Victron Battery Management System BMS 12/200

Victron Battery Management System BMS 12/200

1. Mount the BMS preferably on a vertical surface, for optimal cooling.
2. Determine the rating of fuse AB (see figure and table 1). The fuse on input AB doubles as a shunt. The BMS will limit the input current according to the rating of this fuse. Choosing the right fuse will prevent overheating of the alternator and/or DC cabling.
3. Determine the rating of fuse LB. This fuse should be rated in accordance with the expected load current and the cross-section of the cabling to the load.
4. Disconnect the cabling from the plus pole of the starter battery.
5. Pull off the REMOTE on/off connector to prevent unwanted switching of the BMS.
6. Install and connect all electrical cabling and fuses AB, and LB, but leave the plus poles of the Li-ion batteries and starter battery disconnected.
7. Daisy-chain the battery control cables between the Li-ion batteries and connect them to the BMS.
8. Connect the plus cabling to the Li-ion batteries and the starter battery.
9. Reinsert the REMOTE on/off connector on the BMS. The BMS is now ready for use.

Notes:

a) A battery charger can be connected to input AB instead of the alternator.

b) The Li-ion batteries can be charged as well as discharged through input/output LB.

c) When a load with a large electrolytic capacitor bank (such as an inverter or inverter/charger rated at 1200VA or more) is connected to LB, the BMS will limit its average output current during start-up to approximately 80A. Therefore the capacity to simultaneously start up other DC loads is limited to 80A. Once the capacitor bank is fully charged, the current limit increases to 400A.
