Key product points

Get to know your LiPo batteries with real test data. Built exclusively for RC Discharger Regenerative Dischargers, Benchmark brings battery testing, archiving, comparisons, cycling and break-in programs into one app for Windows, Android, iPhone and iPad.

Test two packs side by side

Test two LiPo batteries under the same conditions. Review how each pack performs during the run and use real measurements to compare them.

Follow live battery data

Monitor voltage and discharge curves, capacity and temperature as the test runs. See how each battery behaves throughout the discharge.

Compare up to four batteries

Select up to four saved batteries and review their curves and detailed results together. Compare packs and track performance changes over time.

Keep every test organized

Automatically archive completed tests with detailed result sheets. Use saved battery profiles, unique battery numbers and test history to keep track of your packs.

Run cycling and break-in programs

Choose pre-programmed cycling and break-in routines. Run an individual break-in step or select the complete sequence to run all steps automatically.

Calculate current from saved capacity

Save the battery capacity once and select the pack on the bench. Benchmark calculates C-rate-based program currents from that capacity, reducing repeated manual calculations.

Build your Battery Benchmark setup

Start with the required temperature sensor, choose a wired or wireless connection, then add a printer or a stand with tablet holder.

RC Discharger hardware only: RC Discharger Battery Benchmark is compatible exclusively with our RC Discharger regenerative dischargers.
Important: The temperature sensor is mandatory. RC Discharger Battery Benchmark cannot run a battery test without it.

TabletBench notes
Galaxy Tab S10 FE (SM-X520)Main bench tablet — proven through complete runs on both channels.
Galaxy Tab A7 Lite (SM-T220)Proven live at −20 A with cell voltages and IR. Its 8.7-inch screen is compact, but the USB connection is solid.

Buying today — best fit first

Approximate prices are provided only as a buying guide and can change.

TabletApprox. priceWhy it fits
Galaxy Tab A11+$200–300The budget bench: current Android and years of updates ahead. The natural second tablet.
Galaxy Tab S10 LiteAbout $400Mid-tier choice with a larger screen, from the same family as the proven Galaxy Tab S10 FE.
Galaxy Tab S11 / S11 Ultra$675–900+Flagship performance. More power than the bench requires, but an excellent premium option.
Galaxy Tab Active5About $550The pit-lane choice: rugged construction, glove mode and a swappable battery.

Known bad — with the reason

  • Galaxy Tab A8 (SM-X200): The tested unit showed a documented failing USB-C port daughterboard, matching the connect/disconnect loop captured in its kernel log. The port is repairable with a replacement daughterboard (approximately $15) and an iFixit repair guide; otherwise, skip this model.
  • Amazon Fire tablets: Fire OS is not supported for the RC Discharger Battery Benchmark Android app.
  • Older or low-memory tablets: Avoid Android 12 or older and devices with less than 4 GB of RAM.

Before buying an Android tablet: check this list, choose the USB Benchmark Adapter for a wired connection or RCD Link for wireless, and connect the mandatory iCharger temperature sensor.
