I have 2 X 200 amp VE lithium smarts connected to my BMS CL100 and a deep cycle AGM start battery that is 88 amps 900 CCA on the start battery side of the BMS. It is a 12 volt system. Batteries are located within 2 feet of BMS. What size cables are recommended. Should I follow the wire size for amps and distance or are these connections on the BMS just signal wires?
