I can't believe how light this battery is compared to a similar sized lead-acid battery. It is very small and lightweight for its current capacity. I will be using this to power my Icom IC-705 amateur radio transceiver when I am working portable while camping or doing Parks-On-The-Air (POTA) work to activate a state or federal park for a day.I plan to use a few of these when I plan ahead to be on the radio for an entire weekend since they are light and therefore easy to carry from my car to my portable station in a park somewhere.The weight is just under 2.5 pounds. My battery will maintain a more or less flat battery voltage of about 13.8 V until it is almost entirely discharged. Compare that to my lead-acid batteries I also have set up for ham radio use, where they start out at 12.6 V and slowly lose voltage as their capacity wanes. This is where LiFePO4 batteries shine over the other type of battery. As they lose capacity, the battery voltage remains fairly constant.That's important with many ham radio transceivers, which stop working right when the voltage dips much below 12 V. When a LiFePO4 "12 volt" battery is fully charged, it will read about 13.6 V. When it is 80% discharged, it will still read above 12 V, actually, around 12.8 V, higher than a fully charged lead-acid 12 V battery. So these drop only about a volt over most of their capacity range, and with only 20% of their capacity left, they still have a higher voltage than a freshly-charged lead acid battery! Yes, they start out with a higher voltage, but the discharge curve is nowhere near as steep. This means that, even at a 90% discharged status, these will still have 12 V across the terminals, so a ham radio transceiver will be happy and not shut down due to low voltage.
