330 or 300 Volt Battery?
In all the literature I have read – from Ford http://www.fordvehicles.com/escapehy...logy/index.asp (The sealed nickel-metal hydride (NiMH) battery pack in the FHE is rated at 330 volts) to articles on the net and post here – the battery pack is always stated as a 330 Volt Ni-HM, but mine reads 300 Volts. What gives?? 
I have checked and a ‘standard’ NiMH batteries output is rated at 1.2V (Sanyo Twicell and others). Most articles on the FHE state there are ‘250 batteries roughly the size of a D cell’ - (Car & Driver) ‘250 1.3-volt nickel-metal hydride batteries’ in the battery pack. The 250 @ 1.2V would equate up to the 300 Volts. With the 330 volt output stated most often, that would equate to 275 inline batteries. Am I missing 25 batteries .
On the Sanyo site I did run across some literature on their Twicell batteries at http://www.sanyo.com/batteries/pdfs/twicellT_E.pdf. Seems that both the internal battery and ambient air temp both play a parallel role in correlation with the final output voltage and discharge rate – the higher the temp the higher the voltage/discharge rate etc.
I have seen photos of the battery pack on some sites that have the Sanyo logo on then some with the FMC logo – mine has the FMC logo and reads ‘300V’.
Anyone know what is going on here or if it really makes any difference?
