The BMS 12/200 comes with a 100A fuse in the AB location meaning that 90A only will go from the alternator to the start battery.
In the box came a small pcb.. that fits the fuse location.. it came with 2 x 7.5A (automotive fuses). Do I assume that this in AB location will to about 3A? .. if I have just 1 x. 7.5 A fuse is will limit to to about 5A to the start battery.. and say I put a single 30A fuse in.. it will limit to about 25A roughly?
