No. The first- and second-generation Song Meter Mini and Song Meter Mini Bat do not support external batteries.

However, the following models support up to six 18650 lithium-ion batteries, allowing for internal battery runtimes longer than any previous Song Meter model:

• Song Meter Mini 2 Li-ion
• Song Meter Mini Bat 2 Li-ion
• Song Meter Mini 1, with Li-ion lid accessory
• Song Meter Mini Bat 1, with Li-ion lid accessory

Using six lithium-ion batteries and standard settings, these models can record 1,330 hours of audible sound, and the Bat recorders can monitor up to 125 ten-hour nights.

For even longer deployments, the Song Meter SM4 and SM4BAT FS recorders support external power from the Wildlife Acoustics Power Kit or third-party power sources.
