Nickel Metal HydrideBatteries NiMH

A nickel metal hydride battery, abbreviated NiMH, is a type of rechargeable battery similar to a nickel-cadmium (NiCd) battery but has a hydrogen-absorbing alloy for the anode instead of cadmium. Like in NiCd batteries, nickel is the cathode. A NiMH battery can have two to three times the capacity of an equivalent size NiCd and the memory effect is not as significant. However, compared to the lithium-ion battery, the volumetric energy density is lower and self-discharge is higher.

Lithium-Ion Batteries Collaborative Hand Books ( A123, Dewalt, etc.)

Lithium-ion batteries (sometimes abbreviated Li-ion batteries) are a type of rechargeable battery commonly used in consumer electronics. They are currently one of the most popular types of battery for portable electronics, with one of the best energy-to-weight ratios, no memory effect and a slow loss of charge when not in use. They can be dangerous if mistreated, however, and unless care is taken their lifespan may be reduced.

For those of you who have been following this build, here are some pics of some of what I have accomplished lately.

MB-1-E Part Seven: Securing the batteries connecting them up.

Hey everybody,

The past few days I've been pretty busy, so didn't have a lot of time to get a much work done on the Mountain Bike.

After working with the acrylic enclosure for a full afternoon, I abandoned the idea. I got all the pieces cut and started gluing it up and then simply changed my mind.
