I've actually been setting the PrecisePlus 18500 up based on what
batteries they intend to run in them (the shopping cart has a drop down menu so you can choose IMR 18480 or P18500 battery set Up). You can change the setup to run either.
Heres the setup, so keep this post in mind for later quoting and reference:
PrecisePlus 18350:
- When running AW IMR 18350 (only battery i recommend for it). One .100 thick Oring under the battery and one washer under the switch contact post.
PrecisePlus 18500:
-When running AW IMR 18490 run two .100 thick Orings under the battery and 4 washers under the switch contact post
-When running AW Protected 18500 run One .100 thick Oring under the battery and one washer under the switch contact post
