I will need to leave my 2021 F150 Hybrid stored for 3–6 months. I am considering leaving the battery on a trickle charger such as the NEXPEAK 10-Amp Smart Fully Automatic Battery Charger, 12V and 24V, Maintainer Trickle Charger w/Temperature Compensation. Any recommendations if this is a smart way to leave the vehicle, or should I just disconnect the main battery? What happens to the Lithium battery in a situation like this? I would appreciate any comments or suggestions on the subject. Thank you.

 

Welcome.
I've been using this with no issues for several years now on 2 cars.
A friend of mine runs ( 8 ) of them, some of his rides don't move for months @ a time..

I also run the battery tender brand maintainer on my vehicles for months at a time over winter. I would rather leave the battery connected on a maintainer rather than disconnect it.
