How do I know if I am getting the 20 or 25C (4900) pack?

I read in another thread that all the trakpowers are actually 25c rated. The batterys seemed to handle the added current well, so they changed the rating. You know there gonna sell more packs just by changing that little number everyone is so concerned with. I have no idea here, but is there any esc/motor that can pull 100 amps from a battery?

I was told that by a rep for them that for a year now the 20C cells hadn't been used in the packs, they just now up'd the ratings. Take that for what its worth.
One thing you could do though is see if any place will give you a discount on the 20C cells since the new 25Cs are out. I know I wouldn't mind a deal for the 20C pack.

How are these holding up? I know the Orions are good for more cycles than i will ever need but i have heard some of the other lipo cells could start seeing a dcline in performance after as little as 30 cycles. for someone who only has one that could be a matter of only a couple of months. I am curios about Trakpower and the new saddle and i would think they use the same cells. Does anyone know who the manuf is?

So what does the website mean in reference to cycles? It says 50 cycles next to 1c/16c when you click on the pdf.

Orions got platinum, Trakpowers got gold. Go figure.

Charge at 1C, Discharge at 16C (until 6.0V) and the batteries capacity will be reduced to about 70% after 50 cycles.
Sounds bad, but its really not. You car (atleast I hope) doesnt consume 85A of constant current while its on the track. From my experience so far with Trakpower 4900's a 5min main will use about 2200 mah with a 27T TC.
So, you are discharging the pack in the 5-8C range, and only 1/2 discharging the pack. LiPo's do not like to be fully discharged.
You should expect 100-200 race worthy cycles on each pack. Alot better then modern NiMh.
