nope. never really had an issue with low water levels. I do check, but they rarely need topping up.

What causes level drop? overcharging/temperature/evaporation?

Charging the batteries causes water loss....when charging, the electrical current causes the water to return to it's original components...hydrogen and oxygen...this gassing will create water loss..

Maybe you need to check your charger. A few years ago I found my Guest 3 stage, 2 bank, charger was "stuck" on almost 16 volts. I'm on a mooring so I only used it when the boat was on the hard and even then only an hour or two when I was aboard. So I caught it b/4 harm was done. That's a bad failure mode for a charger.
I replaced the charger with a new Guest (now made in China) but I don't really use it any more. After topping off the batteries when winterizing the boat, I find they stay up all winter w/o any help from me. As to water, once a year is all mine need.

I have a 2" digital volt meter on my panel. Cost $13. on ebay w/ built-in LED light. And a 2 way momentary toggle switch. First and last things I do aboard check the battery voltages.
