Is there a way to power a stationary aircraft without using the LIPO (For testing on a bench?)

[Ducky84]

So I'm tweaking some settings on my transmitter and aircraft. Things like servo adjustments, or testing accessories, and I don't want to bust out the LIPO's from their fireproof case every time I do this. Is there a way to power your aircraft some other way where the aircraft is stationary?

When I setup my models I use an old receiver pack from one of my gassers. Its a four cell nimh at 4.2v that you plug directly into your rx. On benefit to doing this is that you cant accidently start the motor because its not powered. You could also accomplish the same thing with AAs. Anyways, hope this helps!

here's a link to one of the rx packs I was talking about,

I always use a powersupply with adjustable voltage and current limit, this also prevents any chance for magic smoke.

I use a wall wart, those 5V power supplies we all have laying around. Just cut off the end and solder on a servo connector. Make sure to get the polarity correct. No batteries to run down, just plug it in and go.

I bought something a long time ago and can't remember what it was, but it actually came with a 5v wall wart with a servo connector on the cable.
I've also rigged up a high current 12V wart through a BEC when I want to exercise servos a little more vigorously.

I use old 18650s from a laptop pack and have some basic battery holders from banggood wired in 1s, 2s and 3s depending on my need

Remember if you are only testing the rx or servos you don't need more than a 2s regardless of what the plane normally uses.
I have an old 1800 2s that sits on my bench and has done so quite happily for 3 years (it is charged about once a year) so it is always available for testing.
Reckless? Its all a matter of judging the risk.
Do you keep several LiPo together "in their fireproof case"? If so should you lose one you will likely lose the lot and have to trust the case is sufficiently fireproof to withstand it.

I used to use four AA batteries in a four pack series battery holder with a male jst plug for both servo and rx setup, but have since moved into a current limited power supply I built with inexpensive parts.
