You will be fine.

Our 4 cell 300Ah LiFePOe battery has been both powering our motorhome and starting the 3.9l turbo diesel engine often multiple times a day for 10 years of fulltime travel.

The 500A Victron SmartShunt and series installed 400A rated Junctek shunts still look like new.

Cool - ya went and installed it yesterday - its peeking at 375 even has the intake heater and air bags kick on. Its always parked indoors and pluged in but guessing maybe in winter I expect it to crank and bit harder.


Are the 1000A and 2000A stunt options for installs where they have invertors constantly drawing to the size.

@Christopher

Just out of interest what information do you get from the shunt on the starter?

I'd be interested in a screenshot of how it shows up in VRM if you are connected?
