Castle CC BEC 2.0 15A Max Output 14S (58.8V) Waterproof

use this to feed 12V directly to my motor fans, works perfectly

A must have when getting into crawler competitions.

Great

I love this thing! I previously had the non-waterproof version in my E-Maxx running two high voltage servos, but I wanted a fully waterproof truck. Now I have over 550 oz-in of torque and my BEC doesn't struggle to keep up. It will take up to 12s direct voltage so there's almost nothing you can't hook it up to. With up to 15 amps, this thing could run high voltage servos, a winch, and full light kit without breaking a sweat. Best of all, it's absolutely tiny! You could mount this anywhere. It's about half the size of the previous non-waterproof BEC and it's got a solid aluminum case. I bet this thing is virtually indestructible. Just hook it up to Castle Link and select your output voltage. I loved this so much I bought a second one! This one went in my crawler. There is a tiny bit of flickering from my LEDs when I turn the servo, but I have 13 LEDs on the truck and two of them are high power so that's a pretty big draw. I'm also using a high torque Savox power hogging servo and one fan. Compared to the stock 5-amp BEC on my ESC, it makes a huge difference.

This works very well as a BEC. I have two of them. One of them was put to work as a servo battery on a very large servo that I used to convert a Minn kota trolling motor to radio control.
