New Form of Transportation!
Make the bicycle or scooter powered by high energy density NiMH batteries, only a few pennies worth of electricity is all your need for miles of silent, emission-free transportation.
In the past several years, because of the lower cost, Lead acid batteries are the major source of electric bicycles, however, the shortcoming of lead acid batteries: heavier, Pb pollution and short cycle life, direct people to green energy of Nickel Metal Hydride.

Pack consists of 10 NiMH DF cells
to make a 12 Volt battery pack. Can
be put in series or parallel. for higher

Advantages of NiMH Batteries:
1.NiMH batteries are smaller and lighter than lead acid batteries, making them a good choice for high performance bicycles and scooters.
2.Over 80% greater run time versus lead acid of the same size.
3.Sustained operating voltage makes the scooter seem to have a fresh charge over most of the
operating time. Lead acid voltage sags continuously over the discharge curve making the scooter
slower through most of the run time.
4.Also available in custom voltages, sizes, capacities, and configurations. This is Vapex¡¯Tech!
5.Low cost compared with other NiMH manufacturers.
6.We set out to design a drop-in replacement for lead acid in personal electric vehicles. This is a
smaller, lighter, better performing replacement, but with a premium cost.
