Looking to modify my new Apex Pro Rechargeable by building an another 18650 external battery pack. I am looking for a high quality, water resistant 2 x 18650 holder/case with cable and connectors. I have been searching but all I can find are cheap cases and connectors that I don't think would stand up to the rest of the quality of the PT construction.
Does anyone have any experience and/or recommendations for custom external battery packs?
I promise to send pictures when done.
