Posted on July 18, 2021 by Bob Beatty

In April of 2013, I purchased parts to build my own 60 AH LiFePO4 battery.  Back then it cost about $440 – about $100 more than a comparable battery can be purchased for today.  That said, it has served me … Continue reading →

A charger for LiFePO4 batteries

Posted on February 11, 2021 by robert

In an earlier post, I described a rather inexpensive 16 AH LiFePO4 battery.  I’ve used that for my last three activations, and so far it works as expected.  A few folks have asked me “What charger do I use?”.  I … Continue reading →

Typical LiFePO4 Battery Use for 100-watt SSB

Posted on October 25, 2020 by Bob Beatty

Because of my POTA activity, I’ve been able to keep track of my current consumption as I run my IC-7000 in SSB.  It is a fairly typical 100-watt rig, pulling about 1.4 Amps in RX at listening volume, and specified … Continue reading →
