Maxwell BCAP2000E 2000 Farad 2.7V Ultracapacitor

You are bidding on one or more Maxwell BCAP2000E BOOSTCAP 2000 farad 2.7V ultracapacitors. These are the next generation of energy storage, and will eventually replace batteries in many applications. They are very similar to normal capacitors, except they have enormously more energy storage capacity. They have the following advantages over batteries:

• Can be charged and discharged far more rapidly than batteries (almost instantaneously in most applications)
• Not affected by temperature extremes
• Virtually unlimited life (over one million charge/discharge cycles)
• No complex charge controller necessary, just be sure the voltage never exceeds the unit's rated voltage of 2.7V
• Contain no acid or corrosive chemicals

Basic specs:

• Capacitance 2000 farads
• DC Equivalebt Series Resistance (ESR) 0.46 milliohm
• Self discharge 1.2% of stored energy per day
• Operating Temperature Range -40°C to +65°C
• Stored energy 7290 joules (2 WH)
• Max Power 7924 Watts
• Weight .89 lb (405 grams)
• Diameter 2.4 inches (61 mm)
• Height (including studs) 3.96 inches (100 mm)
• Connections M12 x 1.75 threaded stud
• Stud height .550 inches (14 mm) .

  One important application for these devices is for electric vehicle regenerative braking. Due to their ability to quickly charge and discharge, they can recover 80% or more of the car's energy that would otherwise be lost in heat. Batteries generally can recover less than 30% of this energy due to their limited charge acceptance.
  Another application is the storage of solar energy. Many solar applications (garden lights, for instance) quickly fail due to the poor life expectancy of the battery in repeated charge/discharge cycles, poor charge control, and temperature cycling. Ultracapacitors are largely immune to these problems. .

  They are also beginning to be used in space satellite applications due to their robust design and superior life expectancy over batteries.
  These ultracaps are new, unused, first quality items. Two M12 x 1.75 nuts are included with eacc ultracapacitor. Depending on your application, you may need a lockwasher. A standard 12 mm or 1/2 inch lockwasher should work fine.
  We just got a good deal on a load of brand new Maxwell ultracapacitors and modules, of which these are just a part. You can check them out along with our solar and EV stuff by clicking
