Lew,

What exactly did you mean by "our monitor"?

I just don't understand why AM Solar is monitoring at the pack level and not the individual cell level.

Elite sells a complete system too. But also offers the GBS batteries separately, the boards, and choices of controllers, etc to build a DYI system. Could be various applications beyond just RV use.

AM Solar is only selling complete systems with perhaps more emphasis on RVers.

AM Solar decided on their present lithium system after extensive real-world testing (18 months) of many varieties of lithium batteries from a wide variety of sources.

They are focused on the RV solar business and build and sell what works best for that specific environment.

Beyond that, only Greg Holder, pres. of AM Solar would have any more details.

What did you use for the relay? Seems like it's only connected to the undervoltage control. How much amperage does it draw?

lewster:

The relay in the photos on the amsolar website look roughly the same as what I have, but the images are not detailed enough to zoom in on, any chance to find out what brand the relay is?

I'll check it out when I get my next BMS unit…..which should be in a few days and let you know.

Lew, do you know if AMSolar is top or bottom balanced? Seems like bottom is better from my research, but top makes me feel safer about putting them in my airstream. Although a lot of EVers use bottom.

I believe it's top balance. I'll check for sure on Monday.

Lew,

Do you know if the Magnum BMK works ok with Lithium batteries? Over a year ago, Magnum told me not to use the BMK since they had never tested with Lithium and did not think the BMK would give an accurate SOC.

Also what does AMSolar provide to show cell voltages similar to the display from Elite mentioned in an earlier post that showed cell voltages?

AMSolar monitors at the 4 cell level, which is kind of a shame. And I can't tell from their pictures if their EMS(CPU) actually has a video out port. Doesn't look like it.

I was reading the Elite operations manual and realized that a shunt is involved. The results from the EMS CPU can be displayed on a LCD screen (ghaynes555 provided a picture earlier). Of interest is the current in and out of the batteries and a battery pack capacity.

So battery monitoring is there and there should be no need for Victron or Magnum battery monitoring.

Does the AMSolar system have a shunt? As BoldAdventure pointed out, their CPU may not have a video out port. Is a Victron or Magnum battery monitor needed with the approach that AMSolor took?

ghaynes755,

At post 18 your said there is a momentary switch that changes to the individual cell information.

I believe the switch is wired back to the CPU.

Your picture shows a TFT color monitor with buttons at the bottom. Is this what you received from Elite? The Elite website shows just the LCD monitor for $50.

Where exactly is the momentary switch in your pictures?

You can get the LCD for $24 on Amazon FYI

The rest of my supplies are showing up during next week. Started on my battery mounting today.

From what I can tell, AMSolar's kit is pretty basic. Including their CPU. You'll notice from Switz picture that you are getting 4 pack monitoring. I also see a lack of LVC and OVC.

You are not going to get individual cell monitoring from the Victron or the Magnum, but you will get overall battery bank monitoring.

Since I have a Magnum Hybrid I use the ME-RC control head which includes battery monitoring and lots of other functions.

The momentary push switch is mounted up next to my BluRay player. I seldom use it.

Monitor is from Elite ($50) and includes cabling and power connection in one cable from the monitor until it splits. Makes it pretty clean to install.

ghaynes755,

My confusion was that your picture looks like the TFT LCD monitor that BoldAdventure provided a link for. The Elite web site shows a plain LCD monitor with a cable only for power. Elite probably hasn't bothered to update their web site.

Also since you said you used the Magnum BMK, did the BMK and Elite both use the same shunt? Did you find the state of charge calculated by the BMK to roughly match the state of charge from the Elite monitor? If not, which one was more accurate.

The BMK is an option for Magnum inverter/chargers and only uses the ME-RC as a display device. Unless the Elite state of charge is not very accurate, then I do not see the need for a BMK. I must be missing something.
