I have not had the opportunity to use the battery yet !

I have not had the opportunity to use the battery yet !! From what i can tell it seems to be a great quality battery . The experience with the order and shipping was good !!! I actually plan on ordering another in a week if the sale price is still on. I can only buy parts for my system as i can afford them so its a piece meal event !!!

Product is as advertised

Product is as advertised. I’ve only self checked the batteries for now as I building complete 8KW off grid system and not done yet.

Been working great

Been working great. I have 2 and plan on getting 2 more

Great

Been working great

High quality and great service

I a. Impressed with these batteries. Great quality. And the company is amazing. Customer support is responsive and accommodating. Highly recommend. I will build out my entire battery bank with these.

Good build

I purchased two batteries,,the package is good the only thing is the terminal short out my battery . The wire groundout on the 4 screw that hold the terminal down

I am really impressed with the quality of the Humsienk 48v 100Ah 3UServer Rack Battery

I am really impressed with the quality of the Humsienk 48v 100Ah 3UServer Rack Battery.
I have installed it on a Dolly or Hand Truck. I also posted a video on my Youtube channel. http://www.youtube.com/@RednekGeeks

I have only been workingthis battery for a few days

I have only been workingthis battery for a few days. Seems to work as advertised. Packaging was good and it arrived quickly in fine condition. My only complaint
Is that the included wires were a bit on the short side.
I plan on expanding my system and will be ordering more soon.

Works great with my xw pro 6848 inverter charger

Very nice quality

Very nice quality, wish had a few more, nice price, fixed income trying to lower electric bill

Batteries work well but....

So far the batteries have been holding up. My house has been off the grid for a few weeks now. I bought 2 batteries that are connected in parallel now. However, I noticed that the voltage vs state of charge doesn't match up for both batteries.
Explanation: Battery A is at 94% with a voltage of 53V and battery B is at 84% with a voltage of 53V. So the voltages of the batteries are normally close but the battery percentage is different. I am not sure if that will eventually cause any issues

Great value for the price

Overall, I'm impressed with the build quality/value when compared with other server rack batteries. There are a few things that can be improved, but it integrates well with my other batteries. The raised screw heads on the terminals should be re-designed so that they are recessed, and can't be inadvertently contacted, potentially causing a short.

On my initial charge, the cell voltages differed by over 200mv at the top. I did a capacity test from the initial charge & got 100.365 ah, but I had it set to cut off at 44.5v, instead of letting the BMS take it out. On the subsequent charge, cell differential was over 250mv at the top. I let it sit overnight, so the active balancer had some time to work. Next morning I took the cells up to 3.6v+ with a bench power supply set at around .25a. All cells were within 6mv, which is impressive.

I've ditched the factory app for monitoring in favor of the TDT "BMS meta" app, which allows control of more of the battery parameters.

At this price point, it's a winner - just change those screw heads on the terminals!

Good working

Great value!!

Love this battery great value!! Will be adding more of these to my system soon!!

Buenas baterias

Good controls

Good controls, good bluetooth. Storeslots of energy. The app allows you to change the low voltage cutoff, which is great.

Muy satisfecho con la entrega y el producto recomendado un 100%

Quick shipping

I'm impressed with this battery!

The only reason for 4 stars is that the unit arrived dented in the top cover. It looks like at fedex something poked through the box and dented the top cover. There was no internal damage to the battery. I popped off the cover and banged the dent out of it. You can't even tell that it had a dent. While I had the cover off, I looked inside the unit and it is very well made.
