Lynx Smart BMS

The Lynx Smart BMS is a dedicated Battery Management System for Victron Lithium Smart Batteries. There are multiple BMS's available for Victron Smart Lithium Batteries, and the Lynx Smart is the most feature rich and complete option. Its main features are:
• Built-in 500A contactor used as a fallback safety mechanism and also suitable as a remote controllable main system switch.
• Battery monitor, indicating state of charge percentage and more data.
• Pre-alarm signal: provide a warning before the system shuts down due to for example a low cell.
• Bluetooth for use with the VictronConnect App, for setup and monitoring.
• Local and remote monitoring using the Cerbo GX.
• The Lynx Smart BMS is part of the modular Lynx Distribution system.
The instruction manual is the most complete guide to wiring up the Lynx BMS. I made the following video to explain everything in an easy to understand way but if you see any discrepancies the manual takes precedence.

Good info. I’m going to do some cabinet work and rewire my system. It takes some planning to get it all to fit neat and compact.

Can you tell me which relay is controlled by the soft switch on the Cerbo GX GUI? It's called Relay 2 but I'm not sure which device its controlling. There are relay outs on my Cerbo, Lynx BMS, and Inverter/charger.
