MKR 1010 Battery

[afnansb_233]

Hi
I am using the following code to monitor a 3.7V 800MAH lithium battery to power my MKR 1010, and I have all the required library. However, this code always shows the battery percentage as 100, do you have any idea how to solve?

#include "Battery.h"

Battery battery(2750, 4200, ADC_BATTERY);

void setup() {
	Serial.begin(9600);
	while (!Serial);
	analogReference(AR_EXTERNAL);  
	analogReadResolution(10);
	battery.begin(3300, 1.47);
}

void loop() {
	Serial.print("Battery voltage is ");
	Serial.print(battery.voltage());
	Serial.print(" (");
	Serial.print(battery.level());
	Serial.println("%)");
	delay(1000);  
}

Hi @afnansb_233, I would suggest you this Arduino tutorial to follow. It is quite easy to read and guides you through the steps to solve your issue in another way.
