Last week the kit including the BMS arrived. No circuit or wiring diagrams, just a pile of parts. Hmmm...

The BMS consists of a module for each battery cell and a "control unit" if you can call it that.

The BMS components are from EV-Power. Here is a link: EV Power cell module.

I am trying to figure out how to fit the battery. The original plan was to put 32 cells arranged as 2 rows of 16 in the bottom of the battery compartment. However, they don't fit.
At the rear, welding lugs from the frame's rear casting are protruding. I am prepared to grind some of that away to make the cells fit side by side.

Received the battery. 42 CALB CA66Fi cells, 66Ah. 32 of them go into the battery compartment standing up as 2 rows of 16 and the remaining 10 will be stacked flat on top, most of them where the impellers used to be. Unfortunately the supplier forgot to send the interconnects. Next week then...

After having been convinced by Matt Lacey's Li conversion videos that a Li conversion is quite managable, I started looking for a 2nd hand VX1.

By good fortune, I ended up with a VX1 from the former Australian Vectrix importer and distributor. The bike is ex-demo/showroom and I have been told it has done less than 500km. It has a few marks and the chrome plated surfaces have brown corrosion spots. The battery could find a new application as a zero-volt reference if it were not so heavy, and since the plan always was to convert to Lithium, I did not even attempt to revive it.
