thanks guy's, I think I might have to pinch this paralleled esc set up, I like the idea of disconnecting all the babberies with just the one connector.
Now you just need to buy another Ice esc and throw some good 4s packs in to series up 8s 2p for a total of no more than 12000mah and get a good pair of 3 blade props and go SAW racing ! You can take S or T offshore for the record ! Easily....
Go for it ..it seems to work good at delivering equal juice ...the boat runs straight as a arrow.

There are just two harnesses one positive and one negative consisting of: 1 bullet with 4 wires soldered together behind it with each wire going to a same polarity battery lead on each 6s pack

snap a picture if you can, so I can clear my head on this one a little more
I just looked hard at you parellel set up... Caught a potential performance robber ! The way you have paralleled all of your power threw 2 bullets is going to take away from your C rating and will cause your caps too work overtime ! Your motors will potentially draw way more than what a single + &- bullet will deliver to 2 motors ! I would definatlly change that, you want to deliver full C rating especially when eccelerating and when using bigger props. You will run cooler and you will gain efficiancy and speed too ! I appoligize if I missunderstood the way you explained how you were going to parrellel to me or if that is how I described too you the way I parrelleled.....I did it that way trackside at LA SAW so I could power 4 motors with 2 packs just so the quad could be legal to run....I would definatlly change that Brian for performance resonses.....
That is a single bullet for + & - or is it one of those -+ double conecters used for double positive and one for double - ?

I should double up the bullet connectors ... 8mm will probably flow 250a continuous, so four of those ought to be sufficient power delivery. You know what really has me thinking is how to wire in a data acquisition device like the eagle tree v4 150amp ...I would only get one of them, and I'm thinking of abandoning the esc parallel and choosing a side to drop in the eagle tree device...it goes in-between the battery leads and the esc. Any suggestions?
Yes 4 bullets into the esc's. 2 packs parrelleled into 2 bullets each esc with 2 8mm bullets and run a jumper wire conecting - & +'s on the esc side to parrellel everything( can probably use smaller guage wire for this, 12g should do)....I am not sure of the amp logger. Is it passive or does all current going to to esc have to pass threw it ?

Randy thanks for the pic ...that seems like a good design ....I will leave it setup the way it is for a few more runs because the performance seemed to be there already ...I just need to run it harder. If I notice the caps getting real hot or bulging, or the connectors in question getting warm I will change it. The Eagle Tree logger is active in that all current must flow through it, in from the battery and out to the motor. I have read where people are using it in systems that are running more than 150amps continous but I know that hooking it up to this system between the batteries and the two paralleled escs would be way over 150amps ...my guess would be around 250amps continous at times. Millzee, I am definitely a newbie trying to get things worked out ...mostly through trial and error....I'm even trying to work my own props, sanding and balancing...but that's a whole other discussion I figure that I'm less than a month away from a video featuring my Conquest drag racing the Sniper 0-60mph that is my ultimate goal

That conquest is going to show the sniper what time it is !!!.......

do you know what your runtimes are?
I'm going to guess about 75-85amps cont. per side for a total of 150-170amps cont.

The runtime is 7mins ...the batteries used a little over 4000mah each so 16000mah total....thats and average of 137amps ...I have never looked at a log chart of amps over time for a boat ....what do you think the motors are pulling under heavy load?

hey I was close!
I would guess twice what your average is for the peaks
