Gen 2.0

Still the highest thrust DPV available with an unequaled top speed, it just got a lot more fun to dive. We added inlet guide vanes to the propeller that eliminate ALL torque at ANY speed. The torque on the original Genesis was a bit fatiguing after a few minutes at full power, but not any more. Since the toque is gone, we also reduced the handle height by just over an inch, as you no longer need the extra leverage. You can now control the DPV with only one finger at full power. Three clear polycarbonate inlet guide vanes at 3, 7 and 11 o'clock positions on the nozzle struts provide the perfect amount of force to eliminate torque from the prop.

As always, the Genesis is still the only DPV with external recharging, so you don't have to break the hermetic seal on the DPV every time you need to recharge. It's also still the only DPV with single handed full variable speed control and a maintenance free magnetic shaft coupling, but the big changes are on the inside.

Introducing the Warp Core Battery system.

Warp Core 2.2

• Jon Nellis
• Dec 7, 2019

The Genesis Warp Core solves the main problems with DPV Batteries. No longer do you need to rely on someone else's proprietary battery packs when they eventually wear out. The Warp Core uses replaceable 18650 flat top cells available all over the world. It is made up of individual circuit board layers with 8 cells per layer (95Wh), stacked together for the necessary voltage and capacity. The individual layers are UN38.3 tested in both 2S4P and 1S8P configurations, meaning the DPV can be taken on passenger aircraft and checked as baggage, after simply removing the jumpers between the layers. The batteries do not need to be removed from the DPV and hand carried, like power tool batteries. Finally, a real high performance travel scooter with serious range. ...and we do offer a travel case for the smaller sized Genesis.

Additionally, the Warp Core has a Bluetooth app (Android only) that lets you check the charge of the battery as well as the voltage of each group of parallel cells. You can also monitor the charge/discharge current and check cell temperature from your phone, along with a host of other features.

The Genesis 2.0 will now come in 2 sizes. The Gen 2.1 will have 850 Watt hours and be the same size and weight as the previous 600. (24" long and 33lbs) Gen 2.2 will have 1700 Watt Hours and be about an inch shorter than the previous 1500 and under 50lbs. If you want to switch between 850Wh and 1700Wh batteries, additional layers can be added/removed. You would just need the shorter or longer DPV body.

We don't leave our loyal customers out in the cold with a new design. Current Genesis owners can have their DPVs refitted with the Warp Core, but it does require sending their DPV in for rewiring and other changes from the previous 2 battery system.

The Warp Core PCB uses proprietary high contact force cell holders designed to fit flat top 18650 cells. Every single cell is fuse protected for safety, in addition to the Warp Core BMS. More space between the cells means better cooling than tightly packed and sealed cells.

Our Plan is to eventually make the Warp Core system available as a retrofit into other brands of older DPVs using 8" tube bodies (Sierra, Cuda, N19, Magnus, etc.), but those could most likely be a couple years out, if not longer, as we would need to reverse engineer the mounting into the different designs.

We are planning to start shipping the Genesis 2.0 January 2020. Pricing is not available just yet, give us a week or two for that.

HOLY SMOKES! That's quite the game changer.

Are those cells user replaceable without soldering/welding?

YEP! The cells are replaceable without soldering/welding. For the UN 38.3 Testing to remain valid when the cells are eventually changed, they need to be replaced with Panasonic NCR 3300mAh 10A rated cells or similar chemistry. (+/- 10% capacity)

5-7 years down the road, instead of paying $2000-$3000 for a big proprietary battery, replacement cells for the Warp Core will cost you $350-$700 and you can get them almost anywhere. 72 cells in the small pack and 144 cells in the large pack. Operating cost just got A LOT less expensive. ...AND YOU CAN TAKE IT VACATION! Even the large one!

So if I send in my current 1200 will I need a new tube for the 1700 sized batteries?
Or will you be producing an extension tube so my 1200 body becomes a 1700?

There's a couple options. You could use your existing 1200 body as is and just leave out a cell on each layer to save weight, which would give you about 1500Wh or you could add an extension ring to get the full 1700Wh.

