CAMWAY Battery Monitor 8-120V 0-350A Waterproof Backlit Volt Amp Meter, Precision Voltage Current Tester for RV, Car, Boat, Motorhome, Golf Cart, Caravan & Marine Vehicles

The shunt and monitor does what is expected. Unlike the Ali version on youtube, it does not come with a perspex case to mount it to a panel. I got around this with two L-shaped brackets and a tube of Araldite!The Main posts are M10 size but my M10 lugs didn't fit them so you may need to get bigger lugs for the cables.the display is made to fit into panels, so once again you'll have to get creative if you don't want to cut a large hole into wherever you wish to mount it. Lastly, the cable that connects the display to the shunt is in two parts and is very long which is a good/bad thing depending on your requirements.I'm using it with two LifePo 20Ah batteries in series which have an internal BMS but so far it has worked OK and indicates how much life I've got left. It's interesting to see how the battery depletes overnight.Instructions are OK but a bit quirky in parts.

This is a great little battery monitor and works just as well as the more expensive competition. Once it's calibrated correctly it works great 👍

My only gripe, is that the crimp on connectors provided in the kit, did not fit the bolts of the shunt. Other than that, this works perfectly and, apart from the connectors, installed easily.

The unit was easy to install, very simple to setup. It gives a clear readout of what is happening with the battery’s when charging or discharging. Love this unit.

Can't review this as the display meter was faulty. Did the whole wiring as per the instructions and found that the meter was dead. No display! What a waste of my time. Amazon refunded me promptly on returning the item.

Yes

Everything works very well, is accurate but it has a very short cable to the display.

This has been a very easy device to add to my battery build. The instructions were readable (some people said it was an awfully translated English; I didn't find this the case at all), the display gives a very good detail on what your SOC is at, the terminals are absolutely huge! I had to find the 17" impact socket I use for my vehicle's lug nuts. I'm very confident those cables aren't moving anywhere.One thing to note is the battery wire going to the shunt; you can use either slots on the green connector, but we needed to wiggle the soldered end quite a bit for it to actually fit inside. I'm guessing a little too much solder was used on this cable, but it will go in and it also maintains a tight securement. I would also recommend to not bend that wire either, as it looks easy to break the soldered piece off. If this happens, strip a little bit of shielding off the wire and re-solder the tip. You should be good to go after that. But other than that, this monitor is surprisingly excellent!

Après avoir configuré l'écran en indiquant le % de la batterie les indications de charge par le solaire ou l'alternateur sont fiable mais mise a zero dés l'utilisation de chauffage ou du frigo. L'ecran affiche alors zero et plus rien n'est fiable.Inutile pour son usage...

Mach einen guten Eindruck, ich konnte damit meine 200A Batterie prüfen, ob die Leistung auch stimmt, ich würde aber das nächste mal ein gerät nehmen, das gleichzeitig Strom und Spannung anzeigen kann. Aber für einen schnellen Blick auf die Batterie super geeignet.

At one fifth the price of the Victron I think this will likely do a reasonable job. I did an accuracy test as the photo shows. What you have there is a Fluke meter showing a 5.13 amp load, while this meter is measuring that same load and shows a 5.126 amp load. For the test, this was all hooked up to a Duracell AGM running a 55 watt car headlight. I was impressed with the results. The volts came in also well under a 1% difference between the Fluke and this meter.What I don't know is how well it will track the battery SOC over time, that's a math equation using time, voltage, and current. We shall see. To start, I was most concerned about the unit measuring the current properly, and it seems to do that well.I also measured the idle current consumed by the unit itself. That consumed current is not included in the reported battery SOC. While in standby (0 amps through the shunt) the unit appears to be waking up at a 1 hertz rate to sample the current. Because of that sampling, the idle current bounces from between 1ma to what I'm guessing to be about 7ma. Just use 5ma for an average number. So at rest, this unit will consume .005 x 24 = 0.12 amp/hours per day from your battery. Since my system will be on solar this is not a concern. Well that's what I know so far...Update. So I went and bought the Victron BMV-712 for $210 to compare this unit up against. Guess what? I actually like this one better. Yeah the Victron has a bluetooth link to your phone, but honestly that's a bit of a novelty. Once you get used to your loads and battery performance, you know generally where your numbers are. It's not so hard to go look at the display. And on that note, I find the display of this unit far more pleasing that the Victron.Anyway, I was concerned about accuracy of this unit. I have a CBA IV battery capacity tester calibrated to much better than 1%. During 20 hour capacity tests (which are really neat by the way) this unit tracked almost dead nuts to the CBA battery analyzer during the duration of the test. Meanwhile the Victron didn't do as well. To give you an example the test on a 100 Ah battery was pulling 5 amps. The CBA read 4.959 amps, this unit measures 4.977 amps. And the Victron measures 4.89 amps. It always read low. And then on to consumed amp hours, a spot check during the test showed the CBA IV says 21.93, this unit says 21.95, and the victron says 21.3.Bottom line for me is this is a great unit. What I don't know is did I get lucky and get one that was spot on with the calibration. I am going to order another one and find out! For now I can say don't waste your money on the Victron - they ain't worth it!
