There is nothing inherently more dangerous about Li-ion or Li-poly than
NiCd and NiMH.

Many of the problems that have hit the news have been due to
manufacturing faults. Because the cells in these batteries are
different from the standard cylindrical configuration, manufacturers
have had to re-tool in order to manufacture them. This is the first
major re-tool in a very long time, and it's just taken a bit of time to
iron out some difficulties.

The advantages of Li-ion are huge - much higher power density, no heavy
metal content, great charge-discharge characteristics, the list goes on.

For a glimpse of what can be done with Li-ion, take a look at this:

Very impressive, would love to see it go

My only worry is there are NO mechanical brake. Fully reliant on
software/hardware for the regen braking!!!!

Don't worry about that..... Grunff wrote the software. He's very good :-)
