actually i believe a full scale aircraft battery would be on the leading edge of battery technology. they are deep cycled periodically. this prevent the battery from developing a memory. memory is when you use the battery more than usual. you wont get a rapid discharge to an unuseable voltage.
however you dont need a cycler to perform this function. i dont have one and i cycle my batteries every couple of months.
besides TX batteries are diode protected you have to remove them to use a cycler on them with the correct battery connector.
hope this helps put out the fire
