774
775 The Li-SICO battery is designed for small current / long period application. 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.
776
777
778
779 === 4.3.2  Replace the battery ===
780
781 You can change the battery in the LMDS200.The type of battery is not limited as long as the output is between 3v to 3.6v. 
782
783 The default battery pack of LMDS200 includes a ER26500 plus super capacitor. If user can’t find this pack locally, they can find ER26500 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).
