We are not talking here about E+ Lithum Polymer pack offered by EMS /now recalled for safety reason/ but in general about E+ powered by lithium.
Susan deleted her posts but she was talking about how much better performance of E+ would have been with LITHIUM.

You should not throw all lithum batteries in one bag , EMSs one was faulty construction with inferor Batteryspace cells.
I agree a lot off shoddy lithium out there with crappy China-brand cells.
But there are lot of excellent , lasting lithium also like: A123, LifeBatt, SAFT, CLB, Varta, .
I use BMI cells on my TF for long time close to 4 years now with no hint of deterioration.
EMS Lipoly was lithium polymer type-dangerous and short lasting.
They should have know better.
A123 is my choice of cells for my new lithium pack I will use on my E+. They are LiFePo chemistry lithium and they last years.
NMH cells produce only 1.3V and you need 30 in series versus 12 in series of LiFePo chemistry to produce 36V.
Imagine internal resistance of as many as 30 cells in series?
From basics of electricity.... ... There is no brainer here what is better.
LiFePo can be routinely charged with 10 A charger, try this with NMH!!!
