Car and motorcycle jump starters use 21700 ternary lithium batteries 4S 16.8V. The casing is glued, and only a small 1.8mm screw is needed to secure the charging module. The required material module models are all shown in the pictures. Note: To achieve a slim profile, the screw port of the EC5 plug needs to be modified and trimmed. The switch is for controlling the DC port output and the power display module. DIY involves risks, please ensure safety.
