Mid power Mastr II stations used 15 amp factory power supplies...100w stations used 30 amp power supples.. so.. probably less than 15 amps.. maybe 10-12..
Reducing the voltage to 12.8 from the batteries will significantly lower the output power relative to 13.8v power supplies too..Factory power supplies are designed to collapse on voltage to about 12.5 vdc or so..at rated power load...
