Elithion offers the Vinci LV in a variety of versions, to meet your needs.

Multiple batteries may be managed as a single unit by adding an Array Master.

Elithion also offers accessories (current sensors, communication adapters, pre-made wiring...).

Normally, a battery has a single string in series; a single Vinci LV master will handle that single string by itself.

If the battery consists of multiple series strings that are then connected in parallel, the BMS must monitor each cell in each string.

In that case, the Vinci LV master monitors one of the strings, while a number of slaves monitor the other strings.
For N strings in parallel, you need 1 Vinci LV master and N-1 VinciLink slaves.


  • NOT to be used to increase the number of cells in series: the Vinci LV is low voltage batteries only.
  • NOT to be used for strings that are not connected permanently in parallel: if a string can be disconnected, then it's its own battery, and it requires its own BMS.
  • Not available for Lead Acid.

Each battery requires a protector switch to turn off the battery current and a current sensor.

For up to 20 A current, Elithion offers an internal protector switch and a current sensor.

Above that, Elithion offers these external protector switches.
