Hi there,
here is the the link to GP´s datasheet of our Vectrix-cells: GP30EVH
@ Mik: somehow I managed to add this to the col.handbook. Pleas check if I did the right way and place...
@ all recomendet discharge 60A continuous and !90A! pulse (5 secs!!). This is one reason i don´t want the 68mph upgrade puting
the cells above their limit. I try to contact my nearest dealer for a testride with the 50mph firmware. The other interesting fact: servicelife is about 1500 cycles (80%DOD at 1C).
Greetings Mike
These specs are a big worry.
Even with the 102km/h max software the maximum current draw far exceeds the specified max current draw. It's peak is way over 200A at full acceleration at 75km/h.
The max regen charge current is also higher than the specs.

There is always a way if there is no other way!
Check the specs on the NEW vectrix cells? Gold Peak, #GP30EVLF. It seems likely that a 60 AH package could be fitted, doubling the single-cell specifications!--->50 miles, at 60 MPH anyone?---I want it!!!--Bob Curry

that would do for me.
GP obviously changed the specs.:
Weird!
I downloadet the datasheet yesterday from GP. Well there are differences in max current-draw,
min. discharge temperature and other specs. both the single cell- and the 12v module-specs
seem to be identicel. maye the changed the specs to the lower values, because of problems
with cell lifespan, or they changed the internal structure of the cells?
Has anyone a god contact to GP?
GP contacts worldwide
Greetings Mike
I think we don't really know what cells are in the VX-1 !
All I have seen were data sheets for cells that look like the Vectrix VX-1 cells - but that's where the certainty ends!
Small changes to the chemical composition of the electrodes and/or separator and/or electrolyte can make massive differences to the specifications of the cells.
The names are different, too: There seems to be a different number at the end of the cell names:
GP30EVH vs GP30EVH04
The devil is in the detail!

Has anyone seen a pricelist for this table?
The AndyY1 link to image on Shrani.si http://www.shrani.si/f/27/MQ/wGsyHFc/nimh.jpg
is for 10/GP30EVH04
And Google found a pdf version on same site: 10GP30EVH04
This shows bottom of page with Date: 01/2004 and the Doc Prop's with

GPINA.com is 10/GP30EVH also NB the 04 is missing.
This has green footer and header
Also footer info shows: ERS0130 Rev1

Then this one linked to Here on VisV only has green Header but same:ERS0137 Rev1
http://www.evbtech.com/Data%20Sheet%5CTDS%2010GP30EVH.pdf
This shows bottom of page with Date:ERS0137 Rev1
The pdf DOC properties show: Microsoft Word - ERS0137 TDS of 10GP30EVH09 rev1.doc

So this version looks like release 09 of the spec.
The ..04 and ..09 extension could be the year.
The Weight has changed from ..04: 8.2Kg to ..09: 8.6kg
And internal resistance: ..04 <14mOhm fully Charged to ..09 <12mOhm (But this info is probably for impedance at 1kHz not DC)
And Temperature info too.
Charge and Discharge curves an recommendations are different
..04 has 3A to 9A, and
..09 has 6A (0.2C) to 15A (0.5C)
and graphs are more generic in later version and miss the 3C rate.
It did seem strange that they had sprooked the 350A Max Discharge in the early version.
That's over 11C rate but as a 1sec pulse its feasible with the disclaimer "with Ventilation Cooling".
Things may start to fuse out over that.
But as the disclaimer says on the bottom, Not for Warranty purposes.
