Can any one tell me about the battery system I have on this model?

Thank you for the reply. I purchased this unit last year and haven't touch it. It was originally purchased here in the States for police vehicles for the then President Obama's inaugural parade. It only has 60 miles on it.

I'm not sure if all these units are equipped with wifi and blue tooth, but this one is.

The problem is I cannot get it to take a charge by the factory plug. 

Any idea where I can get more information on getting it to charge?


If the scooter was not use a long time, it is possible that battery is completly discharged. Try to measure the pack voltage(It is voltage on whole battery. In your picture it is plus wire and minus wire on right side) and let me know. 


This is a very amazing post.  I found so much information from your site. Godaddy $5.99 SSL Certificate keep doing a great work.

I just bought a VX-1 that belonged to one of the initial investors of Vectrix. It is said that he rode it once and parked it. That was 2010. I would love to get it up and running...any insight as to where to start...? Thanks...Riley in GA


Did he charged it periodically? If no, there is huge chance that we will have to rework this battery.

Please contact me directly via e-mail.

hello i have the opportunity to purchase a lightly used 2014 vx1. Any idea on battery replacement/upgrade costs or sourcing ?


Thanks for publishing the informative post. i am really enjoyed while reading this valuable post. keep up posting. Linenspa coupon codes

can I get some help with a VX-1 battery possibly.  Like one of the other people posted on here I have a VX-1 that the previous owner did not charge for over a year.   He said it ran fine prior to that but not it is not accepting the input from the internal charge.  Any help would be appreciated 

Please write to me more details. 

Type of battery and charger.

year of production etc.


Are you still in business?  Any info on service in USA?  Thanks!

Hi all , I need some help to get my vectrix vx-1 to life . Can not charge and want to figure out is my batteries are good  or need new one

Thank you 

Hi. I think this is wrong post but I can't find one abouth converting vx2 from 2011 with gel batteries to lifepo4. I wold like to know if I can just switch batteries and charger or I need to do more on the scooter to höger it running? 


the links for shop.vertixparts are not working.

do you know why??? It is close maybe? Or is just some days manteniance?

thanks in advance,


Hi, most likely it is permanently closed. It is already unreachable for a while.

I can give a link to a copy of the site. Nice to get the ref number of what you might order. You can join Matteo by mail to order. If available.

We have a reasonable stock of spare parts here in HU. Even so it would be great if you can share that link, should there be a need for some items from Matteo.

Houston, Texas, US - I think... is that right?   I don't know what a "winrar" is, nor "bms" nor "Itio 36S"...   I'm just an owner, rider - not a technician...  Is there a different forum I can access?

I'm hoping service will be available in the US before I need to replace my 2014 battery...  so far it's good - but just 20-25 miles per charge..  still useful for city.   If anyone has information about battery upgrades, adaptation of LEAF, Tesla battery etc - I'd love to know - but in non-acronym, plain language, please.   Thanks

it is possible tu buy one bms for conversion to ltio 36S? 

Hello,  from France.  Yes, BMS is available. From Fran . I try to get his website.

Hello, Fran site. email at the bottom of the page.


Thank you very much :) 

maybe you can help me with another problem too, my vectrix is not showing signs of life is there any way to tell if it's just the battery? maybe by connecting a 120v dc power supply you can see if the electricity works? or is there some other way maybe with the motorcycle charger ... I tried to plug it in but nothing happens any advice is welcome

You can apply 110-150 V DC indeed to the battery terminals indeed to check if the bike powers up. You will need to use an incandescent 40-100 W light bulb inline to prevent excessive inrush current that could damage the Motor Controller.

In the majority of the cases it is the battery. The rest of the Vectrix is quite reliable maybe with the exception of the chargers.

It is with pleasure that I tell you that my vectrix is still alive powered by a power supply and turned on everything, keeping it a bit there the battery is back up enough to start the scooter's charger, bathot appears on the dashboard and unfortunately the battery does not hold the voltage and discharges immediately, now my project is to make a new S36 P10 battery with 5 AH 21700 cells, my charger and an ESD (silver) charger with square connectors is it possible to reuse it? if so how? do i need a bms? If so, which one ?

any advice is greatly appreciated this is my first experience with this scooter, thank you for the previous answers and for those to come

Great. Yes you must* have a BMS for Li-ion cells, check the link Sylvain shared, that is the improved version of the original Vectrix design.

The ESD charger is quite old and far from ideal for Lithium. Even so it is kinda possible to use it with the so called Dugas software and firmware, however there is no guearantee it will work nicely with the above BMS mainly due to firmware compatibility issues. A gold charger (aka Runke v2 or v3) would be much better since those are proven to work with the BMS.

* In a nutshell the BMS controls the charger preventing overcharge and takes care of the balancing session as well.

I don't know where to find the Runke charger, to start it would be better to modify what I have, there is a tread that explains how to do and where to download Dugas software and firmware?

Sure, you can find some details here : https://visforvoltage.org/forum/14235-problem-dougas-engeneering-firmware. If you drop me (me@mecano.hu) an email I can send you the files. Note, you will need a specific CAN bus adapter as well : https://www.peak-system.com/PCAN-USB.199.0.html?&L=1&no_cache=1&sword_list%5B0%5D=ipeh002021 (the opto isolated one).


hello, Fran has a complete offer. BMs, charger ect that seem to be better than the originals. It seems Dugas firmwares causes a lot of charger breakdown. Fran's not. Never heard about problems.

Once you have the the Vectrix Diag app talking to your bike it is strongly recommended to take a note of the original firmware versions in case you need to roll back. The risky part is the Motor Controller firmware change, absolutely no disruption is allowed during the process. Should the image download fail in the middle there is no easy way to fix the MC (only by low level reprogramming the processor). Never broke for me though.

it seems that I have found a Runke, as soon as it arrives I start the work and I will certainly have other questions, if you like the forum I will publish the photos of the works for the moment thanks to all

Great, make sure it is V2.1 or V3 for Li-ion.
