It supports up to 12S LiPo batteries (50.4V) and delivers a peak output current of 20A, ensuring reliable power for multiple high-powered digital servos and accessories. With adjustable output voltage from 4.8V to 12.5V via Castle Link, it offers customizable power management in a lightweight, durable package ideal for large-scale RC cars, planes, and helicopters. ## Description CC BEC Pro (Battery Eliminator Circuit) is a small device that eliminates the need for a receiver battery. It draws voltage from the motor batteries and drops it to a voltage level that is suitable for your receiver and servos. This is required in applications which use high power servos, where the ESC does not have an internal BEC, or the existing BEC is inadequate. The CC BEC Pro is designed to operate at up to 12S LiPo (50.4V) with a 20A* peak servo load. Generally used for 1/5 scale cars or cars utilizing multiple high powered digital servos, lights, winches and other accessories. It is also useful in larger airplanes using 4 or more digital servos. Perfect for 500 size or larger helis. ## Features - Max Voltage for R/C Cars is 8S (33.6V) - Max Voltage for R/C Airplanes is 10S (42V) - Max Voltage for R/C Helis (with brake disabled) is 12S (50.4V) - Output voltage can be changed via Castle Link (sold separately) from 4.8V to 12.5V. - 1.69" (43mm) x 1.3" (33mm) x 0.94" (24mm) , Weight (w/o wires): 1 oz (29 g) - Max Input: 12S LiPo (50.4V) - Max Output Current: 20 amps peak - Adjustable Output Voltage: 4.8V-12.5V - Max Continuous Current (Input Voltage/Max Continuous Output Current): 16V/15A, 24V/13A, 32V/11A, 40V/9A, 48V / 8A ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002ITEL42 | | Best Sellers Rank | #10,494 in Toys ( See Top 100 in Toys ) #2 in RC Electric Speed Controllers | | Brand | Castle Creations | | Built-In Media | As described | | Color | Multicolor | | Customer Reviews | 4.7 4.7 out of 5 stars (121) | | Global Trade Identification Number | 00899598001717 | | Input Voltage | 50.4 Volts (DC) | | Item Dimensions | 43 x 33 x 24 millimeters | | Item Weight | 0.13 Pounds | | Manufacturer | HRP Distribution | | Mfr Part Number | 010-0004-01 | | Model Number | 010-0004-01 | | Number of Items | 1 | | Number of Packs | 1 | | Output Voltage | 12.5 Volts (DC) | | UPC | 713331839484 605482566916 899598001717 783329010652 885273318898 | | Unit Count | 1 Count | ## Product Details - **Brand:** Castle Creations - **Colour:** Multicolor - **Input voltage:** 50.4 Volts (DC) - **Item dimensions L x W x H:** 43 x 33 x 24 millimeters - **Item weight:** 0.13 Pounds ## Images ![Castle Creations CC Bec Pro 20A 12S Switching Regulator - Image 1](https://m.media-amazon.com/images/I/81dXznR-+bL.jpg) ## Questions & Answers **Q: Csn i ise this woth my teo servos on my 4ws crawler** A: Um... I think I understand the question. It honestly depends on the servo and the load on it. Get an amp meter and test or find out the stall torque amp draw of your proposed servo. Voltage of battery pack is also relevant. EIR look it up. **Q: It has 2 leads im using 6channel receiver can i use Y connector? Or i can use only one lead?help me** A: You can plug 1 lead into battery and y into another channel with servo or just y both battery feeds together but you lose redundancy feature **Q: Hey guys cansomeone help me my spektrum receiver has only 6 channel and this castle pro bec it comes in 2 leads connector toreceiver can i use only 1** A: Use a y-harness into any channel (aileron, elevator, rudder) and have one lead for the y go to the cc bec pro. What I do to get around this is just get 7 channel receivers, but yes, you should always plug in both leads. **Q: Is there any way to program output voltage without CastleLink?** A: Not to my knowledge. Fortunately, I purchased the CastleLink already for programming three 10A BEC and two ESCs before I bought the CC BEC Pro 20A for my Align 550 DFC Helicopter. ## Frequently Bought Together - Castle Creations CC Bec Pro 20A 12S Switching Regulator - Castle Link V3 USB Programming Kit - ONE PIECE - ACE HAT PATCH 2" x 1" --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/300797203-castle-creations-cc-bec-pro-20a-12s-switching-regulator](https://www.desertcart.co.uk/products/300797203-castle-creations-cc-bec-pro-20a-12s-switching-regulator) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-10-20*
