Overview
The JHEMCU Ruibet 2β6S lithium battery discharger module is designed to discharge supported battery packs while measuring and displaying pack voltage. It features an onboard voltage display, a discharge status LED, and cell-count selection for 2S to 6S operation.
Key Features
- Measures and displays battery voltage (3-digit voltage display)
- Built-in LED discharge indicator
- Two working modes:
- 3.8V Discharge Mode (default): discharges the battery to 3.8V for long-term storage without use
- 0V Discharge Mode: insert the 2P jumper cap to enter 0V discharge mode
- Supports 2S, 3S, 4S, 5S, and 6S discharge
- Battery interfaces: XT30 / XT60
- Onboard control button for selecting the corresponding discharge voltage level

What's Included
- LIPO Discharge x1
- 2P*2.54MM jumper cap x1
Usage Method
- Determine the battery type and cells, then press the Button to select the corresponding discharge voltage level.
- When the LED is ON, the module is still discharging. When the LED turns OFF, discharge is complete.
Note: In 0V discharge mode, ignore the voltage display value until the white LED goes out and the discharge ends.

Details

Clear onboard labels make setup straightforward: select 2Sβ6S, choose the discharge mode, and monitor pack voltage on the display.

Compact discharger board with an integrated 3βdigit voltage readout and both XT30 and XT60 battery interfaces.

Lightweight build keeps it easy to pack in a field kit or toolbox.

The status LED indicates active discharging while the display provides a quick voltage check at a glance.

Use the button to select the target level for your pack before starting the discharge cycle.

Printed reference voltages on the housing help confirm the correct cell-count selection.



Typical discharge current and power vary by cell count; refer to the table when estimating discharge time.
