Thanks for all the discussion! I have 20 CALB cells mounted in the front trunk (ex gas tank location) and 30 in the (middle) engine compartment, inverter is in the rear trunk. I have the most positive in the front, running through a shunt and a 500A Kilovac contactor to the controller. The most positive wire is where I had the single Airpax before, mounted in the classic EA kick panel position. That has been re-done with a direct wire to the controller input. I've been working on putting a series pair of the breakers in the motor compartment to act as a service disconnect between the two 15 cell boxes on either side of the motor.
I have two of the EA fuses (LKN 250V, 250A times 2, stamped "For 500A use 2") , one is installed in the middle of the front pack, the other is slated to be in the middle of one of the 15 cell packs, I'm thinking I should have one more for the second rack. Anyone have a good source for those fuse links? I'm thinking I should be using LKS 500 V links, but LKN is what came with my EA setup. I found some 150A Kilovac contactors cheap, so I will set them up to disconnect the charger unless plugged into an AC source and also to disconnect the DC-DC when charging. One question, is it overkill to put another contactor on the most negative lead to the controller? I was thinking of having the battery pack completely disconnected from everything while charging, well, everything but the shunts for the E-Meter and the ammeter.
