AiLi Battery Tester: Accurately Measure DC Voltage up to 300V and 400A Amperage

Wolfgang Kadelka: nach dem Einbau lief alles ok. Die Gebrauchsanweisung ist allerdings nur auf englisch.

Anonymous 789: Works very well.
Sensor fits over a #2 wire lug and loom just fine. You just need to figure which direction it goes on the wire for the Amp Hours to count up or down correctly.
A small glitch when setting voltages with the more than one number flashing but not a big deal.

Andreas: Ser ut att mäta ström korrekt, även om spänningen tycks vara lite högre än vad ändra mätare visar.

Enkel att installera, men något korta och fjuttiga kablar som jag var tvungen att förlänga.

Något svår att ställa in på grund av den bristfälliga manualen. Krävdes lite googlande för att förstå hur man ställer in korrekt ampere och ställer in gränser för varningar.

Leonardo Magini: Ottimo monitor per batteria. Peccato che le istruzioni sono un po' scarne e scritte solo in inglese. Non è molto chiaro il settaggio di alcuni parametri.

Cliente Amazon: Me gustó la facilidad de instalación. No me gusta su resolución de 300mA para las corrientes bajas ni la calibración no acorde con los dígitos del manual.

Miamijerry: Voltage reading is dead on correct. Needs to be wired so charging shows as a negative number and discharging shows as positive number. I had to deep cycle the battery (Take it down to 10v with a 10 amp load) and then as it charged back up, the battery Icon and AH reads starting working correctly. Mine came with a long lead which was perfect to go from the battery, inside the car and across the dash. "Under Voltage" setting, sets the voltage at which the voltage number starts flashing. Great purchase.

W. Pollitz: I was waffling about buying the trimetric battery monitor and frankly had a hard time believing I could get the same information from a monitor that costs 1/5th the price. I'd have given it 5 stars except the cable to the hall effect transformer is about 5' long. Hardly enough to reach in most applications. a little doorbell wire will resolve that issue but for an extra $0.75 they could have easily included a longer cable.

The initial setup instructions are poorly translated but the setup is intuitive. Remember to save your settings after each step.

All in all, I'm quite pleased with the monitor, it's price and it's performance. I'd buy it again.

Benjamin J. Coleman: This is a very cool battery monitor. It comes with a one page instruction sheet. It's pretty easy to set up. In the settings, the maximum amp-hour you can set is 99.9, not 999.9 as the instructions indicate. Luckily it'll detect how big your battery is after you've completed the setup. You need to run your battery all the way down and then recharge it and it'll display how many AH are available.

I bought a 25 foot shielded, 6 wire twisted pair cable and was able to extend the cable that came with it by that much. It seems to work just fine after the extension.

Mike Kell: I ordered this for my 1993 Toyota Pickup I'm rebuilding. It works , however the mode change button is in the back of the unit and can't be accessed easily once it's installed. I would like to add a remote push button so I can change modes without having to disassemble the dash of my vehicle to get to the switch. I was hoping the instruction manual would show me where to wire the remote push button, however I didn't get a manual with it. So I'm giving it only three stars. If I'd gotten everything that is suppose to come with this I'd most likely have given it 5 stars. It does work well as best as I can tell. It's got a nice large easy to see display, but you can't really be sure what your getting as far as the mode it's in.

AJ: Extremely useful for monitoring winch and dual battery current flow on my truck. I'm not using the AH or capacity readings so I like the way the meter always powers-up to the previously selected display mode (V and A in my case) although the mode button is conveniently located on the meter's front panel anyway. I particularly appreciate the Hall effect sensor: no need to install a shut (which I would be concerned about burning out under large current spikes). Your application must allow you to thread your cable through the sensor torus since it doesn't "clam-shell" open, but the meter seems accurate when compared to my bench-top power supply. I don't know how stray magnetic fields might affect it--I don't see a calibration button--but for my purposes, it works great! Including a sensor cable extension would have been nice, but it's easy to splice one in. If the price were lower, I would purchase one for each of my vehicles.
