Vectrix 18650 Lithium Conversion

Hi Guys

I thought I would share with you my resurrected Vectrix that has been sitting dead for years now.

It now has 1140 x ICR18650-25C cells (2500mah) in a 30P38S configuration. Total capacity 75ah or about 10.5kw/h

Minimum voltage is 104.5, max is 159.6

I don't really have the right firmware for these parameters (I'm using Lairds firmware for ESD charger 19 Leaf cell - charges to 157V then turns off, and the MC1014bB_70_110_140_CC.hex motor controller which lets me discharge down to 110v, but doesn't allow regen above 140V, which is most of the time) - if anyone has any advice on firmware I'd really appreciate it!

Also, if anyone can advise how to get more power out of it ( I have read that some people get up to 240amps draw from the battery. my max is 208amps at around 140V - approx 28kw. 240A would be nice!!

BMS is an aliexpress 24s bms with bluetooth and 1a balance current (two of these to allow for 38s).

I have given the bike a colour change, it looks lovely I think!

Performance is great, handles really well. I did a 100km ride through the hills, windy roads, and consumed 6kwh. Batteries hardly warmed up at all.

Here it is before the colour change and no batteries...

Removed the panels

Tried to salvage the "electric" decals. I think they are an important feature as far as looks go.

Swapped the 125a fuse with a 200a fuse..

Unfortunately I didn't get a pic of them with the connector bus bars at the ends of each module....

Painted. Colour is Blu Cepheus

Decals re-applied, very lucky to not damage them when removing.

Color looks great!

If needed, you can reprint the decalcs!

Thanks.. I have seen these new style decals. They look like the decals on the new re-released VX1

But how / where to get decals in the original style - metallic silver with black border. I don't think they exist?

I don't need them as my originals still look good.

I do need the rear decal though, the one at the back on the grab handle.

Very nice conversion. I am using a 32 cell 90 ah pack made out of 4 EV modules so about the same capacity as yours. I use the Dugas Engineering free firmware and it has worked very well. I had a different pack that charged to just under 160 volts and the ESD charger handled it fine. I think 160 v is the most the charger can do. You can configure for various numbers of cells and set LVC and regen voltages. Easy to use. As far as increasing the power I doubt that can be done but Dave Dugas would probably know. dugasengineering-com.3dcartstores.com/Vectrix-Support_c_16.html

good luck!IMG_20181227_182115(1).jpg

Re: Vectrix 18650 Lithium Conversion

Oh. The amp draw will depend on what pack voltage you are using. When the pack is fully charged you will see less amps for the same power than you will see when the battery is near discharged. The acceleration is always the same no mater what the SOC is so I have always assumed that the controller is limiting watts not amps. The most amps I have seen was 240, but only for a split second. So expect to see the highest amp draw at low SOC. Your pack voltage is more than a stock bike so you would not expect to see as high an amp draw. That is how I understand it but I am no electrical expert.
