It is not good to use a high current, short period transmit method. The recommended minimum period for use of this battery is 5 minutes. If you use a shorter period time to transmit LoRa, then the battery life may be decreased. 664 - 665 - 666 - 667 -=== 2.13.4 Replace the battery === 668 - 669 - 670 -The default battery pack of NSPH01 includes a ER26500 plus super capacitor.
