Today, the Humsienk 51.2V 100Ah LiFePO4 battery comes to the workshop, a compact energy storage device with a capacity of approximately 5.12 kWh, equipped with BYD cells.

I'm testing it exactly the way I like it best – not just examining the housing, but also looking inside, checking the cells, the BMS, communication with the inverter, capacity, and how the battery behaves under heavy loads.

🔋 WHAT DO WE CHECK?

✅ Actual storage capacity
✅ BYD cells and their production dates
✅ Internal build quality
✅ BMS and its configuration options
✅ Communication with the inverter
✅ Operation at a load of approximately 5 kW
✅ Temperatures under load
✅ Wiring, protection, and connections
✅ Humsienk app
✅ Possibility of expanding the battery with additional modules

During the test, the battery reached over 5 kW of draw and operated under heavy load for several minutes. I also checked the temperatures using thermal imaging.

The manufacturer claims 5.12 kWh, and my capacity test showed 100.5 Ah, very close to the advertised value.

During the test, I also checked the communication with the inverter. The storage unit communicated seamlessly using the Pylon protocol and correctly transmitted information about the charge state and battery parameters.

🔍 I also took a look inside. The cells are laser-welded, the design is very neat, solid copper connections are used, and the overall build quality is truly impressive.

📱 The app is simple and stable. You can adjust security parameters, charge and discharge limits, and communication protocols, among other things.

⭐ MY RATING: 8/10

In my opinion, this is a very interesting storage unit for people who don't want to spend a lot of money on 16 or 32 kWh batteries right away. You can start with a single 5 kWh module and add additional storage units to your system over time.

I highly recommend it for its build quality, actual capacity, and performance under load.
