P1000 Battery tender’s for dual battery settup?

My Question,
Installing a dual battery and isolater as seen here. No stinger, fuse block, or switch panel.
Do I need (2) battery tenders, or will one charge both when parked in storage?
Thanks!

Only need one. Hook it to the main battery.

I’ve left my P1k5 in the garage for over a month without starting and it does fine without a trickle charger. Of course this in in AZ during the hottest months of summer. My battery volt meter never shows much less than 11 volts and both batteries show over 14 volts by the time I’m out of the garage
