Great Monitor with Bluetooth feature.

Can I run my Optimate 6 smart charger's negative/ground through the negative of the Victron Shunt..

or..


Should  I rather keep it connected to the Battery Negative Terminal directly?

Have a 100ah 12V Lead Crystal + Victron SmartSolar Charge Controller MPPT 75/15 hooked up.

still got my training wheels on! LOL. 

Simple little "portable" battery bank setup so nothing complicated really.

Thanks!

Hi OCD75

The BAT terminal on the Shunt should be the only thing connected to the Battery Negative. All other "negative" connections (loads, chargers etc.) must be connected to the "Load" side of the Shunt. If you don't do this, the BMV712 shunt cannot properly measure current into/out-of the battery - and will then give an erroneous reading for the State of Charge.

Knew my gut was right but thanks so much for clarifying for my pea brain! 😅
