Juicebox with voltage display

To power Arduino controlled Lego models I used Li-on battery for which I designed this box. It consists of a 11.1V / 500mAh battery with Voltage Display and switches.

To recharge the battery I just have take of the power cable and connect both cables to the charger.

Battery: 3S Lipo 11.1 V 1500 Mah 35C
Switch: 10*15mm SPST 2PIN ON/OFF
Micro Switch: Tactile Self Lock Dpdt 7*7 mm
Voltage Display: three digit 0.36 "'LED digital, 21.5x13x8mm (L * W * H)
