3.3.2 Replace the battery
You can change the battery in the LSN50V2-D2X.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.
The default battery pack of LSN50V2-D2X 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)
