After trying contacting Vecrix team over email, posting here, opening a private ticket, nobody came back to me. So, don't spend your time waiting for the reply here.  

Sorry, spell checker, Piotr... 

Hi Peter, I'm currently running 19 Leaf modules with latest Dugas firmware. It's 2007 VX1 with ESD charger. No other mods on a bike. Would you please suggest what options I have for the BMS from you? 

Andrei.
