Convert Most Hybrids
Most hybrids can be converted into plug-ins using our Modular Battery System^TM. Depending on the car, you may double or triple your gas mileage (MPG) or more! Some vehicles are capable of operating for extended periods of time as an EV, at a variety of speeds from city to highway speeds.

You can also add extra battery capacity to some EVs using our modular battery design.

Product Features

• Systems are made using high quality, high performance, long-lasting components.
• All systems allow access to the spare tire.
• Public charging station (fast charge) compatibility is available (J1772, etc.).
• Our Modular Battery System^TM is easily moved from car to car, without a hoist, eliminating the worry of payback on your investment.
• All systems are available as Do It Yourself (DIY) or Ready To Install (RTI).

With a Plug-In Supply lithium iron phosphate add-on battery pack you get true plug-in performance at a fraction of the price of a new plug-in car and with much greater range — up to 7 times the electric range.

Announcements

• New modular battery design gains immediate acceptance
  Our new modular battery pack design is what everyone wants. Since its introduction, few have ordered our original aluminum battery box for the 10 KW Prius pack. The new modular battery design provides many improvements: access to the spare tire, the pack can be installed by hand without a hoist, you can move packs easily from car to car. The modular design makes it easy and safe to work on a high voltage battery. Each module has its own plastic box, fuse, and quick connectors to quickly isolate it from the rest of the pack and the car.
• Modular Battery Packs with cylindrical or prismatic cells
  We now offer Modular Battery Packs built using cylindrical or prismatic cells. This allows us to offer many sizes of packs for all kinds of applications. For example, you can buy or build the following packs for the Prius: 4 KW, 5 KW, 7 KW, 10 KW, and 15 KW. These are available as DIY and RTI.
