- Well-known Chinese manufacturer Bejing XD Batteries with experience in battery construction since 2006
- 60% Savings compared to products from German retailers
- CE, UL, ISO9001, RohS certification
- 5 year guarantee from the Chinese manufacturer
- By default, a waterproof BMS with 100A is installed at 12V, peak load 300A (+ 50A / 3sec),
At 24V and 48V standard BMS 150A (peak 450A) - higher output possible
- Up to 4 batteries can be connected and charged in parallel
- Series connection is not possible (then use the appropriate battery type with a higher voltage)
- Consists of prismatic cells from Chinese manufacturers
- Closed, waterproof housing
- Batteries with flat terminals (screw-on round terminals can be ordered)

- There were quality problems with some batteries regarding:
- Incorrect installation position of the cells
- Fixation of the charging electronics with adhesive tape
- Space wasted due to oversized housing with foam filling
- Soldered power cables instead of connections with compression sleeves
- Loose compression sleeves on power cables
- Uneven cell charge level on delivery
- Incorrect display of the battery capacity in the app
- Sale of user batteries with 1000 charge cycles according to the app
- Also available with Bluetooth for displaying voltage, current and capacity via an iPhone or Android app (Liontron LX Smart BMS)
- The Android app is very rudimentary and can do no more than shown in the picture
- A lot more is possible with the iPhone app
