Li-Ion 18650 5x1 Battery Pack for My 3D Printer's Backup Power
Description
I Design It To Make 3S5P Battery Pack From Scratch For My 3D Printer Backup Power. I Use 3S 25A Li-Ion Bms Board To Protect The Battery Pack And Connect Its Terminal Directly To 3D Printer'S 12V Power Supply (After Adjusting The Voltage To 12.6V, As Fully Charged Single Li-Ion Would Reach 4.2V, So 4.2*3=12.6). The Batteries Itself Was Cheap Used 18650 Battery With 5A Rating Each. It Did Save Me A Lot As I'M Currently Live In House With Small Rated Circuit Breaker Which Frequently Cut Off.
