I run my station from one of my motorcycle AGM batteries, with a smart
charger to keep it up and replace what I remove when transmitting.
The charger is going to be replaced with solar panels if I ever get them up.
I run a 100 watt HF radio on the 28 AH battery plus the uhf and vhf radios.
At 2 amps receive and 17 amps tx my 3 amp smart charger keeps up OK.
