This multifunctional battery meter provides information about the following Battery voltage, discharge current, discharge power, discharge impedance, internal resistance, capacity, state of charge, energy, running time, and more
This product is ideal for solar charge controllers, inverters, automobiles, RV, vans, truck campers, as well as boats and other watercraft
A maximum of 300A at 0-200 volts DC

Questions & Answers

Does it have the ability to measure ?

What if the meter reads milli volts across the fixed resistance of the shunt and the meter would be able to distinguish between a positive or negative milli volt reading representing a DC current flowing Are you able to get an answer from Spartan?

How can I switch the current up to 200A with a different shunt?

shunt included with the meter is rated for 100A that is why the meter can handle a maximum current of

Can the rail be mounted to the din rail?

No, this battery monitor was designed to function as a flush mount meter. If you don't care about aesthetics, you could use zip ties instead.

Selected User Reviews For Spartan Power DC Meter Battery Monitor & Multimeter 0-300A 0-200VDC LCD Display Comes with 300A Current Shunt and Wiring Kit

It JUST WORKS once the screen is ON, but you must keep track of it at all times
3/5

There is a section in the PDF manual that I should have read before purchasing the item. "Normal" and "dormant" are the two modes of the 6 states. The screen is considered normal when lit up, while the screen is seen as dormant when it is off. When an item is dormant or has its screen off, it WILL NOT keep track of its energy use. It MUST ALWAYS have its screen turned on in order to retain its record. I reached out to them before I understood what was going on. It was said that "it was wired incorrectly" by the seller. There are no incorrect wirings in the module, and the pdf manual 2 indicates the system is functioning correctly. This item has an attachment 6 that is attached to this item. In summary (and also this review) although the item works quite well, the rating is lowered due to the amount of power that has to be used to keep the item working (both tracking and the bright backlight requiring constant operation). I don't like ones that add usage since we need to track every little bit of power used, so I'm sure everyone with one of these uses one because we need to keep track of every little bit of electric usage. While I acknowledge the need for power to keep the system working, it cannot be turned off 24/7 so that the usage can be traced. If you leave the screen on and check on it occasionally, you cannot connect to it and turn the screen off. You would still find that it is at the same location as it was last time you checked, the runtime would also be essentially the same as it was yesterday, and the power usage would be the same. In sum, I would just like to let everyone know what to expect. It will work, but at the cost of precious energy.

For $20, this is a great deal
4/5

Setting up the unit was a little confusing, but the support team was able to help me. That was amazing - thanks a lot We have an AMERICAN SUPPORT PERSON on the other end of it. The baby was terrific, although I had to hold him for a few minutes. During the setup process, he made sure I was looking at the correct options and spent time supporting me. I was pleased with the performance of the unit. I can see the draw of amps and watts on my AGM battery, and with a % meter at the middle of the screen, it shows the current voltage as well.

You can view all the geek stats you want on this device
5/5

This is a very nice Install it in no time. Is a tool that tells me how much electricity the battery is drawing when the power supply is less than adequate. This feature also tells me how much my battery is charging when it is I can't speak to how accurate an AH reading is, but measuring across a 100amp shunt shows that amps and volts are very accurate. Even if no one else cares about the stats except you, this is worth this price just for the cool blue display of them.

Despite the claims of what it can do, perhaps it's best to use a shunt housing instead
4/5

In short, it does exactly what it says. You need to mount the shunt where you want it. The solar system I installed on my travel trailer was built with this product. In front of the battery is the battery. It's essential to install this in front of the house since there's no cover and I want to It was something like this that I came up with. drilled into the trailer's frame with PVC conduct (self-made Screws and nuts, nut and bolt)
Electrical mastic tapes to cover screw/bolt (so that it does not touch the shunt)

The shunt is about 4" long. The width of 1/2 inch.

You just have to visit the local hardware store and get things looking this way There's no way I believe I got a 5x5 seal compound, a 5x5 conduit body, and it looks like a thicker version of play-doh This is what happened to me (the line must be sealed the person in charge at the hardware store for assistance (Electronic salesperson). The extra parts I bought cost me about $10.

I am complete when I am with you! There is no better way to end the day
5/5

This was the box I bought & the book In addition to that there is a digital meter to see current voltage and use of power. More to say will not be said. The results were better and we saved about $400.

Even in bright sunshine, the content is clearly legible
5/5

A box would have been nice to mount it in if it was available for optional installation in a golf cart. Using this method, I am able to efficiently determine what time is best to recharge my device. There was an overcharge from my battery charger that needs to be corrected. In the end, it is worth the expense, and will certainly increase the battery life of your smart phone.

A good DC current meter can measure current up to 100 amps
5/5

I was wrong when I slammed this. The shunt was not working properly, but now it is. I fixed it and everything works as it should. The power plus amp draw appeals to me a lot. The power consumption and amp reading will save you lots of time, and by knowing if your work is good or bad, you'll know if it's worth continuing.

Meter that works well and is very functional
5/5

On my modified electric scooter, I use this meter. The application is very functional and has a great deal of features. It also displays all the pertinent information With the supplier current shunt, it permits the user to actually see how much current is flowing into the batteries during charging. In most cases, those who reviewed the shunt and determined it did not work must have not hooked it up properly.
