I was wondering when to charge my Tx and Rx batteries. I have a Futaba 4VF setup (sanyo nicad batteries) and I have a 4.8V 600mah for the Rx and a 9.6V 600mah for the Tx. At what voltage reading should I recharge them (my voltmeter has dummy load)?

I am using the provided wall unit until I get a cycler, it has 50ma output for both Tx and Rx. The batteries say right on the pack to charge at 60ma for 15 hours, but is this from a completely discharged state? (I need some voltage numbers).

I have been just leaving my Tx AND Rx on while I use FMS simulator and when they (the Tx first) croak (i.e. needle on Tx is at or below 10%) and FMS and servos are not reponding I then recharge for 12-14 hours. Is this a bad procedure?

Also, I have a 12v 7.2ma lead acid battery, at what voltage reading should I recharge It? My charger is 600ma.

Thanks for any and all info,
Cheers!
