I installed the Smart BMS 12/200 with 2x30A fuses for having a maximum alternator charge current of 40A on my 15 years-old CamperVan Ducato 250. I thought that it will charge my 160Ah Victron Lithium-battery with 40A when I am driving on the highway, but it only charged with a maximum of 8A, why? I configured everything according to the manual and the Ducato-alternator can charge with a maximum of 120A... How is it possible to get 100% charge current instead of my 20% ? Thanks a lot!
