Burnt VX1 LiFepo4 update from 2013

7 years ago • updated 7 years ago • 2

Hello,

I just had a second hand Vextrix Vx1, updated by Vextrix in 2013 to lifePo4 (36 32Ah LifePo4 cells) with x4 BMS boards on top. One of the BMS board was literary black burnt and the 200 amp fuse was blown too. Also 32 cells were completely broken, they do not hold any charge and they are inflated like balloons.

The charger is a EVPS (Runke) , but dont know the revision yet.

Now, I bought 18650 li-ion cells to build 36 cells of 62Ah, and my doubt is with the BMS:

- get one of the stock BMS boards for the 9 cells wouldn have one.

- get your BMS for Vectrix VX1.

Would you recomend a solution or configuration for may case?. If a get the BMS from you, do I need to change or update the charger or can I keep it?.

best regards

Alex

Hi Alex

I recommend you our new BMS system - http://shop.vectrixparts.com/vx1-bms-board.html

Improved and fully protected - no more problem with connecting / disconnecting from battery. Firmware with setting for 36S Li-ion

You don't need to modify charger, but if you need shorter charging time - we offer now 3.3kW unit.

We will provide you also latest firmware for charger and MC - for Li-ion version.

If you send us drawing or picture of your new battery pack we can even preapare you custom battery to BMS wire harness.

To use stock VX-1 BMS board you will need an adaptor board - we use to sell them, but no more interest so we don't keept them on stock - http://shop.vectrixparts.com/vx1-bms-adaptor-pcb-case.html.

Dear sir/madam,

Thanks for your reply. I ll be very interested defenetly in the BMS. I am still waiting for my cells, as soon as I had them I ll send you the drawings and I ll make the order for the BMS.

I ll be also interested in updating the firmwatr for the charger but will keep it as charging time is not an issue.

How much will be the BMS to send to Spain?

thanks for everything.

Regards

Alex
