Looking for a weatherproof battery status gauge for my tent trailer

[Jevy]

Hey everyone,

I am in process of putting together a tent trailer m416a military trailer. I have a tongue box I'm going to mount on it with an optima battery inside for charging iPads, running 12v fans/accessories while camping. I was curious if anyone knows of a weatherproof gauge that I can mount on the outside of the tongue box to check the charge level left in the battery. Any info would be appreciated.

Saw this one the other day. It is made by NOCO Genius. They say it can be mounted on an ATV, so I'm guessing it's weatherproof.

I have used these on my last two trailers:

I don't recall their water resistance rating, but can attest to their survival mounted to the front of my trailers.

Available from Amazon $12 Elsewhere as low as $7

Clean install and you can see the status from a distance
