Hi!
I’ve been searching around for an external battery that would work with the octatrack - through this forum I found out about the Tekkeon MP3450 but it’s not available anymore.
Found this though which appears to have identical specs -

Has anyone used this - or is there a cheaper option (Tekkeon MP3300?) that anyone can recommend?
Thanks!
