Can you not figure out how to test batteries? Ask Fechter. Not sure how to charge batteries? Ask Xyster? Nice job with charging cords, Xyster!

Lithium Iron Phosphate (LiFePO4)
Model Dimensions Weight Price
LFP-40 116Ãâ€â€46Ãâ€â€190 mm 1.5 Kg $100
These cells are 40 Ah; nominally 3.2 volts, although they range from 4.25V to 2.5V
4 cells will make a 12.8 volt pack, and given the 95% efficiency of lithium vs. the 65% efficiency of lead are roughly equivalent to a 60 Ah lead-acid battery.

I've already started bulding the frame for a NiMh bike that would have the "D" size cells hidden inside the frame, but if these are as good as they claim I'm thinking I might drop everything and rethink a new bike.
The price-performance of these looks very good and they look durable and easy to use.
Plus it seems like there has been a big spike in NiMh prices. That sucks! At the very moment I was thinking of buying the batteries the price makes them no longer such a great deal.
