Does anyone in stunt land have any experience with the new Generation Six (G6), 65C batteries?  600 cycle life expectancy and 12C charge rate sounds kind of exciting.

Norm Whittle

would be good to be able to fly off 2 packs a day tho - 12C charge rate - you could be "fueled up" again in around 5-10 minutes!!!!!  - that is of course if you could find a charger to provide that sort of output.........

Thanks guys
Well it is true the G6 pack weighs more.  I presently use the G4 5S2600 20C Thunderpower batteries, with connector they weigh 10.5 oz. the G6 5S2700 65C weigh 12.85 oz w/connector for a delta of 2.35 oz.  On a 60oz stunter the weight of the battery would need to be shift 1.1875” rearward to maintain the same CG vs. the lighter 2600mah battery.   The G6 battery is 5” long vs. 4.5” for the G4 this could complicate moving the battery rearward.  I originally flew my Sultan-e with 5S3300mah batteries at 13.8 oz for the battery with no detrimental effect on the performance of the airplane.  With the G4 battery the airplane weighs 60 oz with the G6 weight increases to 62.35 oz.  I think I can live with this flying weight.
 Price wise the two generations are close at $105 for the G4 5S 2600 and the G6 5S2700 = $117 (I paid $115).
I did consider following Igor’s lead and I bought some A123 cells.  I even contacted Igor about getting an AXI 2826/13 motor (optimized for 6 cell A123 batteries) Igor was ready to send when it hit me 15.5oz for batteries is kind of heavy.  By the way, if you buy a DeWalt 28VDC battery pack at $69 you get 8 A123 cells cheap.
I presently charge my 2600mah pack in 45 min at a 1C charge rate.  If I set the FMA Cellpro 10S to 3C (8.1a) charge rate, I can charge 2 batteries in 15-20 min.  Ain’t technology great?  We do need to keep Afghanistan under American control; after all the majority of the earth’s Lithium is there.

Update:  ThunderPower power is now shipping G6 45C batteries.  Less weight and cost that the above - man it’s a great time to be flying electric.

Igor's model at the 2008 world champs used a 6-cell A123 pack and he was charging it at 10 amps with his FMA charger. An 18 minute charge was all he needed, and he only used 1 pack. He still does! Igor can correct me, but I think that he had over 600 flights out of the pack. The new lithium technologies are getting better by the day, and a 5C charge rate is already there with many Lipos like the TP and Hyperion batteries. Exciting stuff!

Sorry Keith, I missed your post before ... Yes I charge it 10A, the most imprtent is, that the CV phase is very short, so the charging is timewise very eefective. I did 400 flights on one battery and then next year another 200 but I needed shorten flight time by 10seconds 

Now I test new Lipos with 5 to 8 C charging (officialy allowed on pack). I also charge it by 10A, but the CV phase is very long, so I cut it at 1A, may be even earlier, so the charging time is the same, but I cannot use full capacity. I do not like to exchange batteries, because of trimming (diferent position, may be also weight), because of internal resistance etc. I just want all the same every flight.

Peter, the problem, is, that if you change that charging current from 4A to 8A, you save only few minutes.. I think no more than 10, but A 123 will take really only half, becayse CV phase does not take more than 1 minute.

And regarding weight - yes the weight is with only small differencec, but if you cahnge battery, and if you move few milimters to the side, it will retrim the model. Well trimmed model can feel tip weight difference 0,5 to 1g, and if you move 350g only little bit, you will feel it. So my solution is not to change it 

Thank norm for the clarification.  I will report back on how the G6 Pro Lites are working for me.

RCLipos or from Thunder Power directly.

Crist,
Is there any weight advantage to the G6 Pro Lites series over the G4' Pro Lites?

Best,          DennisT

Not according to the charts on the website.  Both were/are listed at 292 grams.  Again my battery weighted 298 grams.
