How to Insert the Battery

18650 battery and charger required!

The PLT-1B does NOT include a battery nor a charging circuit. You will need to supply your own flat-top, unprotected 18650 Li-ion cell, and a separate 18650 charger. Recommended cell: Samsung 30Q 18650 3000mAh.

1. Gently press your thumb on the case above the stake and the lid should pop off.

3. Flip the PLT-1B over and identify the + and - markings. The + is on the left side and the - is on the right side. Double check before going any further.

4. The top of the battery (the positive end, marked with a + and a small ring around the terminal) goes on the left side, matching the + on the PLT-1B.
