I build cooler stereo/radios. I use similar led strips for the builds. Slightly more expensive, but WAAAY lighter and come with charger and each battery has a switch built in. These run LEDs, speaker amp, and speakers for over 10 hours (the 6.8 Ah) on the river. Oh and they're lithium so better obviously.
Awesome build but toss an extra $10-30 and you'll have a better battery.
If you love your motorcycle, set it free. If it comes back and hits you, you high sided.
"Gave my 500ml Pacman starter that I made last night a hug and wished it a good day before I headed off to work. He's growing up so fast!! Will be a 2liter starter by Saturday and will probably start ignoring me, think he knows it all and end up knocking up some skanky belgain strain before I know it." ~BigTerp
