We need three things:
1) An on/off button to cut power.
2) A battery monitor that will cut power when the battery declines to 12v or 50% (for lead-acid).
3) A plug to connect the battery recharger to the battery.
The new Bike Party system contains:
(2) JBL GTO939 GTO Series 6×9″
(1) Skar Audio SK-M4004D Class D 4 Channel Car Amplifier
(1) Pioneer MVH-X390BT Digital Media Receiver
(1) Power Sonic 12V 35Ah U1 AGM Solar Battery
We will be testing out a lighter battery shortly:
(1) FirePower HJTX20HQ-FP Featherweight Lithium Battery
