Victron EnergyBMV-712 Smart Battery Monitor (Grey)

A great improvement on our previous method of working out what our batteries were doing. Not easy to fit, and not a staightforward job with a lot of adjustment needed to the wiring layout in our case at least.Having got through it and installation complete, I would be without it for its clear information on what our charge state is.

Easy to install, and works perfectly, data cable is very long and in my case I only needed about 4’ so it means a large bundle of cable in battery compartment so I’m looking for a shorter cable which would be great if this was an option on purchase, apart from that I’m happy with it

Arrived on time, easy to install and does the job.

Pricey but works well

After installing a brand new expensive AGM battery bank in my camper , I was at my wits end for a few weekend trips worrying about keeping my state of charge above 50%. When I installed this it gave me peace of mind. I don't know what the other reviews are fussing about Bluetooth coverage for.....I have no problems....i can check it from GREAT distances. It can be tricky to get connected at the start, but bear with it and keep trying and checking you're doing everything correctly, because when you do , you won't believe how accurate and functional it is. Highly recommended quality product.

A neat product reading out your rate of charging or draining your battery bank using the shunt supplied and how much charge is left. Plus ammeter and voltmeter and volts for second battery.
