If you want to go belt and braces I guess you could apply a dab of locktite on the screw to make sure it doesn't loosen off over time with vehicle vibrations?Īnyway, that is it. I had to extend the 2m cable that came with it, using a 26/4 shielded cable that seemed to match up quite well with the factory cable. And my inverter is rated at 1200 watts continuous, with a 100 amp breaker as protection. AiLi Battery Monitor from Amazon I elected to save some money and install the sub 40 AiLi Battery Monitor from Amazon (Chinese) vs the Victron or other more expensive options. My system is a12 VDC 220 amp-hour lead-acid battery source. I am going to purchase one of these units. To resolve is very simple - just tighten up the screws! Now I have never had this problem before so I would not say it is common, but something to watch for. Size: 8-80V,0-100A Verified Purchase Some reviewers are saying amp hours are limited to 100 amp hours but if you read your manual you can set the limit by holding the center button down for 3-5 seconds and can go up or down with the left and right arrows. AiLi Battery Monitor Voltmeter Ammeter Voltage Current Meter 8-80V 0-100A. (initially I thought it could have been electrical noise interference from the BMS or internal Battery Heater but we eliminated that as a cause). My portable solar charges my batteries, positive to the positive battery terminal and negative connects after the battery onto my negative/ground shunt connection. If either of these screws are loose this problem can occur. In my setup, I have two 6v Trojan T-105s wired in series, and a AiLi Battery monitor wired using a shunt as designed. The -ve connections come from the Shunt of course and this is connected via the screws that secure the little PCB to the shunt - the screws you see on the different shunts above. The problem was that the -ve connection to the Monitor was a bit poor and that caused the monitor to misread. These Monitors come with one of three different Shunts - image below (the one in the video is the 350A version) This is obviously not correct and this is the reason. Have we discovered the electrical equivalent of Perpetual Motion? Sadly not. If you pause the video and look at the installation you will notice that there is this charge current happening even though the only thing that is connected to the Negative Terminal is the Shunt and only thing on the Positive Terminal of the Battery is the shunt again.
