I'm looking for a rechargeable battery for a project and I'm not having any luck finding a suitable one. Here's what I need:
The battery will need to be between 12 - 18v with between 1-2 amp. This will be powering a set of speakers, so not really sure what type of amp hours I need. The battery will need to fit into a tin lunch box.
An idea I had was to use a 12 or 18v battery for Power Tools - not sure if it will work though. I also found this, http://www.altex.com/12V-Lithium-Ion-Rechargeable-Battery-Set-LBP-124500-P150057.aspx not sure if it is powerful enough though.
Any thoughts/ideas is appreciated.
