4.8 vs. 6.0v battery

Hi Guys or people i should say! While reading the most recent Tower Talk, it gives 2 ratings for servo voltage.(4.8&6.0volts) Does this mean i can take my 4.8v reciever pack and add one more cell to get more torque and speed out of my servos? :

Yes, thats correct. I use both (abotu half and half) 4 and 5 cell packs. % cells with give faster responce and higher torque, but the drain will be higher also. So a 600Mah 4 cell pack on the same plane will last longer than a 5 cell. Just make sure you remember to charge the pack on the 5 cell setting, and vis versa. It sucks to charge a 4 cell on the 5 cell setting as you will overheat and damage it. Been there done that!

Some radio gear doent like 5 cells, however, (some JR servos and some gyros) so be sure to check with the manufacturer specs before you go for the extra cell.

Thanks for the reply Andrew. Had not put enough thought into this. Forgot about charging 4vs5 cell pack. Thanks again.

4.8v - 6v

I've been flying giant scale for about 15 yrs and have always used 6 volt for them. Accually started back when flying 60 - 90 size. I notice a differance with 6V in responce time and its always nice to have a little more torque. I usually run 1700 ma pack and with gaint servos or higher power regular size I'm still good to fly most of the day unless out at fun-flys, where I sometimes quick charge things when I go for lunch. Now a couple of my bigger planes - where I have a fair amount of money into them I'm putting in two receivers, two switches and two batterys, one running each side of plane. I figure theres a little bit of redundancy for a $150 cost. Last spring had a battery cell crap out in a 2 mth old pack. Didn't notice anything wrong until I landed and noticed one side moving real slow. With only one of, I don't know if I'd have made it down in one peace.

I have used both 4 cell and 5 cell airborne packs. There are postive and negative things to each setup. Do you need more torque/transit speed or do you want longer battery life with less wear and tear on equipment?
I am sticking to 4 cell this year ...one reason is that I think it is much easier to take care of the batt packs.
