I agree that the oem charging system is insufficient. I have not tried to disconnect the sensor, however it’s said to charge at 14.4v constant if you do, which should be plenty safe for the Odyssey batteries. I ended up buying a NOCO dual bank on board charger to keep them charged up.
They say it can be any battery so long as it is a group 25 size battery. I went with the Optimas since I am in Chicago and according to the video above, the Optimas perform better in cold climate--at least that's what I am hoping for...
Yep you are correct, just double checked their website. Optimas are GTG with the genesis kit
Seems the voltage is 14.7 with the sensor disconnected. I just tried it this morning. Now I'm worried I might be overcharging my batteries on longer multi hour trips...?
I tried it myself for the first time this morning as well. I got an auto start service message and light upon startup. Turned the jeep off and plugged it back in and everything was clear again. In the threads I read I don't remember hearing about disconnecting it causing any warning lights. Did you have this issue when you tried it?
I did not, no. And I specifically made sure to enable ESS on my drive to work this morning, and all is working as expected. Are you also using the Genesis dual battery system like me?
Yes. I'm running a tazer mini with ESS off upon startup, maybe that had something to do with it...not sure.
I'm running the exact same system as well with ESS disabled on startup. It could be your battery voltage, as I've seen that error light and message before when my batteries weren't fully charged with a 12.84V resting voltage. It was intermittent though.
I am having an interesting ESS issue with the @Genesis Offroad installed. I called Genesis and I am told that Chrysler has designed the ESS to stop functioning each 6 cycles. I did not have any issues before but I never counted the cycles and so I find it all pretty bizarre that I am now getting a notice that ESS isn't working and needs to be serviced after installing the double battery setup. So I am puzzled...
You can't be serious. You were told that it is supposed to stop working after 6 start/stop cycles, as designed by Chrysler?
Indeed. That is what I have been told.
Very nice. Are the caps "push through" or do they just bolt on the face of the wheel. Trying to find a 8 hole wheel where I can also use hubcentric rings (which usually aren't compatible with push through caps).
from my research on the forums, battery sizes on ESS JLs are:
