Battery Monitor Advice/Recommendation

[Stewart J]

Last time away noticed battery voltage was getting a bit low so considering fitting a battery monitor to keep an eye on things. Have a 125w solar panel and 2 x 135 ampere lead acid leisure batteries which are coming up 4 years old so getting near their useful life.
Recommendations for a Battery Monitor from you guys would be most appreciated.

To get a true indication of your battery status, will need all of your circuits to be wired through a shunt including your chargers.

I'm using a Victron BMV 712, but if you want to go with a much cheaper option, then this Victron clone on Amazon is good value.
