Wildlife Acoustics announced the release of their new Lithium-ion Battery Lid kit last week. We are pretty excited to be able to supply this kit as you will be able to record for up to a phenomenal 1,100 hours with 6 lithium-ion batteries (18650), in comparison to 215 hours with 4 AA batteries. It is worth noting that you have the option of using 2, 4, or 6 lithium-ion batteries to power the Song Meter Mini Acoustic/Bat.

The video below explains how to fit your kit:

Top tips:

  • The cell needs to be between 68-69 mm to ensure contact
  • The cell should be protected 18650s to avoid over-charge/-discharge
  • Ensure that all batteries are charged fully and equally before use
  • Do not mix batteries of different types, or old with new
  • Always remove batteries prior to long-term storage - protect batteries and terminals by covering them with insulative, non-conducting electrical tape or by storing each battery separately in a plastic bag
  • Please do not send the 18650 batteries with your unit in the post - for instance when you send your device in for service and repair
