500A Battery Monitor with Shunt

sean turner on Feb 18th 2023

I brought this so we could monitor what my battery's / inverter was using in power so I could then work out what I was going to need in cable size / fuses etc.. very easy to install and works like it should and helps to understand how much each appliance is using

Great item at a reasonable cost and really helps to monitor my new battery bank. I would have given this product 5 stars but the soldered power lead was almost impossible to insert into the shunt. I had to remove the shunt to remedy this and then it was still difficult. It seems too much solder on the wire into a small connection.

This battery monitor is amazing i don't know how i went so long with out it I have two of them now one in the truck camper and one in the trailer. I can see the amp and watt usage and generation as well. It also gives you an estimated time to empty so you can monitor use and also know the state of your batteries at all time. Highly recommend this and pretty easy to install. Great product!!!

Best advice I ever had

Heard about this from my neighbor who is a full-time vandweller. He actually recommended this to help keep me updated on my battery bank for my van conversion. Best advice I ever had. Highly recommend this
