@rpn314 has some good questions.
A couple things to note - you cannot run those motors (230kv) @ 12s on your VESCs. VESC only supports 12s with motors <200kv. You will kill your VESCs if you try.
You can run your 3s packs in series x 3 for 9s - that should work really well for you. I ride regularly on 8s without issue and i’m a big guy. Especially w/ dual motors = lots of power!
iCharger chargers are my favorite. I have the 306b if you have any specific questions on them let me know. I’m sure i can help with 206/208/308 as well depending on model you got. What power supply did you get to power your iCharger? I have a couple - from a 600w variable output, to dual dell server 750w in series for 24v.
what motor mounts, wheels, and gearing do you have? How much do you weigh, and what kind of riding are you planning (flats, hills, etc.)?
recommend a loop key or anti-spark loop key as the simplest way to connect your batteries and disconnect them when not riding:
If it’s helpful i can show you pics of a few boards i built - so you can see how i wired and placed everything?
First board test setup (painters tape for the win!):
(Battery (single 6/8s 8Ah iirc) --> Watt Meter (unneeded, just for info) --> VESC (w/ GT2b Rx next to Watt Meter) --> DIYes 5065 200kv. Paris 195 trucks (eventually used on other board in dual rear setup), ADS original motor mount, 12/36 gearing (motor/wheel) 9mm belt. Got quite a bit of skipping on 12t front gear - i use 13/14 now as a result as lowest.
Same trucks (Paris 195’s) - setup dual rear w/ ~5mm spacers to fit 5065 motors:
And complete board on a ride:
(GBomb, custom Subsonic deck, 97mm flywheels - awesome board until stolen out of car!)
GF’s setup now:
Dual 3/4s - Wiiceiver/Kama Rx/Tx - VESC - 200kv 6355 motor (generic) - Enertion mount and 14/36. 83mm flywheel clones w/ Caliber II 50’s.
That’s pretty much the progression of my boards from taped up testing to a relatively “finished” board my GF rides.
I have a Marbel i ride most of the time (since GF’s on hers), and am still building a few other setups. Another single motor guest board, a single motor setup to send home w/ a buddy in SoCal who will be visiting EOM, and my dual motor GBomb replacing the stolen one (bigger, better, faster, stronger).
