M5Stack Grey charging 16580 LiPo

robouden

Hi all,

I have designed a board with the M5Stack grey on it and the battery is a 16580. But it only chargers at about 120mA. How to set the IP5306 to charge at higher currents?

regards,

Hi Rob

if you look into Power.cpp you'll see that the current already is set to about 400 mA:
https://github.com/m5stack/M5Stack/blob/master/src/utility/Power.cpp

void POWER::begin() {
  uint8_t data;
  //Initial I2C 
  Wire.begin(21, 22);
  // 450ma 
  setVinMaxCurrent(CURRENT_400MA);

are you calling M5.Power.begin() in your setup code?
Or maybe the current has been reduced due the the battery being close to full?

Cheers
Felix
