spark suppresser

Any on know where i can buy a spark suppresser that plugs into the receiver

?? For brushed or BL?

I think Spektrum has something similar to that, but i have used this one on my cars and it really works.

im trying to elimate spark when using 2 3s lipos when pluging them in?

[tlandauer]

Those don't go into your receiver, that's why I was wondering what exactly you meant..

thank you now i am using the traxxas connectors on the batteries so i will figure out how to adapt these

I am not home, so i can't look it up for you. But you can make this yourself, I did it once, inside the loop is a small resistor. You plug in the small resistor and then the main loop, then disconnect the small wire. I have not used them and my memory is a bit foggy at the moment.

thanks for the info and merry christmas

I built mine following this diagram:https://forums.offshoreelectrics.com/...chmentid=86404
Cheers and Merry Christmas to you!

You don't need a permanent suppressor. Just add your choice of connector (I used small alligator clips) to each end of the resistor and shrink tubing ... this way you can use it on any boat. Connect for a few seconds to charge the caps and remove and connect as normal.

sorry for the stupid question, how do you know what resistor size to get. thanks

My link , #8 post, once you open it, there is a detailed instruction.

I must be missing something it states resistors from 20 to 50 but how do I find out how much do i need for the voltage

I assumed it did say. I went to Radio Shack or an electronic supply store, this was 3 years ago, so don't exactly remember. It did say from 20-50ohms, so depending your set up, should be able to find the applicable ones, I don't want to steer this the wrong way, surely someone will point us at the right direction.

That's the thing, I haven't decided on my setup for my Twin 37 C.F. Shocker 4, 5, or 6 cells with 2700kv 2200kv or 1800kv . All I have now is the esc Seaking 180 v2 with extra caps and the Shocker.

I've never used them, but from reading the linked thread, use Ohm's Law to work out the resistor value.

R = V / I

It looks like the goal is between 1 and 2 amps on spark eliminator circuit.

The size of the resistor determines the charge time. To small and it charges to fast and you still get a spark. To big and it takes to long to charge. Here is a link that has a calculator. 2 to 4 seconds is a good range.

something to consider...... Ive run up to 8s without one, but i'm using a connector that plugs in both positive and negative at the same time. Ive noticed if you plug them in seperately, you get a nice spark...plug in at the same time, it doesnt do it. I run some pretty stout caps too.

Thanks guys, I appreciate you all for taking the time to help me out. There's so much to learn and i know so little.

Now that's interesting. Unfortunately with our safety loops here in Oz it's a one wire connection. I guess a twin loop could be configured.
But I just use these as the loop connections.

I also use these.

Question, when running 6s2p, do I still only need 1 spark arrestor? In other works, can I build my parallel wires to be configured with 1 arrestor? Connect the negative sides of the (2) 6s packs to the parallel harness and then to the esc, then connect the positive sides of the (2) 6s packs to the parellel harness. Then make the final connection with the smaller connector on the spark arrestor and the final main positive connection on the ESC?

[785boats]

Yep.
That would be the way to do it.
