Battery for f450

[Prehn]

I have just build a f450 with naza v2 gps

And had my first flight today.
Waited till green flashing and tool off. All looked good. But 30 seconds in flight red led started flashing. I took it down and looked ind the manual, "low battery Warming"?
Wierd, as i was sure the pack was fully charged. New pack in, and same thing happend.

Im jusing this battery

Is that to small?

Is a bit small but should at least run for 6minutes or so. What voltage was it when you started/finished? Also in the naza assistant you can set the voltage warning level. I always lowered mine to 10.2V

Why not get a LiPo battery packs with bigger capacity? 2200mah was too small.

This one 3S LiPo battery 5200mAh. http://www.wtotoy.com/ge-power-11.1v-5200mah-30c-li-poly-battery-pack-for-rc-helicopter.html

Then you can have a longer flight.

Can it lift such a huge pack?

Does the phantom 1 not come With 2200mha?

I use 4s 5000mah in my stock f450 and it flies brilliantly with 15+ min flight times

Wow. Thats impressive. Iv got 4's 5000 batterys for my buggy, and they are heavy.

But now i tryed to lower cutoff to max. It Will not go lover than 9,9.
When i recharged my packs before they where at 4,0v pr cell.

Will se tomorrow what it does.

You can also charge your packs to 4.2v per cell..

Yes. When i start out they are 4.2. And when it flash red they are at 4.0.
But yesterday it was raining, so i did not test the new cutoff setting.

Can you post a screenshot of your battery config page in DJI Assistant? Sounds like you are configured for a 4S pack, instead of the 3S you are flying.

 

[Prehn]

Will do. But it says 3s

Finally succes.
Today i got three packs in to it with over 5 min of flying.
The lipo cutoff is now set to 9,9v for my 3s batteries. It is as low as it gets for the software. I Think it is Strange, as i normaly set cutoff to 3,2 Per cell. Sometimes lower in my racecars.
But it worked and im happy.

Thanks for the help in this thread.
