[QUOTE="condor22, post: 657925, member: 1932"] When I traded the old van, I returned the 12V system to OEM. As such, I have a Projecta BM320 monitor I can use. A Victron Smart Shunt would be my preference, but hey, the 320 is in the shed, so no extra cost. Note - The BM320 is for Wet, AGM and GEL type batteries, it does not have a Lithium profile. But, it will still measure amps in and amps out as well as voltage to give a State of Charge (SOC). So a non Lithium shunt monitor will still do the job. A little known fact - most monitors will eventually over time, be less accurate re SOC as variations accumulate. The way to refresh them is; Fully charge the battery (any chemistry) until it floats, leave the battery to rest for an hour with no loads or charging i.e. disconnect them all. Then remove the fuse power if used to the monitor, to power it down. Then reconnect everything, good to go. I refresh the BM320 around twice a year. This means a little reprogramming re capacity, date, time etc, a small impost for better results. [/QUOTE]
