 3-pole M8 circular connector, with a male connection at one end and a female connection at the other.
This allows existing BMS communication cables to be extended when additional length is required.
Available Cable Lengths
Choose from four available lengths to suit your installation:
-
1m: Suitable for installations requiring a short extension.
-
2m: Provides additional flexibility when positioning equipment.
-
3m: Ideal for installations requiring a longer communication cable.
-
5m: Suitable for systems where greater separation between compatible components is required.
All four options are supplied in packs of two cables.
Designed for Victron Lithium Battery Communication
Reliable communication between lithium batteries and their BMS is an important part of a correctly configured electrical system.
These genuine Victron extension cables allow you to increase the distance between compatible components without replacing their existing communication leads.
Their male-to-female design makes them a practical accessory for new installations and modifications to existing lithium battery systems.
