160 The LSPH01 is configured as LoRaWAN OTAA Class A mode by default. It has OTAA keys to join LoRaWAN network. To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and power on the LSPH01. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

1200 LSPH01 is equipped with a [[8500mAH ER26500 Li-SOCI2 battery>>url:https://www.dragino.com/downloads/index.php?dir=datasheet/Battery/ER26500/]]. The battery is un-rechargeable battery with low discharge rate targeting for 8~~10 years use. This type of battery is commonly used in IoT target for long-term running, such as water meter.

1272
1273 (((
1274 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.

1281 (((
1282 You can change the battery in the LSPH01.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.
1283 )))
1284
1285 (((
1286 The default battery pack of LSPH01 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)
