What are the individual cells ?
Are they each 42Ah and ?? In series, or some other capacity and configuration ?
Size ?
Thanks

Pack is 40 cells in series, specs of cells in link below but no longer available.

Probably vectrix is not to confident to sell these cells any longer, wonder why

Now looking for the best solution to give the vectrix a second life, a lot of possibilities but always a lot of $$$.

Thanks,
This guy used modified Tesla modules....also expensive , but very solid result.

Tesla conversion is a blast, also leaf-cell conversions seems very good.
An alternative is an 18650 conversion as in following link.

The easiest way to go is to order the 30ah GP-cell they still offer at vectrix, but are they any good? I'm not too sure about that. If you see the state the 42ah cells are in after just 5 years ...

Like the diy approach of the 18650 conversions out there because of the flexibility of it, would also like to stick with lifepo4-chemistry so i don't have to change anything to the current elektronics and settings although energy density is less than li-ion, but range isn't that of an issue to me.

Still a lot of reading to do before i start building a battery pack.
