    I ordered 12 of their 48V server rack batteries in two orders of 6 each. They were received as and when promised. They were packed well (on pallets) and arrived with no damage.

    The support staff has been available to answer my questions promptly via email and provided support and warranty replacements for a couple of under preforming cells.

    They have a high quality build which is why I purchased them in the first place and excellent price and continue to make improvements in this product. The built in screen saves you thousands on unneeded monitoring equipment because you can check each battery’s SOC, rate of charge or discharge, individual cell voltage and the temperature sensors and more all from the screen built on each battery.

    My power wall build is still in process and consists of two banks totaling 60 kWh I have 50 kWh just over 1000 Amps already installed and it has worked like a charm for almost 60 days of completely cycling them every 24 hours. Attached is a pic of the system so far but it is still a work in progress. I plan to make updates.

    Battery 🔋 arrived safe and on time. Packing was great. They are heavy, have a friend or two to help, have your space ready.
    Unit
    Mine have a 104.3 ah and a 103.6 ah, the cops between the two works well, pc interface is monitor only as far as I can tell.
    I have mine hooked up to a EG4-6500 ex. The BMS communication to the inverter works but has shut the inverter off twice in 5 days, went back to user and will wait and see. The batteries stop charging when they hit thier Ah max(varies by battery????). Screen and inputs for on battery is good buttons have a firm click. I think the screen would be better if moved to center of unit, as cables will be in the way of your screen.

    Battery is working out great, and the screen comes in handy. I was able to pick the battery up right form the warehouse, easy peasy.

    I ordered qty 10 of the 4U | JK48V100PRO 51.2V 100Ah Server Rack LiFePO4 Battery’s. They arrived in a large plywood crate and were in perfect condition, well packed. The sales team and support team were very responsive and informative when I had a few questions. They came with good quality cables and each battery had a separate test sheet inside each box. They came with about a 60% charge and I used the 48V charger to top off each one before initial hookup. Took about 2 days to get them all up to full charge individually. The terminal connections are very solid and hold the cables well. I also purchased two of the 4U / 5U racks and they were also very good quality. After pulling out my 24 2v Rolls Surrette bank I quickly had these hooked into my system and up and running. I have a 14KW solar array broken into three legs that run into 3 Midnite Classic 150s that charge these batteries. These batteries tie into 3 MagnaSine Inverter Converters giving me about 120 A/C Amps to power a 100 amp service into my home. They charge quickly, have minimal heat output and are much cleaner than the lead acid’s I had before. Only maint I need to do is dust them off once in a while. BMS is easy to work with and the system looks good next to my other setups.
