But battery cables are 12AWG which is rated up to 20 amps.... Review: I have four of these in ex rental Ninebot max scooters. Ive used both the stock 10s battery pack as well as built my own battery packs of varying voltage. Even with the stock battery the performance is significantly better than the stock speed controller, much more torque and slightly better speed but where this controller really shines is when an option called field weakening is enabled. This will boost top speed on 10s to a little over an honest 30mph. There is a trade off with this and that is increased power consumption, the controller will also quick start getting hot and thermal throttling. I've tried unsuccessfully to resolve the heat problem by several methods. Even with the heatsink attached to a large fan cooled heatsink bonded with thermal epoxy I still run into thermal throttling after several minutes of full throttle. That said, Im pumping close to 3kw through this tiny controller at full throttle. This is a huge amount of energy and is very impressive. I've also been running this on 13s with no problem. Attached are logs of my scooter on 13s. I'm getting 37, 38mph, gobs of power. SI much motor is overheating to the point I drilled holes in the side covers to allow air circulation. It actually works. Lol. ## Features - Comparing with standard FSESC4.12,we made some changesin hardware design.1.Replacecapacitorwhichadopts imported capacitor with better per formanceverifiedbyV6 - Change to use 6PSC authentic power MOSFET(MODEL:NTMFS5C628NL),imported from USA,that are used in FSESC6.6 with reliable quality - Change to use widely Mini USB port,Small Size for wide used,can be installed various products for smaller size and lighter weight - It is a highly modifiable electronic speed controller designed with DIY Electric Skateboards conversions in mind. - Plication areas:Electric Skateboard Longboard Scooter DIY Skateboard ,E-Bike,EScooter ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08725X8CT | | Age Range Description | Adult | | Battery Charge Time | 60 Minute | | Best Sellers Rank | 269,713 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) 577 in Electric Scooters | | Brand Name | Flipsky | | Colour | Black | | Customer Reviews | 3.7 3.7 out of 5 stars (37) | | Deck Length | 67 Millimetres | | Deck Width | 39 Millimetres | | Durometer Hardness | 50a | | Item Shape | rectangular prism | | Item Weight | 76 Grams | | Load Capacity | 100 g | | Manufacturer | Flipsky | | Manufacturer Part Number | Mini FSESC 4.20 50A | | Material Type | Aluminium | | Model Number | Mini FSESC 4.20 50A | | Ply Rating | 7 Ply | | Power Source | Battery Powered | | Size | 39x46x17.4mm | | Skateboard Type | Shortboard | | Skill Level | Intermediate | | Theme | Electric Skateboarding | | UPC | 768111515768 | | Wheel Material | Alloy Steel | ## Product Details - **Age range (description):** Adult - **Brand:** Flipsky - **Charging time:** 60 Minute - **Colour:** Black - **Deck length:** 67 Millimetres - **Deck width:** 39 Millimetres - **Item weight:** 76 Grams - **Material:** Aluminium - **Skill level:** Intermediate - **Theme:** Electric Skateboarding ## Images ![Electric Speed Controller for Skateboard Mini FSESC4.20 50A Base on ESC® 4.12 with Aluminum Anodized Heat Sink 12s esc - Image 1](https://m.media-amazon.com/images/I/61Ixmg8U91L.jpg) ## Questions & Answers **Q: Would a 32v 10s2p battery (a bunch of 18650) be good for this?** A: Yeah you’ll definitely just need to run the VESC tool wizards and go through the configuration which will setup the motor parameters and you can customize the battery cut-off voltages to whatever you need them to be. Hard to say what kind of torque/drive power you’d get out of a nominal 32V vs nominal 40V without knowing your motor specs though **Q: Is this the vesc4.20 plus version?** A: Yes, I believe so. **Q: will this control a 24v 3000w dc brushless motor?** A: Only if it says for a BLDC MOTOR **Q: About the power button? Would I need the anti spark system or will the button they sell that plugs into it work?** A: you need the anitspark ## Customer Reviews ### ⭐ FALSE ADVERTISING *by A***Z on 21 July 2023* Seller claims ESC can handle up to 50A continous current.

If you haven’t solder before do not buy trust me you will regret it. Plus programming it was another struggle on it’s own. ## Frequently Bought Together - FLIPSKY Electric Speed Controller for Skateboard Mini FSESC4.20 50A Base on ESC® 4.12 with Aluminum Anodized Heat Sink 12s esc - Flipsky Brushless Sensored Motor with Pulley for Electric Bike/Skateboard BLDC Belt Motor 6354 190KV 2450W Shaft 8mm High Efficiency Esk8 Motors with High Torque 7Nm Dustproof Motor e-Bike Motor - Flipsky 2.4Ghz Remote VX1 for DIY Electric Skateboard/Long Board Remote Controller with Receiver Universal (V4 Version) --- ## 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.bo/products/258599248-electric-speed-controller-for-skateboard-mini-fsesc4-20-50a-base](https://www.desertcart.bo/products/258599248-electric-speed-controller-for-skateboard-mini-fsesc4-20-50a-base) --- *Product available on Desertcart Bolivia* *Store origin: BO* *Last updated: 2026-05-25*
