Every Frank N Box comes with a one year manufacturer warranty (6 months for NLPWM – see below) for you, the original owner, which includes the board, 510, buttons, etc. as long as parts are still available. It does not cover drops, abuse, charge ports, or excessive amounts of liquid inside the enclosure.

NLPWM Boards come with a 6 month warranty and are only covered as a result of board failure that is not caused by the user. Blown mosfets, capacitors, ripped out wires, etc are all user caused and will not be covered.

The battery is covered if it is a result of a board failure only and must be within 6 months of purchase, but is not covered for degradation over time or if you leave it in the heat and it swells for example.

Anodizing and the finish of the enclosure is not covered as that is considered normal wear and tear over time.

If you sell or trade your Frank N Box, the manufacturer warranty is null and void.

After one year (or if box is not original owner) repairs will still be done at the cost of parts plus a $15 service fee and return shipping cost. This applies to any repair that is user caused as well within the first year.


STANDARD BUILDS – No Customization:  3 Business Days

Any Frank N Box that is ordered without any customization (custom color panels, custom anodizing, or engraving) will take no longer than 3 business days to build provided all parts are in stock. Every now and then lipos are out of stock and/or backordered from the manufacturer. We always do our best to keep everything well stocked, but sometimes we are at the mercy of the lipo manufacturer. Your Frank N Box will ship on the 4th day (provided it is not a Sunday).

Color Panels and/or Laser Engraving: 
14 Days or Less

Any Frank N Box that is ordered with customization (custom color panels, custom anodizing, or laser engraving) will take no longer than 14 days to build and personalize provided all parts are in stock. Color panels take the longest to produce as they need to be designed custom for you by Short Designs and the resin needs time to cure. Please see our Turnaround Page for full details and the production schedule.
