Here is your first look at the amazing Deep Sea Supply Super Sierra Li-On Battery for the Dive Xtras Sierra Scooter.
This is no ordinary battery.
It is designed from the ground-up to take the humble Dive Xtras Sierra and turn it into the lightweight world distance champion. To do this, Deep Sea Supply had to completely rethink the battery design for this scooter.
It had to be powerful, sure. And it is the most powerful battery to ever land in a Sierra.
It also had to be lightweight - as anything over about 14 pounds puts the Sierra out of trim and risks making the scooter negative with the double gauge mount and boltsnap on the nose. Checking in at 13.9 pounds, this battery is negligibly heavier than the standard 16 Amp hour battery offered.
It had to be durable - so the battery case was completely re-designed using the toughest marine-grade components, enabling Deep Sea Supply to squeeze in all the cells and electronics required to get this powerhouse into a Sierra body tube with no modifications required.
It had to be easy to use - so a specially designed, hand-built charger was created that enables the user to quickly and safely charge this monster battery with confidence.
First, the high-level specs, side by side with the standard NiMH Sierra Battery:
This battery made its debut at the Tahoe Benchmark in July 2009. The Super Sierra Li-Ion battery ran away with all distance measurements. This is the battery at which James (Fdog), while on the enuro test, popped up from Lake Tahoe and yelled to the distant shore, "will this friggen battery never die???!!"
Numbers put up by the Super Sierra at the TBM:
Recreational Config - Single Cylinder, Dry Suit
- 182 Feet Per Minute (standard Sierra 16 Ah: 179 FPM)
- 5 Mile* range at top speed (standard Sierra 16 Ah: 1.2 mile)
- 7.5 Mile* range at cruise speed (standard Sierra 16 Ah: 1.8 mile)
Tech Config - Doubles, Drysuit, Deco bottle
- 163 Feet Per Minute (standard Sierra 16 Ah: 160 FPM)
- 3.9 Mile range at top speed (standard Sierra 16 Ah: 1.1 mile)
- 6.0 Mile range at cruise speed (standard Sierra 16 Ah: 1.3 mile)

I have the complete specifications available if you're interested. Just PM me. I've omitted things like number of cells, types of cells temperature ratings, etc. here. Deep Sea Supply provides a very detailed spec sheet that provides that to the owner.
The first thing you'll notice is the Deep Sea Supply Super Sierra Li-Ion battery has only one pigtail - it comes from the top. Unlike the stock Sierra NiMH, you charge and go from the same connectors.
The next thing you'll notice is that although its taller than the standard battery, it weighs about the same. This is due in part to the redesign of the battery case and all components associated with the case. Ounces were shaved, but structural integrity was not compromised. In fact, its clear Deep Sea Supply took a fraction of a fraction off of the diameter of the battery case, as this Super Sierra Battery was easier to install than my new NiMH 16 Ah battery - it just slide right in and locked immediately into place, and mercifully slid right out.
Here is the Super Sierra battery next to a standard NiMH 16 AH batt.
There are warning labels all over the battery and the charger - for very good reason. This battery is a monster. With reasonable and attentive care there is no more risk to the user than from any other battery.
However, the potential for damage or injury is greater for the careless operator simply because this battery is so much more powerful than the normal battery.
The first generation Deep Sea Supply Li-Ion battery featured a pull strap to replace the painful and often ineffective D-ring on the top. This battery maintains that excellent design improvement and features a wide, comfortable pull strap.
