Yes. They are preferred by many of us for their durability and safety. Personally, I won't put lipo's in a gas plane, although many do.

My Promodeler servos are capable of 7.4V but they work fine in the 6.6-7.2 volt operating range of A123's. Just because a servo can handle higher voltage does not prelude it working with less voltage. My other legacy Hitec servos are non-HV and they work just perfectly with A123's as well, since A123 voltage is no higher than that of a 6V, 5 cell old-school battery pack.

Agreed. Other features are a consistent 6.6v and long life- many cycles. I personally know multiple people who have had fires in their house, in addition to stories I read online, from LiPo fires. While I do have some, I am consciously trying to rid myself of them and those that I have I store with extreme care.

I've been using A123 batteries exclusively over the last 10+ years. I refuse to put lipos on my planes with only one exception - a giant warbird with Robart electric retracts that needed more voltage than 6.6 to work properly/ consistently.



Lipos go only in a few EDF jets I have and then I am extremely careful when charging, discharging and using them. I never have to worry about my A-123's. You can't beat peace of mind and simplicity.

.......What THEY said! .......

Same for me. 10+ yrs of excelent performance by these cells/packs.

You know I been a a123 fan sense we robbed them from Dewalt packs.But I just bought a plane that has two Booma RC 3600 Smart Li On's in it.I got to say I am impressed the way they hold a charge and the number of flights you can get.I know nothing about these batteries,I suppose they have the same risk of fire?

I will add my vote for the A123's. I leave them in my plane all the time, including while charging, and I leave my plane unattended in the shop while charging. Like everyone else, I use LiPos for the power packs in my electric planes but those batteries get very different handling.

Another vote for 123's and LiFe in general for my gas and glow planes

And another vote for me as well!

A123 ALL the way for me.
