Good, basic battery monitor
1 of 1 found this helpful I have just installed this, so I don't have any long term experience with it. The instructions were straight forward to follow. I checked the accuracy with an HP lab grade DVM and it was spot on for voltage. I used a clamp-on DC ammeter to check current with a battery load tester. The current required a small correction. The amp zero would only get to about 1/3 A, no doubt an issue with the very low voltage on the current shunt.
Installation requires cutting a battery cable and attaching large gauge ring terminals (not included). I used vice grips to crimp the lugs, and a large wattage soldering iron. This had to be done in a confined space, so Youtube videos showing a propane torch is down-right dangerous. The display is not designed to snap into the thin plywood wall in my RV, so I had to hot glue it into place.
I spent 5-6 hours, not counting a trip to the hardware store. I could do it in half the time if I had to do it again, which ain't happening. But this is a good estimate if you took it to an RV shop. You will need hookup wire, battery cable ring terminals, heavy duty soldering iron, solder, solder paste, wood screws, and a hot glue gun for this job.

Effective immersion heater
This heater is quite effective; I measured the current at 10 amp at 12 V. That is 120 W. It doesn't take very long to get a liquid boiling. It has a clip so you can hook it to the rim of your cup. You don't want to fully immerse the plastic part into the liquid (it starts boiling inside the housing and leaves a bad taste). I have used it for about a month without problems.
