Safety Precautions:
The JTES Lithium Battery can be used to power an Arduino UNO via its VIN pin. Below is an example circuit and code:
// Example code to blink an LED using an Arduino UNO powered by a lithium battery
// Ensure the battery voltage is regulated to avoid damaging the Arduino
const int ledPin = 13; // Pin connected to the onboard LED
void setup() {
pinMode(ledPin, OUTPUT); // Set the LED pin as an output
}
void loop() {
digitalWrite(ledPin, HIGH); // Turn the LED on
delay(1000); // Wait for 1 second
digitalWrite(ledPin, LOW); // Turn the LED off
delay(1000); // Wait for 1 second
}
| Issue | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Charger not compatible or faulty | Use a charger designed for lithium-ion batteries with CC/CV charging profile. |
| Battery overheating during use | Excessive current draw or short circuit | Reduce the load or check for short circuits in the circuit. |
| Rapid capacity loss | Overcharging or deep discharging | Use a protection circuit and avoid exceeding voltage limits. |
| Battery not powering the circuit | Incorrect polarity or loose connections | Verify polarity and ensure secure connections. |
