    Vectrix 2007 Lithium Batteries State of Charge

    Thanks for your informative response, and sorry for the lack of a follow up for this long time span (life issues). I will look into the LVM wires thing. But there are only two wires (BMS pins CELL and LOOP) connected to the BMS main module (besides the power and ground wires). Yeah, this...

    Vectrix 2007 Lithium Batteries State of Charge

    Sure, I am posting some photos of the bms main module and the layout of the modules of the battery bank (bottom layer). (main module inside the seat compartment, it is been powered by a small 12V battery) (bottom larger layer of batteries inside the vectrix) The battery has about 124V...

    Vectrix 2007 Lithium Batteries State of Charge

    Yeah, I guess I was very unlucky with this bike purchase since the cost of the battery bank is so high. I can not even use conventional deep cycle batteries since the cooling apparatus was removed on occasion of doing the mod. So, eve assuming the battery is worthless and dangerous, the basic...

    Vectrix 2007 Lithium Batteries State of Charge

    Good to know about the DC-DC converter issue, so some sort of contact switch would simply turn off the dc-dc converter. It probably was a conversion, but I saw the vectrix logo on some of them so I assumed that it was OEM. As these the CALB cells you mentioned...

    Vectrix 2007 Lithium Batteries State of Charge

    Sorry for the delay in my follow up, some bad life events... Well, I checked out each cell while still connected to each other and got about the same voltage 3.3V. But I am not able to apply a load since there is "GO" on the display and the bike lists the status of the battery as having no bars...

    Vectrix 2007 Lithium Batteries State of Charge

    So, with the old firmware if the bike seats in storage for too long the lithium batteries would be wasted... That is a bad prospect really. How about source these batteries directly from China (alibaba)? Don't know how easy and cheap to get nissan ones, and on the plus side the ones from China...

    Vectrix 2007 Lithium Batteries State of Charge

    They are indeed LiFePO4 cells with a nominal voltage per cell of 3.2V. I did charge some of them individually, and obtained something near 3.6V on these ones but then most of them I charged as groups of 10 or more and got the equivalent combined voltage of the group with single cells fully...

    Vectrix 2007 Lithium Batteries State of Charge

    Hello Folks, Recently, I acquired a used 2007 vectrix VX-1 max scooter off ebay. The bike came with 40ah lithium ion cells, and it seems that the conversion kit (with the li-ion cells) were bought directly from vectrix itself back in 2010. At first the batteries were completely discharged...
