The installation is on a boat located in the Central Coast of NSW, Australia. The customer purchased 3 x lithium 12 volt, 100ah batteries, smart BMS, BMV712, smart battery protect. An existing start battery was in existence. The Victron gear is for onboard services, radio, cooker, lighting etc
There is a separate isolation switches for both starter battery and lithium batteries. When I disconnect the lithium batteries the system shuts down. All good.
When I disconnect the starter battery alone the system shuts down also even though the lithium batteries are connected and on. Is this normal behaviour?
