I never said anything about your bullets or the 1515, just your poor wiring. An electrician's hand book is simply a guide for AC electrical type systems, not electronics as is used in our applications. No Electronics Engineer would suggest you wire like you have. You have over 60 possible points of failure in your wiring/battery setup alone. When running this high a load 2 packs is the maximum you really want to parallel.

Why not ask Patrick or one of the castle techs what they think?

so i need #6? this is the minimum lengths that will fit. where can i get #6 awg wire for rc use? not being sarcastic

or will this be better http://www.robotmarketplace.com/products/0C-WI8Gr.html
hoov! thers mine

hope you did not poke your lipo on your sway bar :(:

I still have 2 to put through their paces but I think my motor is dead. Does anyone have a 1521 1y for sale???

The size wire gauge you use depends on the current draw and the length. If 10 feet of 10GA is good for 50A, 1 foot of the same gauge will be good for higher amperage. Any of those electronics books will tell you that, but probably not as simply. It's about how many ohms of resistance per unit of length. We are dealing with lengths usually under 6" in a typical setup, so that isn't a huge concern.

What I would watch out for is the number of connections you have. Deans are touted as having as much contact resistance as the same length of wire, which is probably true, when brand new. But connectors get dirty and worn over time (Deans, bullets, Powerpoles, whatever) and plugging/unplugging wears on them. The resistance goes up and so does voltage drop and the current capacity goes down. Not to mention all those possible points of failure.

6GA wire with the flexibility of Deans/noodle wire will be hard to come by. I think the biggest I've seen like that is 10GA. If you really think it's a problem, you could always double-up on 12GA on each connection, but it becomes rather clunky and messy.

No, the best/easiest way to handle this would be to use either 12 or 10GA and keep the lengths as short as possible. This might mean you have to rearrange things a little, but it's worth it IMO.

finaly someone who sees it my way! we will se how it goes

Gotta watch inductance too. That's actually just as bad for an ESC as resistance in the wiring harness.

Long wires BAD. Short wires GOOD.

Yeah, there is that...

[emaxxnitro]

ok so as soon as i get my replacement i will try to shead some wire...in about 2weeks

Or get rid of all those crap amps batts away. And just buy some real packs. There will be so many points of that wire job to go wrong. And the car will be a mess.

I just cant see that set up working so well, and have all those wires everywhere would drive me nuts

[emaxxnitro]

cramp amps? i have had no problems with my batterys! i like to see my friends face when i pull off the body to reveal a rat race of wires!

[brushlessboy16]

Or why not just reassemble them into 6s packs to cut down on the extra wire

because i run the packs in other cars

all I picture is this;





just messin with ya!

that made my day
