Friends :) planning to buy rechargable batteries( (:|~) for flysky 6ch transmitter.. please suggest me which one to go for ??? ??? ???
normal nimh 1.2v cells
life 9.9v battery
or 3s lipo 11.1v
and also can i charge the nimh cells using the transmitter itself through the adapter port..?
which adapter to use then..? :headscratch:
thanks in advance..  :hatsoff: :hatsoff:

arun, here is an earlier post hinting a similar situation.

http://www.rcindia.org/batteries-and-chargers/battery-for-flysky-th9x-(suggestions)/msg106925/#msg106925

I believe the FlySky 6 also runs the same voltage configuration so this should apply equally well.

Yes you can charge it via the adapter port, but if you plan to use a LiPo or a LiFe, you should be getting a much more dynamic charger which is capable of charging and balancing these special batteries as the stock adapter port will not allow you to balance charge. I use an accucell 6 to charge the battery. And i am running on the LiFe from HK - 1500mAh

thanks girish.. i already own a lipo charger but i was about to use nimh batteries in it thats why asked about the charger port.. can i use 12v 2amp adapter for charging nimh..

12v 2A sounds okay, but care should be taken not to overcharge and the charger needs to cut off, typically time would be about 10-12 hours but depends on the current flowing in the circuit, which is dependent on the state of the cells. Additionally, NiMH is good to charge at c/10. Charging in the transmitter would mean charging all 8 in series, due to slight differences in the capacity of cells, the best case is to charge each cell independently or in smaller batches so an inexpensive charge that charges 2 or 4 at a time might increase the overall battery life.

I'd still recommend going in for a LiFe, for two primary reasons:

1. LiFe is 9.9v and NiMH (8 * 1.2v = 9.6 v), your transmitter will have atleast 0.3 v before it starts beeping about low battery
2. LiFe hold charge better and will provide longer runtimes.

as a test run, when you connect the charging circuit and leave it for about 5 mins, if the NiMH heats up, the current running is high enough and will reduce battery life/ damage. keep a watch while charging

so :) i dont want to make any complications and as you suggested i am going for a life 9.9v...
thanks for your help man..   :thumbsup: :thumbsup: :thumbsup: :thumbsup: :thumbsup: :thumbsup:

but the life lipo from hobbysea has a dimension 102mm x 23mm x 28mm
will it fit inside the flysky 6ch ??? ???
while measuring the thickness of transmitter battery port it is smaller than 23mm..  >:( >:( >:(
what to do?  :o :o

girishsarwal

how many NiMH cells do you typically put into this radio, 4 or 8?

girishsarwal

nothing, dont worry, i was just browsing the tx section on HK and wanted to confirm that yours is running on 12 v, there are some on HK which seem to look similar but run on 6 v

arun.sreelakam

girish i agreed that life will suit my transmitter but the dimensions are my problem... when i remove the batteries from the transmitter and measured.. the thickness of battery should be 18mm or low.. >:( >:( but hobbysea life lipo shous 23mm :(
is there any life battery suitable for me available..? :banghead: or do i want to make any modifications in transmitter? :banghead: :banghead:

I use LiFe 1500mAh from hobbyking for my turnigy 9x.
This LiFe suits only those which have a 4cell+4cell arrangement, not an 8-cell flat.

 >:(so which one should i go for.. mine is an 8cell flat arrangement..  :banghead: :banghead: :banghead:

Oh yes, I remember seeing that Tx LiPo being used.
But measure your compartment and see if it's considerably bigger than the LiPo itself.

thanks swiz ... yeah it will be perfect.. should i get these lipo from any indian sites.. hobbyking want to wait a lot of time..  :( :(
thanks all i was about to order the life lipo which will become useless if i had orderd... >:D >:D

@hyd_quads: yeah actually the dimension is smaller and swiz suggested me a lipo which will be perfect for me.. :)
thanks friends...  :thumbsup: :thumbsup:

880 + 80 (their shipping price AFAIK) is not a very decent price, but it's okay, you can go for it. :)

The ebay item you gave is located in China. If you want it, it's as good (or as bad) as buying from hobbyking.

But I think you can go for thehobbyshop.in item.

finally decided to for for hobbyshop item...  thanks friends...  vineet,swiz,girish   :salute: :salute: :salute:

Your radio doesn't have a female connector, so you need to solder. I had soldered my Tx LiPo when I was using the same Tx.
You can solder from outside and the LiPo fits in the compartment.
