I've got a Yaesu FT-710 Aess 100-watt transceiver I want to try and use for my first POTA adventure.
I'm trying to research portable power systems to use with such a rig.
1 - What battery would you suggest?
2 - For charging the battery at home, what charger would you suggest.
How much 'battery' you will need depends on how you like to operate, which may change for you since you are getting started with portable POTA (and maybe WWFF someday).
I use a 100w radio for 3 hours of pretty much non-stop CQing on CW from parks (200 QSOs), and it usually takes about 20 AH from the battery. My wife likes to operate SSB, she can be at a park, making 200 QSOs and it uses the same, close to 20 AH, with non-stop calling CQ and working people.
So if I had a 20 AH LiFePO4 battery, it would be dead every time with no reserve. I have a 40 AH Bioenno LiFePO4 battery, sometimes we use 22 AH from it and have never had to worry about not having enough battery for the day.
More casual operating (less CQing and more tuning around) would use less power from the battery, of course. Many people with 100w radios use 20AH LiFePO4 batteries and are happy...
For a charger, if you get a name-brand LiFePO4 battery they usually come with the correct type of charger needed.
I wouldn't recommend a Gel Cell or AGM type battery, the voltage drops faster than LiFePO4 and you can only use about half of the rated Amp Hours.
Others with solar setups will have to tell you about those :-)
