I know someone (probably Mik) published the battery pack currents for various loads, but I can't find the information again.
Have been thinking about replacement batteries again and it seems the 24, 36 and 48V lithium packs from manufacturers such as Ping are quite limited in discharge currents.
So I wondered how many strings of (10, 15 or 20AH) packs in parralell would be required to supply the peak currents that the original NiMH cells can provide. Quite easy to do the capacity calculations and then work out if the resulting series/paralell packs will fit in the 700 x 330 x 230mm battery bin.
If for instance, a continious current of 80A and a maximum of 120A peak is sufficient, then two strings of 6 x 24V 20AH LiFePO4 Ping packs would fit in the existing VX1 battery bin, with room for seperatots to allow cooling air flow. All this for about $8530 Australian.
Charging is an entirely different matter, which I don't want to think about at the moment.
A simple calculation of power devided by volts indicates however that at 16kW and (nominal) 125V then 128A would be required to push the Vectrix along.
Just need to know the currents provided by the old cells.
