WEST MOUNTAIN RADIO COMPUTER BATTERY ANALYZER IV WITH AMPLIFIER

Greg Gimlick reviewed the West Mountain Radio Computer Battery Analyzer (CBA) IV with Amplifier for us. Here is what he had to say:

If you fly electrics, you already know that you have a lot of money tied up in batteries of various sizes and chemistries. I’ll admit that I’m a focused on keeping track of my packs and how they perform over time. I updated to the latest version of the CBA IV and added the extended software package to include the extra features.

The optional extended software license provides all of the features of the standard version, but adds four different types of tests: duty cycle, constant power, multiple discharge, and constant resistance. The results can be graphed as voltage versus amp hours, watt hours, minutes, or Ragone depending on the type of test. I also needed it to use the 500-watt amplifier.

I’ve lusted for this combo since I first saw it and I’m not disappointed in the decision to get one. This device allows me to accurately replicate the real-life applications where my batteries are used. That stated, testing at maximum ratings isn’t necessary to tell if a battery is good or bad.

Battery discharge performance graph

A 1C discharge will tell you if the battery is meeting capacity specifications. That should be all you need to determine if you can continue to use a battery. Testing at maximum discharge ratings is only necessary to tell whether a battery is safe at those ratings, how much the cycle life is shortened, or if it will overheat and sustain damage or ignite. Caution is advised if using the amplifier and higher-than-recommended discharge levels.

All of this connects to my shop computer to track the packs, and even prints labels for each pack if desired. One of the beauties of this package is its ability to overlay new tests on old ones to get a perfect picture of how well they’ve stood up over time. It also allows me to have a constant current discharge unit that will ensure accurate and repeatable tests every time. This is the first discharge device I’ve seen that guarantees accuracy and log data for future reference.

As always, you should never leave a battery pack unattended while it is being tested. The CBA IV and its software have many built-in safety features, but caution is key. If your computer is set to go to sleep, or for some reason it crashes, the CBA IV will automatically terminate the test and shut down to avoid any errors.

I highly recommend the CBA IV for anyone remotely interested in how their usage affects their battery packs. It has allowed me to identify packs more suited for less-strenuous applications and continue using them rather than lose an airplane or helicopter because I didn’t notice the gradual decline in one cell. Think of the CBA IV as good insurance for your aircraft.
