Dual esc's
 
Can I hook up 2 escs of the SAME kind using a y splitter so that I can use 14.4v of power? (They each are onl capable 3s, but if I were to use a y splitter would they then be able to handle 6s?) If so how would I do it with the batteries and motor wires be connected to the ESC'S?

no it doesnt work like that.

Ok thanks. Can any esc that can handle 3s handle 14.4v of regular nimh batteries? (Cause I know that the VXL3S can handle 14.4v of power.)

the castle sidewinder is rated to 3s lipo or 12cell nimh/nicd so it can handle the 14.4v

I know that sidewinder can handle it, but I wanna know if any esc that's rated a 3s can hzndle 14.4v of power, I'm assuming they can as the sidewinder can.

It's too hard to put a blanket statement over every esc like that, but most will. You may have to run an external BEC or change a capacitor or 2, but they should.

Yeah I know it is. Ok thanks. If it can handle 14.4v of power it should be fine to use it with a 4s lipo as long as I use a external 4s lipo cutoff right?

I honestly cannot speak for the VXL stuff. I think you are tempting fate though, remember that a fully charged 4s is is over 16V, around 16.8-17.2v. I know the cells on my good packs are usually around 4.3V ea when fully charged. But let us know how it works out! ;-)

WOW! That I didn't know that about the 4s lipo! I'm not using a VXL. I 'm getting Hobbyking esc (2-3) that is just incase I burn up one of them and I need one for another rig that I have.
Thanks for the help

All lipo's are that way, not just 4s packs, the cells hold higher voltages, the cut-off is 3 to 3.2V depending on manufacture specs.

As for EsC's even our FXR's only come with 16v capacitor in stock trim, so if running a 4s pack, we recommend replacing the stock capacitor with a 25v capacitor, to cover the higher voltage.
