I ordered this last night and got a ship notification this afternoon. I wanted to go a bit simpler than the standard setup plus its a bit cheaper. My main concern is the stock system is not isolated when the vehicle is off potential greatly reducing battery life especially considering that the 2 batteries are not the same size and make.
Goals:
-Make the Aux and main batteries the same size/model
-Isolate the batteries when the ignition is off
-Retain ESS battery isolation during an ESS event
-Have all accessory loads connected to the aux battery
-Have more power in reserve for winching
-Have the rear 12v outlet run off the aux battery when batteries are isolated
Special thanks to @Jebiruph for all the diagrams you have made. Its making figuring this out a lot easier.
Diagram of my plans(Sorry hand drawn)
I'm currently planning to use a Cole Hersee 24231 200 amp continuous duty solenoid to Isolate the batteries. I will eliminate the wire from n3 on the PDC fuse bar to the PCR to the Aux battery. Replace N1 to aux positive with a longer cable.Reuse or replace N2 to main positive. Tap a 12v switched ignition source from the fuse box to trigger the battery isolation relay through a secondary normally closed relay that will be triggered by the factory PCR trigger wire. Also going to keep the IBS sensor on the main battery and ground with the aux battery. All add ons will connect to the aux positive.
I've seen that you can make the rear 12v outlet hot all the time by moving a fuse. Does anyone know if this is powered by the aux battery via N1?
I'm also not sure what batteries I'm gonna go with. Most of the group 25's are 550 CCA's and I don't want to go that small.
I'd love to do the Odyssey's but they are expensive. I don't really want to spend that much on a wear item. Exide and Bosch make AGM group 25's with decent CCA's but they are not available to me locally or online plus the Exide has bad reviews. Looking at the Optimas good CCA's and they should fit but will be loose in the tray without a spacer. They also have less than stellar reviews since the factory got moved to Mexico. However I can get a pair shipped for $330. That leaves NAPA Legend 625 CCA's regular lead acid but slightly longer than standard group 25's @ 9.75" currently listed at $112 each + core at my local Napa. Will measure to see if they fit once I get the tray. Anyone know of any other options out there?
