I use a couple of Electrifly 8.4V - 3000mah NiMh batteries to run my Electristar. My questions is about the voltages I am seeing.
The last time I flew, I made sure I ran the plane until the engine cut off. Is this considered to be the point the battery is roughly 'fully' discharged? I measured the voltage out of both batteries and (I am going from memory here) I think they were approximately 8.5 volts. I have also read the voltage on the batteries after what I think is the proper charging time (36 minutes, charging at 5 amps on a basic Hobbico 900 timed charger). I think the reading was around 9.8 volts.
Do these numbers sound feasible? I am concerned about two issues...that I am running the battery down sufficiently enough between charges, and that, when charged, I am not exceeding some max voltage requirement. Until I can get a proper charger, I want to make the best use of the one I have and NOT damage my batteries.
Thanks gang...I am trying to learn this 'magical' battery stuff, but sometimes I get lost in all the info from the many posts and links to battery basics websites!
