, I didn't see a settable current limit. Do you have an idea yet of the peak current in the charge line?
No, I ran two conductors of 1/0 from the battery in the engine bay to the rear bumper using Anderson SB175 connectors at the bumper and trailer side...with their environmental boots and a WitsEnd SB175 mount bracket. Works great.
I haven't measured the current on the truck side of the system. With a 145A OEM alternator (2007 Chevy Silverado Classic HD2500) I can see a larger alternator will more than likely be needed.
Downstream I plan to install a higher output Mechman alternator to relieve the strain (2-FLA starting batteries + 200Ah LFP in the bed + the 400Ah/6500w LFP in the Escape. Mechman has a 250A unit that utilizes the same OEM diameter pulley but puts out 180A at idle. For our extended stays in remote camp spot I'd like to have the ability to utilize the truck's alternator for primary re-charging of the LFP in the bed and the Escape.
