I have a Sound Devices MP2 where I have used Energizer Advanced lithium batteries to power my 460s. With the SD MP2 Set at P48, the 460's got consistent 15 hours of run time. Around the 16 hour mark, is when I always lost power.
Question: Would I really beat 15 hours if I changed it to P15 on the SD MP2? Or are the 460's configured as power-sippers and it doesn't matter what I have the phantom power set at? Please advise. Thanks.
