Soundboks Battery

My neighbor hate me for playing loud music, so I thougt, why not make them more upset with a larger battery. I used eight 32700 lifepo4 cells with 6000mAh for a LONG stable sound.And to be sure that my house didn't burn down, I bought a lifepo4 4s 30a bms (battery management system)The screen is a 7-100V battery indicator from AliExpress. The original soundboks battery has 7,8Ah which you can play around 5 hours on max blast.This battery has 12Ah which you can play about 9 hours on max. To make this battery, you either need a solder iron, or a battery welder.I welded it to be a 4s2p. I used my upgraded Ender 3 S1 to print this, but any other printer would work. I used:Layer Height: 0.16mmInfill: 100%Speed: 200mm/sSupports: None
