Power options for Micro Studio Camera 4K G2

Just dove in and bought my first BM camera, the new micro 4K G2. Love it so far, going to use it as a wide shot or hidden cam for live music and theatre. Miles ahead of GoPros and Sony action cams.
In addition to LP-E6 batteries and the included 12V power cord, what are the best recommendations for longer life battery options in the field? V-mount batteries with LP-E6 adapter? USB-C power bank? Looking for best bang for buck. I'm getting less than 60 minutes recording on an LP-E6.
Thanks folks !!
