Hi Guys thread looks good. From the uk and keen to share anything learnt about the f550. Having some trouble with batteries at the mo.

I have an f550 + naza v2 standard arf kit. I'm looking to increase flight time (as usual) but having changed from a single power buzz lipo 5000mah 4s to dual 3s 3300mah the motors will only operate if one is plugged in not both (it's a simple deans dual connector for both). When set up with dual batts one or two motors fail to start up and motor testing does not work properly.

I haven't recalibrated the flight controller in assistant but I didn't think that was necessary as I have changed the voltage settings etc and the batteries are giving out regular readings volts wise.

As is probably obvious i'm not a battery wizard so any advice is hugely welcome. I'm pretty sure the voltage level is ok. limits are 26v 6s.

if anyone has done something similar I would love to her about it

You wired something wrong..  That isn't possible unless 1 battery is dead and taking all the power from the other..  That or you wired it wrong are the only explanations

Yep, I agree with Mark.
