Electrical setup
 
Hi all,

I am converting my Integral from YS to El, and have some few questions ...

I am planning to use CC 5.5mm bullet connectors between the esc and batteries.
"which side" ( battery-side / esc-side) do you solder the female/male connectors ? Or do you put one male and one female on the same side ?

Any experience about this ? ( thinking about worn connectors , specially the male , by connecting/disconnecting many times . need for replacement etc).

Thanks in advance
Kjell Olav

I believe its as such for the battery side ... Black MALE ... Red FEMALE

If you plan to use bullet connectors on the battery, not what most do, make SURE to put the famale on the battery. If you put male on the battery, you will have exposed contacts that will sooner or later, probably SOONER, touch which will result in a short which will instantly destroy the battery. If the battery is a lipo, you could be creating an explosive situation. In the attached picture, you will see a more common set up. Bullets from ESC to motor and Deans from ESC to battery. Make CERTAIN to maintain polatity when making battery to ESC connection. If you use bullets all around, there is the ongoing chance of making the wrong connection. Deans takes away that chance. Good luck.

You would do it this way if you were planning on using your battery packs in series. It avoids using an additional connector. But you must be VERY CAREFUL(!!!!!!!!) you don't short your battery.
Otherwise, it is much safer to have the females on the battery and the males on the ESC. You'd need to use an additional connector to connect batteries in series, by you're much less likely to short a battery.
By the way, Deans Ultra connectors (shown above in the picture) have low resistance and are good up to 100amps. They are also what most people who fly electric use.

JMHO,

Here is my solution after burning a few holes in my old transmitter case.

Seems like a good solution Jim, i go for that one ...

By the way, i am gonna use two of your regulator ( jaccio without switch) 5,7 and 5,1 for primary and secondary battery. (800+400). I also thought i should plug the receiver power directly without any switch, since i have to remove the canopy anyway each time. Just wondering if there will be any wear on theses connectors over time ... I could also put a small extension cable between the batteries and the regulator and "sacrifice" those plugs instead of the regulator-plugs ... What do you think ?

I assume you will be using LiPos? If that is the case then I like the extension idea. You can stand some voltage drop in the connectors as opposed to five cell Nixx packs. Then you can tell us how long the connectors will last. Years ago I used a modified servo extension as a shorting plug instead of using a switch and it didn't last a season before the connectors got intermittent and I couldn't turn the system off.

Let us know if you ever see a significant drain on the secondary battery.

I only use DEANs style connectors and even for parallel or series I am more comfortable with extensions. Losing a few amps is ok, a whole battery shorting is much more difficult to explain. :)

Jim,

Both receiver packs will be Lipo.
I have also thought about replacing the JR connectors on the batteries / reg`s, to a kind of "mini-deans" . Maybe they will manage for a longer time ... They could be easily replaced also ..

I saw an article somewhere here in this forum, using two Jaccio reg w/switch, and only using one switch; controlling both reg`s !?. hmm, i have a dosen of the Jaccio reg without switch ,every type... trying to find a good solution for them :-)

If you are using redundant power sources, it is not important to have the fail safe function of the Perfect Switch Harness as it is unlikely that both would fail at the same time. So in your case the regular regulators should be fine and probably more reliable than a single battery with a single regulator. But to answer your question, yes I can build a two regulator/one switch, switch harness. Contact me at:

Thanks Jim,

You right; the reduncy is already taken care of ...
Anyway, i contact you when my next project demands a clean and proof setup.

...In the mean time, my truly Jaccio - regulators keeps working ...

Why not just use EC3 plugs...basically they are bullet connectors contained inside a plastic shell....less chance of shorting or plugging them in backwards.

Hi,

My " EL - Integral " have 20 flights now and everything work just fine so far ...

I went for the CC 5.5mm bullet connectors , and the arching - impact - point seems to be between the edge of the female and in front of the male .. Not the contact surface itself .. Nice; long lasting connectors :).

I removed the rx switches, and just plug the Jaccio reg`s directly into the batteries ( 800 lipo main , 300 lipo backup) by using micro deans ( ref picture ). Those are small and solid , good friction and thick gold-pins that also prevent misshaps :)

Thanks guys
Kjell Olav
