Cheap and nasty. Batteries would have to be identical all the time (state of charge) . If one fails, they are no longer identical. Potential for power from one battery to drain to the other. Simple diodes the solution. Each battery can only send power, can’t receive it.
That's the purpose of this. If one battery fails you still have the other. Yes, diodes work but then that defeats the purpose of doing this setup for a "simple" solution. I've run this setup many times and never had any problems.
Great video. I would like to know if this set up can be use on any Futaba Receiver? Also if there is any way or change to damage the servos or receiver itself by having two power sources at the same time. Thanks
Thankyou so much for this video. I ran the same setup, but… my servos are only rated from 4.8-6.0… my battery is 7.4… so, I ran a programmed b.e.c. At 6.0 volts in between the battery and receiver.. if I didn’t do that I would have fried my servos in flight for sure. So thanks to you mentioning this in your video it saved what would have been a failure. Thanks !🙏
Ive used different redundant systems like these: th-cam.com/video/TK8MYkRHxck/w-d-xo.htmlsi=t1jDSntBMrg-a9jJ or th-cam.com/video/yowcjweWkaQ/w-d-xo.htmlsi=YbFccqqrL_1zAk0I
When you have 2 similar packs, the current rating is the same and they balance out. Theoretically I guess if you had a battery on one side that put out a lot more amps then I suppose a little back charging may occur. But that's why we use the same batts on both sides so it's balanced. Good question 👍

This will work on Futaba and pretty much any receiver out there. You shouldn't have an issue with damaging servos or receiver.

Thanks for the comment. I'm glad it helped.

good info friend! I thought if you ran two ESCs you could plug them both in too, but apparently you cant do that?
The power would work but the mixing to make two throttle channels would be a trick. Best to remove the power wire from one of the esc plugs.
Ive done it with a jet. I did put in a schotty diode though.

Can't one battery backfeed into the other?

@@ChunkyC_RC thats good to know. Some insist it will backfeed some say it is fine so I was curious
@@AlanC5794 I've never had any problems when using identical batts.
Yes, can feed back. Need diodes to be really redundant…the whole point
That’s good shit boy! Great info, but I need a bit more Chunky C ism’s.
I'll work on that 😉
