16. A method of forming a system of cordless power tools comprising:
-
providing a battery; providing a terminal block with a main body and a plurality of battery terminals; electrically coupling the battery terminals to the battery; slidably inserting the terminal block into a first recess in a first battery housing shell and the battery in a second recess in the first battery housing shell; and coupling a second battery housing shell to the first battery housing shell to retain the terminal block and the battery therebetween; wherein the electrical coupling between the battery terminals and the battery is the sole physical connection between the terminal block and the battery before the terminal block and the battery are received in the first battery housing shell.
