Twin motors, 4 Batteries all 6S, require 12S to both ESC's

[[email protected]]

OK, how do you guys do it?
Wire two sets of 12S together in parallel, then out to BOTH motors? (Both motors are drawing on the same batteries)
or
Wire two sets of 12S and give each motor their own pair?

Thx

Let me rephrase.
Do I wire a battery to each motor or wire both motors together to one big battery?
It would save having 4 batteries on board vs 2 bigger batteries in series. (to get 12S)

If you can parallel batteries, then to the ESCs and out to motors you will get the system sync’d up better. I have done this by soldering in an additional wire from +to+ and another from - to - on the bullets on ESC side. I can get a pic if you like.

This is how I do my 8s twin mono:

I do the same on my big 6s cat but with 4-6s packs.
I really should shorten the leads on the pictures packs. Mmm, Sunday project!

I have done this on one of my boats, but on my other, i was told to run them separately ..?..

Lots just keep it on separate sides for simplicity. I have my SAW cat like that and my HPR twin as well. This winter my SAW cat gets a freshen up and I will join the ESC’s. On the mono I have pictured this was the only way that I could get the Castle Ice controllers to sync up completely. By this I mean both props starting/stopping in unison.

Also works great for throttle calibration on twins.
