“Heavy” is one of the first words that comes to mind when I think of batteries. Is a Heinkel EV any heavier than a stock Heinkel? Let’s take a look:

Heinkel ICE Parts Removed:

• Engine with swingarm: 111 pounds (with oil)
• Tire and Wheel: 12 pounds
• Gas Tank: 5 pounds
• Gas in the tank (3.25 gallons at 6.1 pounds per gallon): 20 pounds
• Carburetor: 4 pounds
• Airfilter: 3 pounds
• 30 amp starter battery with holder: 20 pounds
• TOTAL: 175 pounds

EV parts Added:

• Battery pack: 127 pounds
• Hub Motor: 66 pounds
• Backing Plate: 3 pounds
• Swingarm with axle: 7 pounds
• Interconnects and rods: 6 pounds
• High voltage wiring: 6 pounds
• Swingarm mount: 2 pounds
• BMS: 3 pounds
• Charger: 10 pounds
• Controller: 10 pounds

The facts are in: a Heinkel EV drivetrain weighs 1/3 more than the original drivetrain, or about 59 lbs (27 kilos) more. Given the performance upgrade that trade it well worth it!
