Glenn, as this forum is "Emergency Communications", I have to admit that keeping a battery near full charge is appropriate for near instant deployment. Mine is mainly used for hill top "semi QRO" contest operating, which is a bit different. I have several weeks notice, or at least a few days depending on the weather forecast.
Incidentally, the built-in charge control/protection circuit in my LiFePO4 battery auto disconnects it from charge when near 100%, making "float charging" a bit pointless. From memory, it won't take a charge when the SOC is near 100%, ie you probably cannot top it up from 95% SOC. BTW, the state of charge and Voltage, current, temperature, etc. is shown via a Bluetooth connection to a mobile phone app.
Having spent a considerable sum on a 68Ah LiFePO4 battery, I am keen to keep it in the best possible condition, for as long as possible. It is currently sitting at 64% SOC and is not likely to be needed until the weekend of 3rd/4th October for a UHF contest. It is typically used around once a month for hill top contest operating, sometimes more often for casual operating, depending on the weather and propagation.
Other than the weight, a high quality AGM at 1/3rd the cost of a LiFePO4, works fine for my /P purposes. My old AGM was working well at 6 years old.
