Good, basic battery monitor

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.

Good Meter for the Price

Please don't expect a $200 meter for $30. You will not have the accuracy of a $200 meter. With that in mind, this meter does work and the calibration ability makes it well worth the $30 versus the really cheap meters.
The voltage calibration worked well the first time, the amp calibration does take a couple of tries of setting the zero point, then the high current point to get the meter to track the current correctly. The instructions with the unit are not very good, you have to know a little about what you are doing so that you can read between the lines. No stand offs are provided for the connector board. You will need to buy some separately or use hot glue to make some, as I did.
Overall a good meterRead full review...

size meter correctly

Meter looks quite useful. Currently item has not been installed as it was not throughly thought through before purchase. Item was bought to monitor aux batt. Size of meter purchased was the 100 amp. It will work for draw from my inverter but not the higher amp draw from my winch. Be SURE to size your meter correctly to your install.Read full review...

Does a good job - easy to use

Prompt delivery. Found calibration instructions a bit unclear, but the supplier clarified. Clear display, easy to operate. Has now been working well for several months. Fantastic to have reliable measure of battery charge status.Read full review...

Works as advertised

This small monitor works great and is accurate once calibrated against a known device. I connected to a 12V deep cycle battery to test it. I followed the instructions to calibrate the voltage and amp draw display against a Fluke meter with a Genius charger connected, then a load device of 7A. This meter displayed everything correctly during load and charging. I used the Fluke VOM to get exact load/voltage info and calibrated the V and A per instructions. It worked great and was accurate. The display can be turned on/off by pressing the SET button quickly. This is a great device in my opinion.Read full review...

Excellent Value

This battery monitor was simple to install and performs all the necessary function to keep track of current in and out of my RV house battery and the voltage and percentage capacity.

Very accurate once set properly

Very simple setup ... hardest part was knowing how much load was applied to set amp draw... well worth the money ... directions clear and concise
