The ULTIMATE RV and Marine Battery Module.  This is our most powerful RV/Marine battery module at over 5200 Wh of energy.  This 12vdc, 400Ah battery module is quite  literally bullet proof.0
At 20 x 12.5 x 12.5 inches and 150 lbs, the MILSPEC 12-400 provides 12v systems over 400Ah of capacity, over 3000 amps of pulse power and over 1200 amps continuous, and replaces nearly 600 lbs of lead acid cells.   It is smaller, lighter, lasts 10 times longer than lead and simply does not have the maintenance and operational issues that lead acid or AGM cells exibit.

Permanent Magnet 10 kW BLDC Motor and Controller
Previous1 of 10Next
This is a very interesting and versatile small permanent magnet brushless DC 3-phase motor/controller combination.  Rated at 10kw, this little powerhouse combination  is capable of up to 20 kw of power with full regenerative braking capability and capable of up to about 21 ft-lbs of torque.

Designed for low voltage applications, it runs on a nominal 48v (40-60v) and the motor weighs just 38 lbs.  This is actually the motor used in the 20Hp electric outboard motor.  The motor is 8 inches in diameter but less than 7 inches long.  Ideal for a go-kart, inboard boat motor, etc.

The controller can handle up to 420 battery amps and puts out up to 840 motor amps. 1 inch keyed shaft.

Marine Grade.  This is a very unusual charge controller in that it can charge a battery of a HIGHER voltage than the solar panel output that feeds it.  In this way, you can charge a nominal 48v lithium  battery pack to a precise 56.8v using a solar panel that puts out 33v at its maximum power point.  This is the only device we've found that will do that.

We had these specially made by Genusun in their waterproof casing - fully potted and in a plastic enclosure.  This will last forever in marine/boat applications as well as golf cart canopies or other outdoor in the weather applications.

This one is designed to charge 16 LiFePo4 cells to 56.8v using a Constant Current/Constant Voltage charge curve perfect for our LiFePo4 cells.  

But it can do it from ANY of our flexible solar panels - a single panel. 

Why?  Put a single panel on the roof of your golf cart or the deck of your john boat and use this to charge a 48v battery pack at up to 8 amps.  It could not be simpler.  We haven't seen anything else out there like this "boost" charge controller device.

Flexible Solar Panel 120w
Previous1 of 3Next

This lightweight, high efficiency solar panel is unusually well suited to electric boats, aircraft, RVs and  electric vehicles.  Here's why:  

LIGHT WEIGHT at just 2.45 kilograms - 5.4 pounds each.

VERY THIN - just 3 mm (0.118 inches) thick and built on a very durable flexible acrylic sheet.  This means you can mount it on curved surfaces with minimal wind resistance.  About 30% deflection is possible.

VERY HIGH EFFICIENCY -  20-23%.  This panel is made for EVTV in China using a special laminate. But the individual cells are made in the U.S. by SUNPOWER using their MAXEON back connect technology for efficiencies up to 24%.

What this means is that you can put solar panels in places impractical before.  The lightweight, thin, flexible panels can be attached to RV roofs, boat decks, canopies, and places where the usual 45 lb stiff framed glass panels would simply be absurd.

And since real estate on these "vehicle" applications is limited, paying for the extra efficiency of these superior cells actually makes sens
