I am very pleased that the goods remain in perfect condition after transit.
I built a large 24V LiFePO4 bank for my workshop, and I needed something that could handle 500A. This monitor was the perfect choice. The rectangular display is easy to mount, and the setup was very straightforward. It’s great to have both the physical screen for quick checks and the Bluetooth app for deep-dive diagnostics. Highly recommend this to any serious DIY builder who wants reliable, accurate data.
I finally have an accurate way to monitor my off-grid cabin’s battery bank. The EJ-BM16 display is clear even in dim lighting, and the data accuracy compared to my old analog gauge is night and day. It’s been running flawlessly for a week, and the app interface makes it super simple to check the status from my phone while I’m out doing chores around the property. Solid piece of engineering.
Clear product manual included in parcel.
Great support for after-sales troubleshooting.
