ESC Capacitors
 

I just picked up some 35v 330 UF caps for my MM, and i forgot which way there soldered on... Anyone care to share how they went again?
would appreciate it.

Caps are marked with a "-" which is connected to the neg main power input.

Use a meter to see which side is -ve check for continuity between the negative side of the power and the solder points.

And they should be soldered as close to the ESC as possible for max benefit. Here is a thread that shows how I did my Quark. I know it's a different ESC, but the principles are the same: http://www.rc-monster.com/forum/show...91&postcount=2

griffin ftw!

Whats the difference between caps with say a 330 Uf and the same voltage caps with like 1800 Uf... Is it better to be closer to whats stock on the MM? or should i go all out and get a big cap with a high Uf number?

uf is the capacity of the capacitor. Bigger the number the more energy they can store. Having one 2000uf cap is the same as having 20, 100uf caps. However, I believe having less caps is more efficient.

So would you say having 2 or 3 330 Uf caps is better than having 1 1800 Uf Cap or something in that range?

i would say the more the better because the more surface area will help with cooling. but on the otherhand u have slightly higher resistance

Surface area of what??

Thats the opposite of what he said...

2x330=660
3x330=990

or just 1800Uf and you surpass have 2 or three, and with what he said about having less is more efficient, having 1 1800Uf is obviously more efficient and better. At least thats what I got from what he said...

i ment more cap surface area for better cooling

I assume he means the total capacitor surface area is larger, which reduces heat.

However, I personally have never had a capacitor heat up anything over room temperature. I used 3 25v, 2700uf capacitors wired in series with my HV4.5 and they added a significant amount of punch, as well as lowering my ESC temps a good 10* F.

Thats what I thought he meant, but it didn't make any sense since they shouldn't heat up...

Ahhh thanks for the help guys... appreciate it... now if i can find my camera when i hit up the track on friday... ill post a small vid :yipi:
