  1. Dave, this is a very interesting report, thanks! I’m curious if your battery load device tracks the amount of energy discharged from the battery. With such a flat voltage curve, it seems that monitoring the actual energy transferred should be more accurate than estimating the state of charge based on voltage. I built a battery box with a Victron shunt that tracks the battery state nicely. With no load on a 46 Ah battery it currently reports 13.15 V and 81% charge. Also, I’ve seen multiple sources recommend that for longest life, operate your LiFePO battery between 20% and 80% charged. It’s OK to charge it to 100% if you really need to, but it will reduce the life slightly by stressing the cells more. This article is aimed more at large battery banks for houses, but has some useful information. https://www.solacity.com/how-to-keep-lifepo4-lithium-ion-batteries-happy/ Craig N7RWB

    1. Hello Craig,

      Thank you for your comment!! No it does not, as that is not what I was interested in. In my case I don’t need that information, I needed to know how long I could safely operate my radio, not damaging the battery. Hence the 20% discharge limitation.

      My main interests in Amateur Radio lie in the RF realm, not the battery operating realm, so I am not delving too deeply into battery usage and operations. Like all things in Amateur Radio, one can go as deep into a subject as one feels is interesting– and I did here…

      Thanks for sharing the link to that article as well, I am sure the folks that are interested in this subject will enjoy it. Also, thanks for commenting!

    1. Thanks Chris,
      Thank you for your comment Chris! I will see what I can find, and add it to this article once I get a change to run some tests. I can say that I have tested a few AA batteries, (non rechargeable), from off brand companies, and was less than pleased with the results. I have also looked at some button batteries, and again, less than pleased. I now only buy name brand batteries…
      Again, thanks for the comment…

  2. Thank you for your work in the batteries. It will be my basis for discharging my 12v 100ah LiFePO4 battery in the shack.

Please feel free to leave a comment.
