Hi everyone, Dave here
0:09
Today I have on my workbench a pair of these XZNY Ultra Mini 100 amp-a-lithemar and phosphate batteries
0:18
And they are rather small. I've picked up a lot of 100 amp-hour batteries and these do look small
0:26
So they've really crammed the batteries into this form factor here. and I'm going to do a discharge test on these to make sure they really do have 100 ampires in them
0:35
I've got two of them, so it's going to be 200 ampers. On the back, it says service at xC and yBattery.com and three-year free replacement, so that's good
0:43
The bolts are M8, so obviously these can handle some current, and that's a good thing
0:48
My plan is to test these batteries thoroughly, including a deep cycle test
0:52
I'm going to put these batteries both in parallel to make sure they really have 100 ampires in them
0:56
So I'm going to add them together, and I'm going to see if I have 200 ampires of storage. Let take a look at the mini 12 volt 100 amp power battery product page You can see here they have some promotions going and the product dimensions are 5 inches by 9 by 8 And interestingly if you calculate the cubic displacement of this battery
1:22
you can do that by multiplying these numbers. On the left, you have the mini 12-1-100 ampire battery
1:29
On the right, that's another battery that's on the market. I guess it would be a competitor
1:33
And you can see that the difference is about 28%. So here I'm going to calculate the percentage as well
1:38
and you can see it's 72% of the size of one of the competing batteries on the market
1:45
So they're telling the truth when they say it is smaller. It is a mini battery. It is physically smaller than other batteries that I have tested
1:52
And the question is, does it really have 100 ampower? In order to do that, we need to do a complete discharge test
1:57
which I will show the results of in this video. So here's the thought. XE and Y's compact batteries have a higher price
2:04
but they take up significantly less space. What's the most important? or compact size. This battery has a 100 amp BMS and it does have low temperature
2:14
protection. That means that if it gets below freezing it should turn the
2:18
battery off and not allow you to charge it. So that's good. As you can see they're
2:23
targeting RV off trolling motors things like that which is relevant and makes sense Okay let move on with a test
2:36
XZ and Y actually states that they'd welcome you to test the battery capacity, and that's very impressive to me. So anyway, let's give it a go. Here's the bench test setup
2:45
I'm using a 1200 watt Pyrsign inverter, an MPPT charge controller, and an air conditioner
2:50
Capacity will be tracked using this coolum counting battery meter, which logs how many amp hours are flowing in
2:54
we're out of the system. Okay I'm ready for the bench test. The battery has been sitting
2:59
here fully charged for a while. I've got my 5,000 B2 air conditioner plugged into this
3:04
power strip. Let's turn on the inverter. Let's turn on the inverter
3:24
see okay okay the bench Okay, the bench test has just started, and I'll be right back with the results
4:10
Each of these batteries has a little bit more than 100 ampires in them
4:14
They did not have any problem during the test. They cycled just fine
4:18
I don't have any complaints there. And it's good to know they have the rated capacity as advertised
4:28
These 100 ampire X, E and Y batteries have been integrated into my off-grade solar power system in the solar workshop for some time now
4:37
They've been through multiple cycles and real-world scenarios. powering a desktop computer, a 5,000 B2 air conditioner, and various other appliances and devices
4:46
They have the advertised capacity and have not given me any problems at all
4:50
Therefore, I can recommend them. Please note that I don't accept sales commissions for product reviews
