like the title says, im looking at powering an emaxx with two batteries into a single esc. anybody got pics ? from what ive read so far the esc red and black are split into two male deans. red to red, black to black. whats getting at me is on the deans the red and black are gonna be hooked together. will this not cause a short ? TIA

one pic i found.

Here ya go

oh yeh. the pic you got there looks to be wiring the batterys in series. That will double the Voltage. Not sure if thats what you are looking for but heres a pic of a parallel connection. It keeps the same voltage and doubles the MAH

Jkelley · 07-30-2009, 06:07 PM

Doing it that away will keep the same voltage but will increase the Mah.
Meaning
7.4v 3800mah
+
7.4v 3800mah
=
7.4v 7600mah

It will also drain the batterys at a even rate. When you get done running your R/C and you put the battery's on charge i'd be willing to bet that both will charge up just about the exact same mah. I also run a e Maxx but I run two CC Sidewinder 4600kv brushless systems. 2 motors, 2 escs and 2 batterys. I've also got a adapter that keeps them draining at the same amount.

These are mine from my website.
will that work for ya?

JOOTZ · 07-30-2009, 08:40 PM

great info guys. didnt know one could use a twin sidewinder 4600kv on the e-maxx, i got an extra sidewinder 46kv in the toolbox- wow. where does one get a splitter for the esc plugs to the RX ? TIA

Now I will tell you this and it important that you understand this. Running two ESC's at the same time is fine but It almost impossible for both motors to run in sync. also if one of the ESC's take a pop, youll ruin two whole systems. this was basically a design for the use of 2 EVX systems.

Jkelley · 07-30-2009, 09:07 PM

Team3six is absolutely right. It takes time and sometime lots of it to get these things running in sync. That's the only reason i chose a CC systems. You can manipulate just about all aspects of it from timing to delayed start using castle link. It helps alot when trying to get 2 seperate units to work in sequence. You also will want to make sure and program the esc's TOGETHER. some people say to do them seperate. I've personally have had no luck with that method. I just turn them on at the same time and set them up at the same time.

thanks, all this tech gonna come in handy to get my rig powered up correctly

team3six · 07-30-2009, 09:16 PM

If you want more, I have this on my website for anyone that wants the knowledge. I try and give back anything I learn over the years.
Hope it helps ya. and if you need help, dont hesitate to ask.

Very nice digrams 3six, I have bookmarked to post for people.

team3six · 07-31-2009, 12:22 PM

Thanks I cleaned up the electronics pages and made them better to read and follow. I think its a bit more easy on the eyes now.

JOOTZ · 08-02-2009, 07:43 AM

way better, and very good info
