Technical Performance

The Traxxas XL-5 ESC delivers exceptional performance through a carefully engineered combination of advanced electronics and thermal management. With an impressive peak current rating of 100 amps in the forward direction and 60 amps in reverse, plus a braking current capacity of 60 amps, the XL-5 can handle motors ranging from 15-turn 540-size to 12-turn 550-size brushed units—the most common motor configurations found in UK RC cars and trucks. The continuous current rating of 14 amps ensures sustained performance during extended runs, whilst the ultra-low on-resistance specifications (0.007 ohms forward, 0.014 ohms reverse) minimise power loss and heat generation through the switching MOSFETs. The 1600Hz PWM frequency creates seamless, stepless throttle control that competitors often reserve for high-end racing ESCs. Battery compatibility spans both traditional 4-7 cell NiMH packs (4.8V to 8.4V DC) and modern 2-cell LiPo batteries (7.4V), with intelligent two-stage low-voltage detection protecting LiPo packs from dangerous over-discharge. The built-in BEC supplies 6.0V DC at 1 amp to your receiver and servo systems, eliminating the need for secondary battery packs and reducing overall vehicle weight and complexity. At just 87 grams (3.07 ounces), the XL-5 is remarkably compact and lightweight, making it suitable for installation in compact chassis designs including short-course trucks, buggies and stadium vehicles. The high-capacity heat sink and efficient MOSFET design keep operating temperatures low even during aggressive driving sessions, whilst the automatic thermal shutdown protection safeguards the unit if temperatures exceed safe operating limits. For UK RC enthusiasts seeking reliable, feature-rich speed control at competitive pricing, the XL-5 represents outstanding engineering and value.
