Design with SparkFun LiPo Charger Plus in Cirkit DesignerThe SparkFun LiPo Charger Plus is a compact charging solution designed for lithium polymer (LiPo) batteries, which are commonly used in portable electronics, drones, and DIY projects. This board simplifies the process of charging LiPo batteries by providing a micro USB port for power input and a JST connector for the battery. It also includes status LEDs that provide visual feedback on the charging state. The charger is designed to be user-friendly and is suitable for hobbyists and professionals alike.
This circuit consists of a TP4056 module connected to a 3.7V LiPo battery, providing a charging interface for the battery. The TP4056 manages the charging process by connecting its B+ and B- pins to the battery's positive and ground terminals, respectively.

This circuit is a battery management and power supply system that uses three 3.7V batteries connected to a 3S 10A Li-ion 18650 Charger Protection Board Module for balanced charging and protection. The system includes a TP4056 Battery Charging Protection Module for additional charging safety, a Step Up Boost Power Converter to regulate and boost the voltage, and a USB regulator to provide a stable 5V output, controlled by a push switch.

This circuit is a portable power supply system that charges a 18650 Li-ion battery using a TP4056 charging module and boosts the voltage to power a Raspberry Pi 3b+ via a DC/DC booster. The TP4056 module manages the charging of the battery, while the DC/DC booster converts the battery voltage to a stable 5V output for the Raspberry Pi.

| STAT | Status LED indicator (Charging: Red, Charged: Green) |
Q: Can I charge multiple batteries at once? A: No, the SparkFun LiPo Charger Plus is designed to charge a single LiPo battery at a time.
Q: What should I do if the battery starts to swell during charging? A: Immediately disconnect the battery from the charger and place it in a safe area away from flammable materials. Swelling can indicate a damaged or faulty battery.
Q: Is it possible to power a project while charging the battery? A: Yes, the SparkFun LiPo Charger Plus allows for pass-through charging, enabling you to power your project while the battery is being charged.
// There is no direct interaction code required for the SparkFun LiPo Charger Plus
// when using it with an Arduino UNO, as the charging process is standalone and
// does not require microcontroller communication.
// However, if you wish to monitor the charging status via the Arduino, you can
// connect the STAT pin to an Arduino digital pin and read its status.
const int statusPin = 2; // Connect STAT pin to digital pin 2 on Arduino
void setup() {
pinMode(statusPin, INPUT);
Serial.begin(9600);
}
void loop() {
// Read the status of the charging process
int chargingStatus = digitalRead(statusPin);
// Output the charging status to the Serial Monitor
if (chargingStatus == HIGH) {
// When the STAT pin is HIGH, the battery is not charging
Serial.println("Battery is fully charged or not present.");
} else {
// When the STAT pin is LOW, the battery is charging
Serial.println("Battery is currently charging.");
}
// Wait for a second before reading the status again
delay(1000);
