Solar charging and battery monitoring question

I have been using solar panels for charging my camper batteries for a few years now.

I learn something new EVERY DAY!

Something I have recently learned was that the charger/converter that came in my camper may only keep my 2 6-volt batteries charged to only 70% and also may boil them dry in the process. YIKES!

Yesterday, I replaced my factory charger/converter with a "Smart" charger/converter.

Also, I am adding a portable solar panel, where is the best place for locating the charge controller? Closer to battery or closer to panel?

Although I have dry camped, once for a whole season (may - oct), I have always been insecure about knowing when the batteries where getting dangerously low.

Is there an affordable monitor available that I can install to give me the feedback I need?

Any other insights would also be appreciated.

Thanks

    So you have an LK 100 amper? You linked an old style PM on Amazon--not the same thing. Confusing.

    Here is the LK--internal fan, the two holes in the side, except this photo is the 55 amper with the two fuses. The 100 amper has four fuses.

    https://www.amazon.com/Powermax-PM3-100LK-Power-Supply-Light/dp/B01MS4F5QT

    Anyway, a heck of a price for a 100 amper with adjustable voltage-- Holy Cow! Plus you can switch it to the auto 3 stage and just leave it, if you want.

    Some PowerMax customers like car showroom folks, have asked them to just leave it as a 3 stage on delivery and tape over the holes! :)

    Too confusing it seems. :) Of course we RVers are way smarter than that, and can really appreciate just what this is!
