    PLEASE NOTE: This mechanical tube extension is wired in series, meaning that your maximum voltage (4.2V) will be multiplied by the number of battery cells in series, which does the same to your amperage load as well.  As such, series mechanical mods require extensive knowledge and familiarity with both Ohm’s Law and battery safety/amp limits in order to be used without risk of damage to yourself or your surroundings. If you are at all unfamiliar with these two subjects, feel free to drop us a line and we’ll be happy to either provide additional information on these matters or suggest comparable alternatives, such as an unregulated device wired in parallel.

    This product does not carry any warranty and we only guarantee that you will not receive it DOA (Dead on Arrival).
