I use a 40 Amp Hour Bioenno LiFePO4 battery and a TenTec Eagle @ 100w.  There is more than enough power to run a 100w HF rig all day and not run down.

Lots of people use various brands of 20AH LiFePO4 batteries, good for a morning or afternoon at 100w.  If you do shorter activations the 20AH will last for a few parks.

I bought one of these 20 amp hour LiFePo4 batteries. We shall see how well it does

Over the years I've run my Icom 706, 746, and 7000 using a U1 SLA.

It done very well. Last activation was 84 QSO's and I got tired before the battery did.

I use this same battery powering an FT-891 @ 100watts, along with a laptop, and it out lasts me. Last weekend I ran it all day (0900-1800) and it still had a lot left.
