Jim,

Assuming of course that your system requirements can handle the 6.6v nominal that these cells provide.   Testing indicates that there is very little voltage drop under load with these cells in reference to the type of load we would be putting them under.

Fast charge rate
Flat discharge rate
Low voltage drop
Light weight
Safe to charge in plane or vehicle
Readily available through local market outlets
Easy to setup... with a little wiring/soldering know-how
Chargers available

Hmmmm... did I miss something?  Seems to me that we have a battery that everyone has been looking for for some time.

My concern is how well they handle vibration and high temperatures.

  I'm thinking to go this route as well on my gas planes, then maybe to the pattern planes.  The FG threads indicate that you do not need voltage regulators with these A123 cells.



  Thanks,

  I am liking what I see with the use of the A123's. The ability to fast charge is great.  You wouldn't have to run as big of battery.  Just quick charge at the field. Plus these batteries have such a flat discharge rate and high load capacity. What I found a little interesting about what Bob was doing is the single battery setup on his gassers.  He is running the ignition and receiver with one of these A123 batteries.  Normally a No-No running receiver and ignition on same power source.  Obviously the specktum receiver has the ability to see through any ignition noise.

    Thanks, I will digest the info. I bet all the manufacturers have gone to the 123s ? 

    What has me puzzled though is that all of the units, I think, were advertised showing 18.5 nominal volts.                              Nat

      Nat,



      Check out this link.  I think you will find everything your looking for on Bob's link.

        A recent Lowe's Building flyer was advertising four brands of 18.5v hand drills. One specified lipoly ( or lion ), the other three just said charge in one hour. Are we missing something ?  Nat
