Turnigy 5000 4s 65C discharge........any good?
« on: April 29, 2012, 08:27:02 PM »
Title pretty much says it. I want a good 4S 5000+ to run in my SC8. I'm trying to decide if the lower price (compared to a Reedy) means I'm buying a bomb and don't know a lot about batteries. Can anyone offer an info or help? Thanks guys

ive used the older blue turnigy packs and the new nanotechs, never had a problem, and more than happy with their lifespan/performance. i'd spend a bit more on a higher discharge pack with the 1/8 scale, and it's still cheaper than a store brand  8)

Thanks Cory! Do they make a higher discharge pack than that 65-130C 5000? That was the highest I saw.

That's as high as I have seen and is plenty.  Anything over 30C IMO is lots.

What's the difference in discharge rates? How does it affect performance? And what rate would you discharge a 5000ma 6S 35C lipo at? How do u determine the discharge rate when charging? Greatly appreciated!!

   Discharge rate is the "C" rating on the Battery. It does not have any relation to actually charging or discharging the battery with your charger. The way it was explained to me is the higher the "C" rating the more punch it has. It's how much power the battery can supply continuously, and burst. For example the battery I am looking at has a 65C rating for continuous discharge and 130C, I believe, for burst. So when you yank the trigger to haul ass it initially will pour power in then taper of to the 65C rating. Could be the difference between spinning tires and pulling the front wheels off the ground.Free moving power = less heating up of batteries,esc,wires etc. I hope that helps. I'm sure there is more I don't know and if I'm wrong someone please correct me.

Agreed. Its a beast I'm sure. I like 40C-45C and would be pretty stoked to feel how the 65C would kick Lol

Appreciate ur time to clear things a bit, just a little unclear on what to set discharge setting for.... on my charger when charging, for example a 5000ma 7.4v lipo with 40C rating....

^ You mean the charge rate.  Always charge at 1C, that is for a 5000mAh battery, charge at 50mAh.  Many chargers just ask for the mAh of the battery and set the rate automatically.

The C multiplied by the mAh gives you the current capability of the pack.  A 5000mAh/40C battery can dump 200amps.  So can a 4000mAh/50C battery or a 10000mAh/20C battery. 

Most 1/10 brushless systems won't pull over 100amps so a 5000mAh/20C or 4000mAh/25C is plenty.  Castle rates the MMMonster to 120amps so a 5000/30C or 4000/40C will cover most 1/8 systems.  Higher is always good but not mandatory

if you were storing your lipo,s for any length of time you might discharge them to..lets say 3.6 v per cell..half charge

Hi Dukk
I think you meant to say, a 5000Ma batery should be charged at 1C which would be, A 5000ma battery is a 5Amp battery and should be charged at 1C which would be 5Amps not 50mAh.

IMO, turnigy nanotechs are pretty meh for what they're rated at.

I ran two nanotechs in a heli I had and just after five minutes of running, they were warmer than I was comfortable with and put out less power than what I was expecting.  That alone told me that the nanotechs were overrated for what they can provide.

The blue turnigys i've seen run extremely well.

Can't say I agree with this. All of my Nano techs have been the best performing batteries for the price I've seen anywhere.

I was pulling 850 watts from their 3S 2200 65 packs and it landed stone cold after 12 minutes. Did a 1500+ watt torture test in a buddies boat and they still stayed above 11.1 volts loaded. Was hard to believe just how much they lit up a boat that was used to seeing 35C packs. Pretty much doubled the performance.

Maybe you ended up with a bad batch.

I may be wrong here, however, I believe as a lipo ages, its C rating decreases.  Meaning, a 25C 4000mah battery would be capable of punching out 100amps.  However, as the battery ages, its current output capablity slowly drops, and at some point, it will no longer be able to provide the amps required by the ESC, and thus, that is why they puff up.

So, by buying a higher C rating than you need, it will lend to a longer life span on your batts.  Just my two cents worth.  ;D
Reality is anything you believe.
Nevermind testing the water, just jump in and enjoy the thrill!
If you know you're insane - you're not!  It's the REAL crazies that don't know.
Just be yourself.  Cuz if you're not, you're acting like someone else.

more is always better, and ive got a couple new nano's and they are great, had a bunch of old blue ones too, no plroblems. And even with shipping/customs, it still works out to the fact that you can buy 2x the batts for lhs prices, and a higher C.