We have an extension ring available, but there was a change between 2012 and 2013 that reduced the tube weight and have not yet tested the slightly heavier 2012 tube to see if the extension provides enough lift in freshwater.

Hi, Nellis, when using Genesis Warp Core for charging, is it still necessary to connect the tail of the motor to charge it, or can a charger with independent charging be used? If there is an external independent charger to charge it, then I just need to replace it The battery can be quickly returned to Genese.

 

[Jon Nellis]

The Warp Core battery still recharges through the waterproof nose plug on the front of the DPV. Removing the battery to recharge would defeat the whole point of having a sealed DPV that you do not have to open to charge. Just plug it in during your surface interval, same as the original batteries.

The Warp Core charger outputs around 280W, which is faster than most divers consume power on a normal dive. The original Genesis charger output around 200W, which is still slightly more than normal power consumption during a dive. If you dive it for an hour and charge it during your surface interval, you'll be back to almost a full charge for your next dive, without having to open the DPV, and you can do that all day long. I've done 5-6 dives a day on a liveaboard with a 600. Just plug in the charger to the nose of the DPV as soon as you get out of the water, go have snack and off-gas, and then unplug it as you get in for your next dive.

Opening the DPV repeatedly to recharge, just increases your chances of getting debris on the seals that can cause a leak. Over the years, I've found that dog hair is the #1 cause of leaks. Do a good job cleaning and greasing the seals before closing it up and then leave it sealed. We have some customers that dive 2-3 days per week and have not opened their Genesis in YEARS.

Mr. Nellis:

I do a fair amount of diving at Point Lobos. I've found myself many times doing circuits to Great Pinnacle or to Twin Peaks. With doubles and two deco bottles per diver, can the Genesis 600 2.0 tow two peope to within Whaler's Cove, from those two locations, with ample speed and reserve power in the batteries? If I had been on the trigger for 30 minutes at 150ft/min (doubles and deco bottles). How long can I expect the DPV to run at full power until the batteries are depleted and the scooter stops?

 

[Jon Nellis]

Without having any more information, the phrase "You mileage may vary" has never been more true. If you and your buddy were 5'8" 160lbs with decently streamlined drysuits, I'd say no problem. If you are both 6'8" 280lbs with baggy drysuits and poor buoyancy, maybe not. It is all about diver drag and I've never seen you or how you dive, so there's now way to answer those questions with a 100% guarantee.

For reference, I'm 5'8" 155lbs, DUI Flex 50/50 w/ leg pockets. Diving side mount, I'm typically around 190 watts for 150fpm. In a wet suit, I'm down around 155 watts for the same speed, wet suit and single tank, I'm down around 125 watts. If I had a better streamlined drysuit, my power usage would drop. I've dived side by side with some people on Genesis that use up to 30% more power to go the same speed, because of their riding position, gear drag and buoyancy control, and a few divers that use less power than I do. Towing a buddy, really depends on how streamlined you can get. If they grab on right behind you and put their head below your tanks, their view will stink, but you'll use a lot less power than if they are on a 6ft leash behind you, where they can see.

As for run time at top speed, that is the most frequently asked flawed question for comparison, since other DPVs can not reach the same top speed. Run time at top speed on the Genesis 2.1 is only about 50 minutes before it drops into reduced power mode of 300 watts for another 30 minutes. If you reduce the power down to the same max speed of slower DPVs, the run time will be longer. If you really need to run a DPV at full max power to minimize deco obligation on a dive profile, you should be looking at the 2.2. Very few divers need that, but we have a few that do. Also consider that other DPVs cannot actually be run at max continuous power for an entire battery discharge, because they will overheat the motor inside. Every DPV we ship goes through a factory burn test in a water tank, running continuously at 100% max static thrust until the motor controller goes into low power mode when battery charge gets low. The Genesis motor cannot be overheated.

Finally, you should dive plan your DPV battery capacity, just like you dive plan your breathing gas supply. Rule of thirds, at a minimum, for critical dives. Most divers are completely oblivious to this, as they have no way to track or manage battery consumption. We recognized this years ago and it's why we were the first to come out with a DPV dashboard, the Sentry.
