Check out this Odyssey Battery, an all singing, all dancing power supply of goodness.
This thing’s perfect for audio installs thanks to its deep cycling application and can even be mounted upside-down.
Odyssey batteries are now being brought into the UK thanks to the Battery Megastore, who also promise free next day delivery.
All you have to do is wander over to their website, choose your weapon, and click ‘buy’!
