CNC oversized fan mounts in 3 colors (black, red and orange) are also available to llow the mounting of the 30mm (3010) fan to maximize cooling during high ambient temperature and humidity race days. With these high tech SMT-MLCC capacitorbanks, neither the ESC nor the capacitor bank will be damaged when reversal of polarity connections during installation of batteries occurs. New Accessory ItemsAccessories like non-polarized capacitor banks and oversized fan mounts can be purchased for the XR10 Pro G2 ESC. Internal Battery-Reverse Polarity Protection CircuitWith the Built-in Reverse Voltage Protection circuit, ESC's internal parts are all protected from Cross Connection of battery power. The XR10 PRO G2 is an exceptional piece of Hardware combined with accurate and powerful software makes this ESC into a "Precise weapon" for high end professional racing. Upgraded M4 Microprocessor (32-bit) for Professional RacingHigh-performance 32-bit M4 microprocessor is implemented in the XR10PRO G2 for Super-fast and precise processing of complicated data operations, this allows the ESC to have a very rapid and precise response with extraordinary potential to optimize and extend its functions further.
