I am a new ham and am trying to set up a battery operated station. I am not sure how to size a battery for my 100W ICOM 7000, and another battery for my Yaesu 817, 5W. Batteryplus has sealed lead acid batteries named Werker with a trickle charger, from 2.5 Ah up to 15 Ah. I would like to have a system where the radio runs off the battery, and the trickle charger keeps the battery full. Assuming I had two separate systems, what size battery would I need for each of the two radios? Should I keep a meter between the battery and radio to monitor the current voltage? Any help you can give would be appreciated. - Steve KC2TGP
