    An 18km breathhold is probably a record. Even for you.


    Just sayin....

    This sounds like one incredible battery.
    The MiniCuda Battery is the same cells in the same package, but they are arraigned in groups of 10 cells in parallel. 12 of these 10 cell groups are in series to provide the higher voltage the Cuda Motors operate on.

    The total watthours of the two packs are the same, 22.2 volts x 52 amphours = 1154 watthours = 44.4 volts x 26 amphours.

    Because the Cuda motor is more efficient you will get more range at the same speeds a Sierra can reach, and because the CUDA motor is also capable of higher output you will also have the potential for much higher speeds.

    Compared to a "650" NiMh Cuda the Li-Ion MiniCuda offers just under twice the battery capacity, and higher speeds due to the higher battery voltage.

    The NiMh packs are nominally ~40.8 volts and the Li-ion packs are nominally ~44.4

    The potential for higher speeds with the Li-Ion MiniCuda does impact range, if you use the higher power settings you will burn a lot of watthours fast.

    The MiniCuda is a blast, 43 lbs., faster than a NiMh Cuda and potentially twice the range of a 650. The ultimate shore diving scoot.

    Tobin, could a mini Cuda be packed for travel and keep the weight under the 50lb limit?

    Thanks for giving me battery envy for the scooter I don't even own...

    Depends on the packing of course, but the scooter with the battery is a bout 43 lbs.

    Keep in mind these batteries don't fly on commercial passenger planes.

    Eric, I will agree that a competent freediving scooter pilot will be quite a bit faster.

    Our data points to a 33% to 36% speed increase over a drysuited diver in a single. Assuming equivalent speeds, this would produce 1.92 x the range.

    Which is still pretty impressive!


    All the best, James

    Are there ways of shipping these batteries to travel destinations overseas?

    Course by the time I get around to getting one I'm guessing the cuda mk 3 will be out and you'll have a battery with 2-3x the burn time

    18km... feeling lucky punk?

    So THIS is what it takes to bring THE Eric Fattah out of lurkerville?! Welcome to DMX bud - lots of Liquivision lovers here.

    I bet we could talk Eric into demoing the saddle on one of Tobin's fancy new batteries.

    It can be done, but it's a bit involved. Also depends on *where* you are going.

    I think DSS should make some NiMH idenitification stickers and sell them on the DSS website... you know, to put on our NiMH scooter batteries and HID batteries to identify them to TSA when we travel.

    DSS stickers would be way cooler than Airspeed stickers (not that there's anything wrong with Airspeed, I'm just a DSS homer).

    Someone putting a DSS NiMH sticker on their Cuda monstah Lithium Ion battery... now we have a battery smuggler in custody at TSA as well as someone knocking on DSS' door asking them about why they're mislabeling batteries after smuggler goober tried to pin the rap on Deep Sea Supply.

    Never gonna happen.


    I'm quite shocked Airspeed has their name on the sticker most of us are using. I'm sure Airspeed has thought better of this in the current litigious culture we're in today.

    DSS just sells the stickers... And Tobin didn't put it on the wrong battery. ;-)

    How many of you have actually read the Airspeed Press sticker? What does it REALLY say? Yes, my batteries are "dry cell" batteries -- that is true -- but hey, what does that mean?
