Connecting an external 3.7V lithium battery to the M5StickPlus

  • I would like to connect a 2200mAh small LiPo battery to the M5StickPlus. Can I connect it to the BAT and GND pins of the M5StickPlus directly? I do not need to recharge it as it is for a one-time use for an event. Do I need to remove the internal battery of the M5StickPlus?
