Battery Wires

[cueman100]

Has anyone extended the wires on their battery's?
I want to extend both the hot and ground, and the balance plug wires to make them about a foot longer, for a special project. Will this hurt the performance of the battery?
Thanks

What sized heli ? and how long do you need to extend ? Generally you want to move the electronics, very rarely should you ever extend them.

[cueman100]

need to extend them about 12 inchs, 90 size nitro in a fuse.

Sounds like a really bad idea to me

If it is just a pack that is running the radio equipment I wouldn't worry about extending them. If you were extending flight packs then you could use those castle creations cap packs.

If load current is heavy, you could use a larger gauge wire to compensate for the extra length. If the wire is sized up correctly, there will be no degradation of load voltage; The only penalty is a little extra weight and the work of replacing (not just adding on to) the existing wires. The balance wires are less critical so you could just extend those with the same gauge.

You could look up wire resistance per length to figure out what larger gauge to use.

If this is to an ESC, the issue is much less about power loss and much more about inductance.

Not sure why you want to extend them. Is it to have the lipo in its "place" to stay and then charge it while in the fuse? If so there is a Deans plug that goes on the side of planks for something. I have seen adds for them, but not sure what they do. You could use one of them and wire your lipo to it. Then just plug your charge end to the side of the fuse. For the balance lead you could have the plug on the outside (fitted tight to the side) and have the wires on the other side "tied off" (so they wont pull out) and then run to the lipo. Just a thought.

There is no inductance on the battery leads in a straight run. Inductance takes a coil of wire. Resistance yes, and thats why the Cap Packs sometimes help, they can supply a momentary punch faster than the battery can.

If its for the servos in your Fuse, no worries on length, 14ga gona be plenty. If it's for a ESC( but you said 90 sized so I assume Nitro) ESC it would be wide to make a jumper of atleast the next larger size. Battery will be removed for charging I assume too?

How much ya wanna bet ?

Running long wires to an ESC is a bad idea. If you must extend them use large wire then add a capacitor bank at the ESC to compensate or risk blowing up your ESC.

There is definitely inductance on straight runs (or any run). It's just really small for the tiny runs on helis.

The OP said 90 size nitro in a fuse,therefore this is a low power rx setup ..For this application I see no problem..If it were me I would just make an extension cord ..

exactly this

I'm in a similar situation where I need to extend the wires on a BEC (Castle PRO BEC) about 8-10 inches for my Goblin 500 build.

Rather than tap the beginning of the ESC power leads near the ESC itself, I was going to extend the wires to the power connector.

Will this cause any issues? It has 16 gauge wire on the ESC and I picked up some 16 gauge stranded wire from Home Depot. It doesn't feel quite as flexible though.

Extending the wires to the BEC should not be an issue, since there is none of the high frequency step changes in current draw that an ESC causes (this is what interacts with the inductance of the wires to cause issues). 16AWG will be fine for that application, the current from battery to BEC is not high.

Extending RX pack wires is also no problem, though if it is a long extension I would use a larger gauge wire rather than extend the 2 20AWG servo leads, then split to 2-3 servo plugs near the RX.

Thanks. The CC BEC PRO peaks at 20A. I doubt the 4 servos on the G500 will pull anything near that.

20A output at 6V. Input side at 6S pack voltage is going to be a third of that current at worst.

Decided to ditch the cheap home depot 16 gauge wire.

I have some of this laying around. Should be much better and much more flexible.
