Rookie electricity question

[Bucketface]

Hi

My question is pretty basic, I haven't got the means to test these configurations right now but I'm looking to do a new board and wanted to iron out these things first. Basically I'm looking at keeping costs low as I already have some parts from my first electric board build, I already have one 6s ESC, to supplement that with another 6s ESC would be much cheaper than buying a dual 12s ESC.

The question:

If I run two motors, two escs, and two batteries, how do they work in different combinations e.g. one 6s lipo connected to both ESCs and the motors versus one 6s lipo connected to each ESC and the motor.

My guess is that with one 6s lipo connect to both ESCs the motors would be slower in comparison to having a 6s connected to each ESC.

Is having two separate 6s battery banks connected to each ESC independently and two motors the same as having a 12s ESC connected to a single 12s battery bank and two motors?

Hi,

Common sense would induce that you can just divide the voltage between motors so 12s divided between 2 motors would mean 6s but oddly that's not the case.

When you feed your system with 12s level of voltage you end up with this level everywhere . Plus 6s will not do your motors any good unless you do flat ground ride and your motors are sized for it.

I'm not sure how you want to successfully achieve a 12s ESC with 6s rated components, can you tell us more ?

We'll if you have (1) 6S LiPo to both ESCs it's the same as (2) 6S LiPo's to each ESC.

IMO There's no point in separating them IMO it's pretty much the same but definetly much more efficient wiring both batteries in either parallel or series.

A dual 12S is 44.4v to your motors so it wouldn't be the same as a dual 6S 22.2v to your motors.

12S 44.4v to both motors is the best.

Thanks those are both helpful answers. That makes perfect sense. I wasn't aiming to achieve 12s with 6s I was just using it as an example.
