The Complete Guide to Voltcraft BS-15 USB Software Download: Installation, Drivers, and Troubleshooting

The Voltcraft BS-15 is a popular, budget-friendly battery tester (capacity meter) favored by hobbyists, DIY electronics enthusiasts, and small repair shops. It allows you to measure the voltage, current, and capacity (mAh) of various batteries, from AA/AAA cells to larger Li-Ion packs. However, to unlock its full potential—namely, generating discharge graphs, logging long-term data, and analyzing battery health on a PC—you need the correct Voltcraft BS-15 USB software.

  • Use a generic CP2102 USB-UART adapter ($5) and solder it to the BS-15's internal TTL pads.
  • Use Sigrok (Open source logic analyzer software) – It has a Voltcraft driver that works perfectly with the BS-15 hardware.
  1. Do not connect the BS-15 yet.
  2. After software install, navigate to the program folder (e.g., C:\Program Files (x86)\Voltcraft\BS-15).
  3. Look for a subfolder called Drivers or USB Driver.
  4. Run CP210xVCPInstaller_x64.exe (for 64-bit Windows) or the x86 version.
  5. Complete the driver installation wizard.

Conclusions: The Voltcraft BS-15 remains a capable instrument when liberated from its obsolete software. Our case study demonstrates a reproducible methodology for rescuing thousands of orphaned USB test instruments. We provide the full source code and compiled binaries as a public archive, eliminating the need for unsafe "software download" searches.

Tip: The software includes a data logger mode. Go to FileLog to disk to record long-term measurements.

Current version as of 2025: Most BS-15 units ship with software version 1.1.2 or 1.2.0. The software is often labeled "Voltcraft BS-15 PC Software" and requires Windows 7, 8, 10, or 11.

If you continue to experience issues, the Voltcraft user forums (often hosted within the Conrad community section) and electronics hobbyist forums (like EEVblog or Reddit’s r/batteries) are excellent places to ask for help—just mention you have already installed the drivers correctly.

Step 5: Verify in Device Manager

  • Open Device Manager (Win + X → Device Manager).
  • Look for "Voltcraft BS-15" under "Sound, video and game controllers" or "USB devices".
  • It should not have a yellow exclamation mark.
