Paired with an EG4 6000XP this battery has worked very well for my first solar setup although I'm waiting to be able to purchase the larger 314aH battery to run a heater in a garage.
The battery arrived promply, however, there was a top corner that was severly dented making it completely useless for outdoor use. My only other complaint is the low temperature charge temperature. These cold days in Pennsylvania make it impossible to charge in an unheated garage, but I was aware of the lack of self-heating prior to the purchase.
Overall happy with this 100ah battery as communication with my inverter was flawless!
Purchased this 12 volt 150 AH battery to replace the stock lead acid which came in our RV. Has maintained the 12 volt system, which includes running the 12 volt refrigerator, for our camping trips. Has performed flawlessly.
May consider adding an additional battery in the near future to ensure compatibility.
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.
Received my 48 volt battery last week and have started my solar installation in our RV. Have charged and tested battery output with no issues. Look forward to being able to boondock in our RV.
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.
