150A RC Watt Meter Analyzer High Precision with Backlight Digital LCD Screen for voltage (V) current (A) Power (W) Charge(Ah) and Energy (Wh) Measurement (150A) -DC 0-60V Volt Amp Wattage Checker

This is a great battery monitor that let's you watch the condition of your battery. Add power pole connectors and it is awesome

i USE THIS ON HAM RADIO OPERATIONS TO MONITOR HOW MUCH CURRENT I HAVE PULLED FROM MY LITHIUM ION BATTERY WHEN OPERATING PORTABLE IN THE FIELD. IT WORKS GREAT.

The display is rather clear and bright. Love that I now know exactly how much power I'm drawing! Price and shipping time was unbeatable!

Advertised to show peaks but does not. It shows something under Ap and Wp but it's not right. On a 45 amp live pull, it shows the Ap as 0.5??? Same thing with Wp-not even close. It also shows watt-hours and amp-hours also, but thats not useful on a motor draw test to me (if it is accurite-I don't know). I tried to multiply readings x60 and other math but could not come up with any useful data from those numbers.

Meter works fine.A parameter not mentioned in the provided specifications is that the unit consumes about 20 mA when displaying. This information might be useful for some users.An option for smaller wire size with lower Max current capability would be ideal.

Love this keeps super track of my battery wish I had got 2

Meter seems to be accurate when it’s up and running but it’s very annoying to have to disconnect and reconnect it each time because the screen is frozen. This might not be an issue if you aren’t using it with solar panels, but I would guess the majority of people are using it similarly. I haven’t decided if I going to return it or not. I’m still testing and I will update this review if it quits altogether.

I'm using it on my solar panels to gather data.
