Lithium battery upgrade issues? 2021 zinger trailer

[blackforest]

Hi

I have a 2021 crossroads zinger zr18rk

I am thinking of upgrading to a 100 ah self heating renogy brand battery. (drop in one battery)

I am wondering if anyone had some issues and thoughts doing the upgrade without any other modifications.

I am aware that the existing power management system will only charge to abut 80% which is no issue for me, since I have a renogy solar panel with controller with lithium option that will be connected straight to the battery terminal when parked.

And by getting a battery with self heating I can charge in colder weather

Third issue I am aware of is that I can't use the charge level checker in the trailer, I will get a blue tooth plug in to see the charge percentage on my phone

Thanks

Chris
