I bought this 50AH power queen lifepo4 battery based on an article by emergency communication expert OH8STN . The intent was to provide backup power for my 60 watt station (yaesu FT 817 + Hard Rock -50 amplifier that I built from Hobby PCB. The battery arrived in magnificent shape due to superb packing and had a 50 percent charge(13.18vdc) I ordered a 10 amp charger from power queen (I will review that separately but spoiler alert I love the charger!) So I charged the battery, it comes off the charger at 13.63V but settles down after a few days to 13.34V and remains there as the state of charge. I used the battery to do a morning of FT8 running a current draw of 8 amps for about 3 hours , at the end of session, the battery still showed 13.28V so well over 50 percent remaining! Overall, I am extremely pleased and have no complaints whatsoever.thanks for a great product! Rick Moskovits VE1RNM
