The Redcat Caldera XB 10E is designed to operate with a 2S LiPo battery (7.4V). Using a 3S LiPo battery (11.1V) can significantly increase the voltage and power output, potentially leading to:

• Overheating: The electronic speed controller (ESC) and motor may overheat due to the higher voltage.
• Component Damage: Excessive voltage can damage the ESC, motor, and other electronic components.
• Warranty Void: Modifying the power system beyond manufacturer specifications may void any existing warranties.

Some hobbyists have attempted to use 3S LiPo batteries in the Caldera 10E series, but this often requires significant modifications, such as upgrading the ESC and motor to handle the increased power. These modifications can be complex and may still pose risks to the vehicle’s longevity and performance.

For optimal performance and to ensure the longevity of your Redcat Caldera XB 10E, it’s recommended to adhere to the manufacturer’s specifications and use a 2S LiPo battery. If you’re seeking increased speed or performance, consider exploring other upgrade options that are compatible with the vehicle’s design.
