Who using A123 batteries?

[pepatrick]

I just switched my 50cc planes to A123...Today is my 2nd day at the field with them...I got 4 flights...and only used a total 800 mah..Extreme Flight 88" Yak...5955s everywhere including throttle. Decided to show off and recharged at the field...9 minutes at 10 amps..using TP-1010c charger. Now that is impressive.

Did you charge thru a standard connector ?

[pepatrick]

I will do 5 amps through the regular charge jack...but through deans..10 amps

Are you balancing as well with the TP 1010? Thanks!!!

Thats what Id like to know too. The new Cellpro charger can be used at 10A. The current 4A charger needs the 2s pack to be wired with a 3 pole lead for charging. Cant do that with a Deans AFIK so Im guessing they will need to change the setup in their new one.

Im not sure how to balance them with the 1010. The A123racing batteries have a deans connector and a single pig tail. I have the TP balancer but not sure which one to plug into..From what I have been told though...these things really balance quite well and dont have the out of balance problems li-io and li-po batteries have.

Don't think so but I've got a question about that posted elsewhere on the forums.

The reason is that the Triton doesn't have an A123 mode and these batteries have a lower nominal voltage than either the Li-Ion's or the Li-Po's.

You run the A123's to 3.6 volts per cell where the other two run to 4.2 volts per cell. So if you select the 11.1 volt 3 cell Li-Po setting on the Triton, it charges the packs to about 12.6 volts or so. I've not tried setting the Triton to the 7.4 volt setting for 2 cell Li-Po's, but if it's gonna charge to 4.2 per cell or 8.4 for the pack, that'll cook the A123's...

zeeb, you are correct on the triton info, it was designed before life's hit the hobby scene
the triton displays the "nominal" voltage of the packs you want to charge, which is 3.7v/cell for lipo, 3.6v/cell for li-ion, full charged volts per cell are 4.2 and 4.a per cell respectfully, a123's nominal voltage is 3.3v/cell and are fully charged at 3.6v/cell
there are many other chargers that support life's with more coming each day, the new triton zx will probably have life charge capability

I'm going to use A123 packs on all my large planes now. Probably go with one 2300 maH pack in the 50cc planes and two 2300 maH packs in 100cc and up.

Does anyone know if there is an advantage of the packs from Tanic vs. the ones on the A123racing.com website? Probably going with the ones on A123racing.com for now since they have a charger just for them unless the Cellpro is a better charger. Anyone know that one?

I had Brian from tanic make mine up one lead with deans and one lead w/Jr connector to go to external jack on plane for balance charger. Tanic packs are made w/ the same a123 cells. Brian will make them up any way you want. As far as chargers the a123 charger and the cellpro are about the same price. I went with the cellpro because i can use it for lions and lipos as well. Plus the cell pro will tell you how much you put in the bat. so you now how many mah your using per flight. Think of it as a fuel gage. The a123 charger charges at a higher amp than the cellpro 10 verses 4 amps i believe

Tanic will make custom packs for you as well as WildHare and Sin City Jets. I would get them from one of those places as they know what you need for your plane. I wouldnt get th A123 charger simply because it doesn't show how m any mahs your putting back into the packs. Ive been using the Cellpro 4S and like it.

[ben_beyer]

Cellpro it is then. I've heard they were good chargers, but never used one. I also like with the Tanic packs that you can get the cells side-by-side or in a line. That way you taylor them to how you need them.
