Can anyone confirm operation from 2S? and how low can a 2S battery go and still get 5V out? The similar X3 needs 9v to deliver rated output. Mike

Tested yesterday. It supplies 5.5 V with a 3S 2200 Lipo input. It is enough for 4 digit servos supply in a 3D plane! I hope the current will be good as well as the voltage.

Hi Jetson. I use the previose version in loads of my planes and heli's. Far as I am concerned its bullit proof. Not one issue ever. Use it with confidence. Happy Landings

Would it be a good move to solder 3.5mm bullet connectors and plug this in to the power distribution board?

The best practise is to connect all power connections at one point (star type as opposite to tree type wiring). So connecting to power distribution board is a good place.. Other thought. This bec is low current .. so you do not need 3.5mm bullets which is ok up to 30-40A ... you may smaller ones like 2mm to save weight.

Whats the difference between the two UBEC's (this one and HKU5) besides the name? Thanks
 Finnius 234 points
The X5 (X5UBEC) looks identical, any difference?

This one is wrapped into metallised tape under heatshrink to reduce switching bec noise
 Finnius 234 points
Thanks. So the tape reduces noise from this device, to minimize interference with other devices?

exactly..

I connect the input of ubec and output of battery in a wrong way... which mean red connected to black and black connected to red. Suddenly, it sparked and now it is broken. It doesn't work at all. It's better than exploding :D

Purchased three of these for ignition voltage regulator duty in my large scale gas planes, when paired up with the turnigy 2100 Lipo receiver pack, you can run an engine all day versus the 4 cell NiMH packs. Working great in my planes, the 3A version works great too, but is a little longer and slightly heavier, but cost less. Next order, I will order more for spares for future projects.
