You are exactly right about not exceeding the recommended voltage. And unlike a conventional agm, these TPPL pure leads actually LIKE healthy charge current.
Second thought from a racer standpoint - since you are in a truck, and have less concern about weight and size, perhaps do at least a +1 on the Odyssey. Ie, go from the PC-680 and upsize it to the PC-925. Now you'll get 6 tries at starting instead of 3.
Or, if I put my battery-salesman hat on, I just wonder about a "Plan B". That is, if your LFP bank has an issue, and you are stuck out in the boonies, with only the PC-680 serving as a backup, you might only get 2 hours of life for your cab electronics to work while waiting for rescue. Less if your lights are on trying to fix something. Step over to the counter and let's talk about something much larger in our line. Help yourself to our free coffee!
Heh, looks like Odyssey changed the model nomenclatures on me behind my back while I wasn't looking. It took years to memorize those.
