Well, it seems that Vectrix total failure is imminent, Web sites were all shutdown. Warranties will be lost and spare parts will be very difficult to find in a near future.
Our Vectrix will need repair some day and in that occasion, some of us will forget her and some will try to repair.
For those that want to do the repair, the best chance is try to resolve the problems with the help of Miks' collaborative handbook. Vectux (open source Vectrix) will be more important then ever.
With time it will be inevitable to do a change in the main system. Controller, charger, BMS and batteries should be changed by a better and "open" material. Vectrix has a great structure but without assistance, the "hidden inside technology" must be changed.
The most important on her are the batteries, and these are always getting better. One of the best was announced recently by A123 Systems. The new prismatic batteries have even better capacity that the previous for EVs. They have better energetic density (162 wh/kg) and lower price (45% discount when compared with the actual M1). But there is few information about it yet. The previous M1 are one the best options in the market, yet very expensive. Their characteristics for Vectrix fitting are:
Pack: A123 38s13p - 125.4 volts 29.9 AH;
Weight: About 36 kg;
Volume: 8348 cm3;
Max charge: 136.8 volts;
Min discharge: 106.4 volts;
Recomended charge: 45 minutes at 39 ah /4800 wh;
Recomended fast charge: 15 minutes a 130 ah / 16000 wh;
Continuous Max discharge: 30C ou 900 Ah;
Pulsatory Max discharge : 52C in10 segundos or 1555 Ah;
Life: About 2000 cycles at 2C 100% DOD (Deph Of Discharge), +1000 ciclos at 10C 100% DOD, (in Vectrix, the average will be 2C).
The price of the new ones that will have even better specifications will be about 2700 Euros, that is, about more 900€ that the actual shipped NiMH of the Vectrix and we are talking about one of the best batteries in the market. They are Li-ion and totally safe!

So, won’t be disappointed with the inevitability. Like we say in Europe for hundreds of years, "The King is dead, long live to the King".
Let's work in a solution to produce a better Vectrix based on the Vectux!
(Let's hope that Mik agrees, he is the most important, competent and dedicated person to reveal Vectrix secrets)
