For anyone interested in powering a small HF rig or a 2m/70cm mobile rig in the field, here's a pretty low-cost solution that, so far, has worked great for me. This Miady 12.8v 16Ah LiFePO4 is a bargain at $45.99, and this 12v 2A charger is also affordable at $20.99. Total cost with shipping was under $75. That's a pretty good price for a 16Ah battery. The weight is just under 4 lbs.
I've used it with my Xiegu G90 HF radio as well as my BTech UV-50x2. The G90 puts out a max of 20W so I can easily get a full day's use out of a charge if I'm not doing a continuous duty-cycle (digital or CW). The UV-50x2 puts out up to 70W on 2m, so not as long a run time there but still good for a fairly long period of time. Setting the rig to low power (30W) gets me a good long time - most of a full day.
