Battery Monitors, Part 2—Recommended Unit

Update December 2020

If you don't already have an amp counting monitor, see my update at the end of the last chapter before reading on since there is now a better way to get this done without going through the next two chapters of aggravation. That said, I have left said chapters up for those who already have amp counters and want to know how to make them work properly.

In the last chapter I looked at the two types of battery monitors—volt measuring and amp counting—and concluded that which type we choose is all about how anal retentive and technically nerdy each of us is.

Now here's a test for you: Since I chose an amp hour counter, which type of monitor is right for anal retentive nerds? (If you fail this test you have not been reading my stuff for long!)

Yup, this post is for card-carrying nerds with a side interest in being a control freak. The rest of you can stop reading now, go buy a volt measuring monitor, and live happily ever after...OK, I can't guarantee that last part.

Still with me? OK, put on your propeller hat and let's dig into which amp counting monitor to buy and why.
