Great product

I’m a mobile dj, and only use accu, without 220V power.

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.

I had good customer service, the battery shipping was good an packaged well the quality of battery appears very nice you can see the inspection video https://youtu.be/an6IC2EYY5I you can see my unboxing video https://youtu.be/U3Onl1TdDKE and watch for future update videos

over all I am really happy with both the company customer service and the battery's I recived

The only issue I have had is the battery cables are not included to connect battery to battery

Communication wasn't the best to start but improved rapidly. Truck delivery couldn't have been better and the driver was great.

My batteries were packed incredibly well. I only have one crate that was damaged but the battery was not touched and seems fine so far. I ordered 4.

I purchased the 14.6V/20A charger to charge my Humsienk 150ah smart battery. Within a few minutes of using the charger it started to smoke.
I unplugged it and emailed customer service to let them know I had a problem with it. They wasted no time in sending me a new one. Once I received it I tested it out and it works perfectly. It charges fast and efficiently. I couldn’t be happier with my purchases from Humsienk! I’ll definitely be buying other products from them.
Thank you Humsienk

I purchased the 150ah battery to run 2 diesel heaters for ice fishing. This size worked out perfectly, I didn’t need to carry multiple batteries with me. The Bluetooth on it makes it all worth it. You can see how many amp hours the heaters are using and plan around it. I didn’t know what expect because the price was so good. I couldn’t be more satisfied.

Absolutely awesome good build quality arrived. Perfect, sealed connections beyond the call of duty. Charge and discharge.Flawlessly every day could not be happier.

Everything seems to be working as it should lots of power should last me about 4 days without Sun

I purchased 8 49 volt rack batteries stackem up plug in and I have tons power . service has been very good .I will buy 8 more there great 👍

I recently installed four Humsieng 48 V 150 Ah lithium batteries (configured as a 48 V, 600 Ah bank) to pair with my EG4 12000XP V2 inverter, and the performance has been outstanding. These batteries deliver stable voltage, strong discharge capability, and excellent runtime under real household loads.
Electrical Performance
• Nominal capacity: 150 Ah per battery (600 Ah total in parallel)
• Usable energy: ~28.8 kWh total at 48 V
• Voltage stability: Holds voltage extremely well under load, with minimal sag even during high‑demand events
• Charge acceptance: Smooth charging curve with predictable behavior when manually setting charge parameters on the EG4 inverter
• Peak discharge: Easily supports whole‑home loads through the 12000XP V2 without any instability

The battery is good value the money. The capacity, cables, and form factor are all great. The Bluetooth app works well and I was able to communicate with EG4 6000XP (capacity and SOC) using the inverter's lithium battery setting 2.

I had two issues with my batteries. First the packing material were insufficient to protect the battery during shipping. The steel case appears to be a bit thin for the weight of the battery and a couple of corners had some damage and the front panel of one of my two batteries also had dimples in the steel from light damage.

Another issue I experienced with both batteries was related to low temperature discharge cut off. There are two low temperature cut off settings, one for charging and the other for discharging. The low temperature cut off for charging works correct, but the low temperature cut off for discharge does not. When the battery temperature falls below the charge cut off set point, the battery also also disables discharge (despite a lower discharge cutoff set point). This effectively means you can't discharge these batteries below freezing.

I was able to overcome the low temperature discharge cut off issue by building a small insulated enclosure and added some greenhouse heating pads to keep the batteries warm enough to charge and discharge.

Although there wasn't a firmware patch to fix the low temperature discharge cutoff, communication with Humsiemk customer service was pretty good. They were responsive and made a genuine effort to achieve a satisfactory outcome.

I was bit skeptical at first because I never heard of the brad before but I went ahead and ordered a 2 pack of the 320Ah batteries because they had a presale and got a good deal, unfortunately they were lost at delivery due to FedEx not following delivery instructions and after reading some of the reviews about lost packages from FedEx I think Humsienk should not use their services, UPS could be a better option, however, I did added shipping protection with my purchase. I contacted costumer service to let them know about the situation and Arrow was very responsive and arranged for a replacement package, I got them after few days and my first impression was how well packaged the batteries were, I did a quick test after a couple of days to check the state of charge and they both showed 13.19, 13.20 volts. Batteries seem well made and solid and so far they are working great. I give 5 stars to Arrow from costumer service and to the product quality.
