This seems to be a well-built battery. It arrived in only a few days, unlike the month plus that Amazon estimated. Without outside security cameras, I never would have known it was delivered. No phone call, no doorbell ring. It was left in the driveway, and I would have hit it backing out of the garage. The unit charged up just fine with my 48-volt inverter charger. The thing is heavy! I needed to get help to lift the box up, but once the box was on its side, the unit rolled out without any issues. Rolling it on carpet requires more help. Getting it over a short door edge required help. According to the paperwork, it was 350 pounds. I'm glad to get so much energy storage in one unit. See the photos for how it was delivered.

I made the decision to power my home with solar after 3 years of research. Solar without a battery to store energy for later use did not make sense to me. The battery I chose is the AOUSK 48v 320ah 16.38kWh lifepo4 with a 200a BMS. On paper this battery looked impressive and met all my requirements including a separate breaker. The battery came well packaged and felt commercial-grade, sturdy, and well built. This cost effective battery is fantastic for reliable high energy output. Setup was easy and straightforward and works out of the box with my 12000W ANENJI split-phase inverter through the 486 pylon communication protocol. I had one issue with the setting on my inverter and AOUSK was willing to help to get their battery working in my application. Impressive after sale customer service! I have been monitoring this system for over a month now and have had no problems powering all the loads in my home including AC and electric dryer at night (AC spends quite a bit of energy cooling the home at night after it has been soaking in the sun all day). It has provided energy independence and peace of mind during power outages. I highly recommend the battery and am considering getting another AOUSK battery (in parallel 32.76kWh) to power loads during those cloudy storm weeks where solar underperforms and the battery may have to go days before being recharged.

This unit comes with a JBD BMS and no where on the description did the seller mentioned that. After purchase I realized it would not communicate with my existing batteries with a JK BMS. After contacting, seller they stalled until I requested to return the battery for them to take action to resolv. It's a good battery if you don't need communication with JK BMS, wish seller would state that important information in the description. The wifi connectivity is spotty, not reliable.

I purchased this 16.4kWh AOUSK unit to replace a bank of older lead-acid batteries, and the difference is night and day. First off, the build quality is impressive. The metal casing is rugged, and the integrated breakers are a huge safety plus. Nice thinking by their engineers. I am running this with a Victron MultiPlus-II. The RS485/CAN communication cable had to be modified but it worked immediately after selecting the correct protocol on the built-in LCD touchscreen. It’s great to see the BMS talking directly to the inverter for accurate SOC (State of Charge) monitoring. Performance: With 320Ah, I can run my entire house (including the AC) overnight and still have about 40-50% left in the morning. The 200A BMS is robust; I haven’t had any issues with high-surge loads. Pros: Integrated LCD screen makes checking cell voltages very easy. Grade A cells (the weight and capacity tests confirm this). Massive capacity in a relatively small footprint compared to 100Ah rack batteries. Cons: It is heavy (as expected for 16kWh), so have a friend help you move it! Overall, if you are looking for a 'Powerwall' style setup without the $10k price tag, this is a serious contender.

Very solid and easy to manage with the built-in handles. I like the way the top opens up for cable placement. (Tip i put painters tape over the communication ports just make sure no spiders or little critters got in them) Cables are super nice. Nicely boxed up,just take top and side where bottom of battery is, slid it out 5or so inches then it stands up easily on its own wheels. Go's over uneven concrete easily. Will buy another.

Only been using this for 1 day, but I can say that it has done thus far exactly what we expected. The company kept in touch with us made sure to delivery was carried out even from the distance of their original shipping location to a rural area here in the United States. Be aware that this battery weighs almost 300 lb so you will need assistance once it is delivered.
