PowerUrus 12v 100ah batteries

[Jbarnes1719]

I purchased two PowerUrus 12v 100ah batteries after watching Will’s review of their batteries. One charged without a hitch. The other said it was charged 100% but flips back and forth between 74% and 100% every minute or so using the Roy pow app. The cells are balenced within .002 of one another. I have been waiting on the Victron 500a shunt I ordered to test it further. With return time as a consideration I have decided to return the battery to the seller unfortunately at my expense. We will see if the the replacement is better.

Sorry to hear your troubles. I ordered one 200ah battery and the battery itself has faired okay for me. The AH on the app has shown between 201-4 on my battery. However I am having issues understanding some undocumented features of the app and have asked for support which I have received none. I want to integrate it into a Home Assistant system that I have not even started and I want to know it is possible before my return window is up. As a matter of fact I think I will create a post here to see if anyone has done such....

Vendor has been good about it and immediately sent a new battery. I haven’t charged it yet so I will update as I do.

New battery seems to have the same problem but less frequent. So I finally got my Victron shunt so I could discharge test the battery. With approximately a 20 amp load, the battery gave 100ah's over a 5-hour period. The battery continued giving 23 amps with 0% power left for about 10 minutes. Very impressed so far. I would call this battery good but with a glitch of some sort. Imho, I believe there is a glitch with the BMS or the Roy Pow app. I wish PoweruRus had their own app. Nevertheless, PoweruRus is sending another replacement. I will thoroughly test this battery before coming to any conclusions this time. I will update with more info after testing the replacement battery. I recommend this company. They back their products. I appreciate good service which seems to be lacking with most companies these days.

Its been about 10 days. What is the latest info?

Also curious how it turned out. it seems all the test above except 1 are showing slightly below 100ah capacity something I've seen with other reviews rather consistently. But don't recall that coming up with Will's review. Really liking the bluetooth connectivity feature as I'll be using on trolling motor. Thus very tempted to grab one just trying to decide if I should get a heated one. Though chances of me using it in winter on boat are slim.

Lets see if Jbarnes1719 writes back as he never responded on my update request. As for me, my 200AH battery has done well. My app still shows 100% SOC and an actual capacity of 201AH. I have seen that powerurus did release some new batteries on their website. I am still trying to figure out how to get the battery SOC into my Home Assistant program via bluetooth.

I'm just putting my Powerurus 12V 100AH battery into play and it appears to working well with a notable exception. Once charged, full charge protection takes place and the charge mos shows off. At 83% attached to a Victron 75|15 with Lifpo4 presets, charger shows float at 13.5V (battery shows 13.2V, still with charging mos off). All this while powering a 12v car fridge.

I attached an Ecoflow Delta Mini at 80% via XT60 connector, charge mos turned on, Victron in now charging the battery in bulk mode, while the battery is charging the Ecoflow (which is why I got the battery in the first place)

New to all this, I expected the Victron to start charging/top off the battery when solar started hitting the panels, and not have to attach a device for the battery to start charging. I suppose I can get it all to work, just curious about the how's and why's.

Any better settings for the battery in the Victron controller?

Also, anyone know the verification number to get into the user mode of the app?

All the batteries have charged fully and correctly according to my Victron shunt. I believe there are some comm errors with the Roy Pow app and the Batteries. I am very happy with the batteries they have worked as advertised. My only advice is that even though they are rated at 50a charge I have only charged mine at 30a and have 100a+ discharge cycles. These are in my Fifth Wheel so they don’t get discharged daily as some other applications might. So I have only discharged these three times so far. These are keepers. I am sorry for taking so long to get back. I have many family issues as of late. I will try to check more often now. And yes I would buy more if I needed them.

 

[Jbarnes1719]

At this time I have not installed my solar charger and panels in my fifth wheel. I have used my Aims 75amp to bulk charge and the 0-30v 0-10amp power supply to balance/top the cells off. I am using the same set up Will uses in his many battery video’s. If I don’t have shore power I use my Yamaha generator.

 

[Jbarnes1719]

All of three batteries discharged a little over their rated amperage. So I am not sure about the accuracy of the Roy Pow app although I still use it to monitor the charge/dischage status of the batteries and while their installed in my fifth wheel. The Victron shunt is an option as a backup for accuracy. The app and the shunt differ a couple of hundred millivolts and as much as 900 milliamps but it is close enough for government work. I still see a flash of 74ah on the health at times but the Victron says 100ah and they have discharged over 100ah. (101-104ah)

During Will’s video he stated that app had no parameter change’s available. You get what you get. Not the best app but some don’t have an app at all. It is useful if you can figure out all the features.

All the batteries discharged fully despite what the app said. If you want an absolute accurate read on the battery I suggest using the Victron shunt.

Jbarnes1719 thanks for update. I have considered a Victron shunt, but have not jumped for one yet. I keep saying I would figure out how to connect to the bluetooth to get a SOC so I could have Home Assistant make a decisions on whether to charge the battery. But as I purchased the 200amp battery, mine has an easy life. I have pulled 136amps out of it for a few minutes while testing my inverter. But typically it powers lights, internet, cameras, etc. If the SOC was more critical to me, I would probably purchase the Victron shunt or figure out the bluetooth hack. But so far I have connected to the battery on my own, but have not figured out all the values yet. (If anyone knows please share)

I do agree with your thoughts on the app not being super accurate. I personally hate that the app shows a negative number for total amps whether it is charging or discharging.

Update on my 200amp Powerurus battery: At around 5 months of use, mine shows 35 cycles, 100 SOC and typically 200AH, though the app has blinked recently and showed 205 for a second before changing. It has been a quality battery for me. Customer service was not responsive, except through Amazon.

I just saw a thread a on using the Victron shunt for connection to Home assistant.

Where did they make you send the old battery to?

Did you ever figure this part out? I'm also planning on having the battery just connected to a victron solar controller and need to know that it will charge to 100%

It hasn't been a problem. Once charged to 100%, the app will show a "full charge protection mode" in the warning section. I took as a warning but it's more of a notice.

I really haven't fully used the battery. I have a long road trip planned staring in May but until then have only used it on occasion running a car fridge. It appears to run the car fridge a lot more efficiently than the Delta Mini that I used in the past and will still use for phones, tablets, 12v TV and other devices. The Victron smart controller (75|15) does a great job of charging it back up the next day with 200w of roof panels, mounted flat, even on overcast or cloudy days.

The battery sits behind the board. In the photo, the car fridge is plugged into the Ecoflow but I've recently moved it to the barrel plug on the board with an adapter. I can also use the Powerurus to top off the EF with the XT60 connector, but I also have a 160w portable panel, or can use the rooftop panels (to the right of the solar disconnect are MC4 connectors).

Recently according to the app, charge MOS was off, full charge protection on and at 68% I emailed support to explain, the reply:

"Because the battery has not yet reached the overcharge recovery stage, it is not allowed to charge. This is designed to avoid repeated charging of the battery. Charging will resume only when the voltage is close to falling below 3.3V. Please charge the battery again when the voltage is close to 3.3V."

The next day I checked the app, voltage had dropped, charge MOS was on and allowed to charge to 100%. I expected the battery to charge continuously to 100%, but at this time I'm OK with the behavior.

I may drop the Victron LifePO4 preset from 14.2v to 14v and see what happens.
