Victron VE.Bus BMS to BMS 12-200 alternator control cable M8 circular connector
 
With this cable the charge control feature of the BMS 12/200 can be used together with the VE.Bus BMS.
 
The BMS 12/200 will limit charge current by the alternator to a safe value, and and stop the charge process in case of an alarm (the Li-ion battery is communicates with the VE.Bus BMS and the VE.Bus BMS transmits to the BMS 12/200)
