Cheap Battery monitor.

[sooty_10]

Not that I am aware of. If you were planning to run a winch off the battery(s) being monitored going for the 500amp one would save having to bypass/reset the monitor as I have to do with my 100A monitor.

My aux battery is earthed to the chassis and also has a direct earth to the start battery, with this shunt on the negative side would it simply display the complete vehicle battery (ie. both batteries) capacity?

I also have 6 B&S twin core going from the aux batt to the rear of the vehicle to a distribution fuse block and earthed to my rear drawers with a stud for easy earthing of rear accessories. I'm just trying to get my head around where the best spot for the shunt would be, and if it actually makes a difference to what it reads/sees in terms of amps etc.

If I put the shunt inline with the 6 B&S negative, it would be pointless having a higher amp shunt than the capacity of the cable?
Or do you simply place the shunt in the biggest negative cable attached to the battery, such as chassis earth cable?
