Those are some of the questions I would ask Joe.

Not Joe, His Dad. Winter here right now, The 58" edge doesn't even have the cooling holes open in it yet. So not able to give a temp impression. But same as the others we are running. No Failures or problems. They seem to be really well made compared to all the other brands we have in the Battery box. Holds the voltage well through the flight. Good heavy leads on them. And they came well balanced.

Heli

I fly with a bunch of Heli Pilots and we all use 6S 2650 to 5000 MAH packs. Most use Deans connectors. I have a lot of Turnigy batteries that work great but another brand would be good to try too. I find the lower C batteries are usually the ones that I have issues with. There are several other new brands out there, Spyder, Pulse, NRG, etc..that I have seen people getting lately. I have a couple of NRG's for Nitro power supply. My most problematic batteries have been 30C Thunderpower packs that have puffed.

There are a lot of heli guys I know that would switch to dependable, well made and good rated packs with higher charge rates.

May have to see some of the prices online and try out a couple of 6S 3000MAH and 5000MAH packs as well as a 3S 2200.

Is there a chance you might offer connector choices??

Thanks for the info.

Spyder is not what I would call a new brand as I tested them over two years ago.

ours came with really good Bullet connectors. But we switched em to Deans.
They seem to be really well built.
And that Haiyin actually makes the cells impressed us.

They did, but you could hardly ever find they had them in stock and I never saw anyone with them in the SE area.. Just meant they were not like the bigger manufacturers...

I've had a few Venom batteries but they tended to puff badly although I know they have some newer higher C rated ones now.

Is there a coupon code for the Haiyin site, they have a place for one? I'm thinking about getting a couple.

Been doing some actual side by side testing(actual flying testing) of the Haiyin batteries against the batteries we had been buying(same cell count, size and c rating). But there is noticeable more pull out and lasting power from the Haiyins. Noticeable even enough for spectators to visually see a difference.
Not mentioning the other brand. And yes same plane, put battery in, fly, change battery, fly.

FWIW My 20C 3S 800 mAh which I bench tested for a total of 51 cycles is now being flown in a flying wing which I have tried many different props on, some pulling over
20A static.........25C .

Current favorite prop pulls 13A turns 16K and comes down after 5 min. at 3.7 per cell. with no noticeable heating and no signs of fading. Cycle count now at 57 ,----51 bench and 6 flights.

That's what we are seeing too. No fading during the flight.

Charge Rate?

What's the maximum charge rate on these packs? I am looking at the 6S 5000 40C.

I think they are just going on the side of caution when they specify the charge rate. I wouldn't hesitate at all to charge them at 3C. Some of the other companies boast you can charge up to 5C but I would never do it. The pack might take it but it ain't gonna last long.

I charge everything I have at 2C. No harm, no foul. The only time I use 1C is if I'm trying to revive a sick pack.

BTW, the 6S 5000 40C has a published charge rate of 3C. I'm not sure why the 20, 25, and 30C packs would only be 1.5C
