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. 696 +))) 695 695 696 696 697 697 698 698 === 2.11.3 Replace the battery === 699 699 702 +((( 700 700 If Battery is lower than 2.7v, user should replace the battery of LSE01. 704 +))) 701 701 706 +((( 702 702 You can change the battery in the LSE01.The type of battery is not limited as long as the output is between 3v to 3.6v. On the main board, there is a diode (D1) between the battery and the main circuit. If you need to use a battery with less than 3.3v, please remove the D1 and shortcut the two pads of it so there won’t be voltage drop between battery and main board. 708 +))) 703 703 704 - 710 +((( 705 705 The default battery pack of LSE01 includes a ER18505 plus super capacitor. If user can’t find this pack locally, they can find ER18505 or equivalence, which will also work in most case. The SPC can enlarge the battery life for high frequency use (update period below 5 minutes) 712 +))) 706 706 707 707 708 708
