This compact storage discharger is designed for 1S LiPo batteries with Micro JST 1.25mm connectors. It helps extend battery life by bringing cells down to a safe storage voltage.
By default, the unit discharges at 100 mA, but you can configure it to 50 mA by adjusting the onboard jumper (see below). It’s suitable for all 1S LiPo batteries with a capacity of 50 mAh or higher.
⚙️ How to Use
- Connect your battery to the Micro JST socket.
- If the battery is fully charged, discharging may begin automatically.
- If not, press the button to start the process manually.
- The red LED indicates active discharge. It will turn off automatically when the battery reaches 3.8V (storage voltage).
⚠️ You don’t need to monitor the process. The discharger safely stops on its own once complete.
🔧 How to Configure Discharge Current
You can switch between 100 mA and 50 mA discharge rates using the pads on the PCB:
- ✂️ To lower to 50 mA: carefully cut the small trace between the solder pads using a craft knife.
- 🪛 To increase back to 100 mA: apply a small drop of solder between the same two pads.
