Design with RC Battery 2S LiPo Battery in Cirkit DesignerThe HOOVO RC Battery 2S LiPo Battery is a 2-cell lithium polymer (LiPo) battery designed for high-performance remote control (RC) applications. With its lightweight construction and high energy density, this battery is ideal for powering RC vehicles, drones, and other hobbyist electronics requiring reliable and efficient energy storage.
This circuit is a battery management and charging system for a 2S lithium-ion battery pack, which powers multiple MG996R servos. The TP5100 module charges the battery pack from a 12V power supply, while the 2S 30A BMS ensures safe operation and distribution of power to the servos.

The battery typically includes two connectors:
Connecting the Battery:
Charging the Battery:
Discharging the Battery:
While the battery is not directly connected to an Arduino UNO, it can power an Arduino-based RC project via a voltage regulator or motor driver. Below is an example of using the battery with an Arduino UNO and a motor driver:
// Example: Controlling a motor with Arduino UNO and 2S LiPo Battery
#include <Servo.h> // Include Servo library for motor control
Servo motor; // Create a Servo object to control the motor
void setup() {
motor.attach(9); // Attach motor control to pin 9
motor.write(0); // Set motor to initial position (stopped)
}
void loop() {
motor.write(90); // Set motor to half-speed
delay(2000); // Run motor for 2 seconds
motor.write(0); // Stop motor
delay(1000); // Wait for 1 second
}
Note: Use a voltage regulator (e.g., LM7805) to step down the 7.4V from the battery to 5V for the Arduino UNO.

RC Device Shuts Down Prematurely:
Q1: Can I use this battery with a 3S charger?
A1: No, always use a charger compatible with 2S LiPo batteries to avoid overcharging and damage.
Q2: How do I know when the battery is fully charged?
A2: The charger will indicate a full charge when the voltage reaches 8.4V (4.2V per cell).
Q3: What is the maximum safe discharge current?
A3: For a 2200mAh 50C battery, the maximum safe discharge current is 110A (2200mAh × 50C).
Q4: Can I use this battery in cold weather?
A4: Yes, but performance may decrease below -10°C. Warm the battery to room temperature before use for optimal performance.
