• DIY projects requiring high current output

The following table outlines the key technical specifications of the OVONIC 3s 11.1 V 5000 mAh 50C battery:

The OVONIC 3s battery features two connectors:

1. EC5 Connector: Used for power delivery to the load.
2. JST-XH Balance Connector: Used for balancing the cells during charging.

1. Connecting the Battery:

   • Use the EC5 connector to connect the battery to your device's power input.
   • Ensure the polarity matches the device's requirements (positive to positive, negative to negative).
   • For charging, connect the JST-XH balance connector to a compatible LiPo balance charger.

2. Charging the Battery:

   • Use a LiPo-compatible balance charger with a 3S configuration.
   • Set the charge current to 1C (5 A) for optimal battery life.
   • Monitor the charging process to ensure the voltage of each cell does not exceed 4.2 V.

3. Discharging the Battery:

   • Do not discharge the battery below 3.0 V per cell (9.0 V total) to prevent damage.
   • Use a voltage alarm or battery monitor to track the voltage during use.

4. Storage:

   • Store the battery at a storage voltage of 3.8 V per cell (11.4 V total).
   • Keep the battery in a cool, dry place away from flammable materials.

• Safety: Always handle LiPo batteries with care. Avoid puncturing, overcharging, or short-circuiting the battery.
• Balancing: Regularly balance the cells during charging to maintain performance and longevity.
• Temperature: Avoid using the battery in extreme temperatures, as this can degrade its performance and lifespan.
• Inspection: Check the battery for physical damage or swelling before each use. Do not use a damaged battery.

While the OVONIC 3s battery is not directly compatible with the Arduino UNO due to its high voltage, you can use a voltage regulator (e.g., LM7805 or a buck converter) to step down the voltage to 5 V. Below is an example circuit and code:

1. Connect the EC5 connector to a buck converter.
2. Set the buck converter output to 5 V.
3. Connect the buck converter output to the Arduino UNO's 5 V and GND pins.

// Example code to read a sensor and control an LED using Arduino UNO
// Ensure the battery voltage is stepped down to 5V before connecting to Arduino

const int sensorPin = A0;  // Analog pin connected to the sensor
const int ledPin = 13;     // Digital pin connected to the LED

void setup() {
  pinMode(ledPin, OUTPUT);  // Set LED pin as output
  Serial.begin(9600);       // Initialize serial communication
}

void loop() {
  int sensorValue = analogRead(sensorPin);  // Read sensor value
  Serial.println(sensorValue);             // Print sensor value to Serial Monitor

  if (sensorValue > 512) {                 // If sensor value exceeds threshold
    digitalWrite(ledPin, HIGH);            // Turn on the LED
  } else {
    digitalWrite(ledPin, LOW);             // Turn off the LED
  }

  delay(100);  // Delay for stability
}

1. Battery Swelling:

   • Cause: Overcharging, over-discharging, or physical damage.
   • Solution: Stop using the battery immediately. Dispose of it safely.

2. Battery Not Charging:

   • Cause: Faulty charger, damaged balance connector, or incorrect settings.
   • Solution: Check the charger and connectors. Ensure the charger is set to 3S mode.

3. Low Runtime:

   • Cause: Battery degradation or excessive current draw.
   • Solution: Reduce the load or replace the battery if it is old.

4. Overheating:

   • Cause: High discharge rate or poor ventilation.
   • Solution: Ensure the battery is within its rated discharge limits and improve airflow.

1. Can I use this battery for a 12 V device?

   • Yes, but ensure the device can handle the voltage range of 9.0 V to 12.6 V.

2. How do I safely dispose of a LiPo battery?

   • Discharge the battery completely, then take it to a local recycling center that accepts LiPo batteries.

3. What is the maximum charging current?

   • The recommended charging current is 5 A (1C), but the battery can handle up to 2C (10 A) if supported by your charger.

4. Can I use this battery in parallel with another?

   • Yes, but ensure both batteries have the same voltage, capacity, and charge level before connecting them.

By following this documentation, you can safely and effectively use the OVONIC 3s 11.1 V 5000 mAh 50C battery in your projects.
