    I'm currently trying to find a battery to power a small amp with the specifications shown in the picture. It has to be rechargeable and relatively light. Any help would be greatly appreciated. Screenshot_20170605-191717.jpg

    Look for an 11.4V Lithium Ion battery. You will need 3000mAH for each hour of operation.

    Be aware that some batteries may not deliver the rated capacity.
    Also, the terminal voltage reduces as it discharges.
    Charts for this should be available online from battery manufacturers.
