Mackie GB-10

Rechargeable Battery for ProFX10 GO Mixer This rechargeable GB-10 battery gives you up to 8 hours of high-headroom analog mixing with the ProFX10 GO mixer. It's the same GB-10 that comes with every ProFX10 GO, so it’s a perfect replacement or spare. When one battery runs out, swap in the spare to extend the battery life.
