Yes cell means the battery.
The gold plated laser your ordering screws apart in the main body. You can keep it long and use 2 18650's or unscrew the body and not use part of the host to use 2 16340's. Look at the pic's on the link and you will see.
Most lithium battery's we use are to be charged 3.7V to 4.2V. Just get good battery's like Efest and you will be fine. Make sure they are "button tops".
