Yes, I plan to get some of Tom's battery monitors, I just haven't had a chance to get over there since he got them working. I might be able to go over there tonight, if he's around.
For those who don't know, our friend Tom (who you see in many of my YouTube videos) is an electrical engineer who has a homebuilt AC Dodge Neon.
He's designed some simple battery monitors based on a multi-LED bar. Essentially, it's a real-time, mini bar graph of your battery voltage. Each little pc board of LEDs shows the voltage of 4 individual batteries.
I am also interested in using these monitors in my home battery backup system. Currently, the 48V UPS is using two parallel strings of of four batteries. By using the battery monitors, I can see if any individual battery is bringing the rest of the string down.
