12.6V battery pack 6x18650

Hello I made this 12V battery pack box to use it with 12v soldering iron outdoors. you can use it for all 12v devices like car vacuum cleaner or air pump or water pump, all you need is to make cable adaptors and conectors. fill free to remix it :) I used 0.75mm^2 (or 20 awg) wires for my own battery pack. I recommend you to not use thinner wires then this because of high current. part list: print- 1x Part2Battery_Pack_MAIN_ASSEM 1x Part3Battery_Pack_MAIN_ASSEM 1x battery_bracket_1 1x battery_bracket_22 2x Part1Battery_BMS_Pack_Assy buy- (I bought from AliExpress) 1x KCD1 23MM Round Rocker Switch 2Pin 1x T Plug Female Deans Connector 1x 0.28 inch DC LED Digital Voltmeter (DC 2.5-30V with 2 wires) 1x 3s 40a balanced BMS 6x 18650 3.7V li-ion betteries -charger- 1x Battery Charger 12.6V DC Lithium Li-on Power Adapter -cable adaptor parts- 1x T Plug Male Deans Connector 1x 5.5mm x 2.1mm Male DC Power Plug 1x 5.5mm x 2.1mm Female DC Power Plug 1x XT60 plug 1x Car 12V socket
