Canted coil spring power terminal and sequence connection system

A method of assembling a series of battery modules comprising:

• providing a plurality of battery modules, in which each battery module of said plurality of battery modules comprises a positive male terminal and a negative male terminal;
• capping a first positive male terminal on a first battery module of said plurality of battery modules with an insulative cap leaving a first negative male terminal on said first battery module exposed;
• engaging a first connector in series connection with said first negative male terminal of said first battery module and a second positive male terminal of a second battery module, leaving a second negative terminal of said second battery module exposed, wherein a first insulating housing of said first connector protects said second positive male terminal and comprises a first sequence proximate to said second positive male terminal and an post proximate to said first negative male terminal;
• and engaging a second connector in series connection with said second negative male terminal of said second battery module and a third positive male terminal of a third battery module, leaving a third negative male terminal of said third battery module exposed, said second connector comprising a second insulating housing substantially similar in geometry to said first insulating housing that protects said third positive male terminal, wherein engagement of said first sequence tab of said first connector and a second post of said second connector provides an irreversible assembly sequence.
