Mount the BMS preferably on a vertical surface, for optimal cooling.
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.
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.
Disconnect the cabling from the plus pole of the starter battery.
Pull off the REMOTE on/off connector to prevent unwanted switching of the BMS.
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.
Daisy-chain the battery control cables between the Li-ion batteries and connect them to the BMS.
Connect the plus cabling to the Li-ion batteries and the starter battery.
Reinsert the REMOTE on/off connector on the BMS. The BMS is now ready for use.
