Weatherflow Tempest Emergency Charger

Thanks to https://community.weatherflow.com/t/diy-usb-charger-ready/12519/27 i found a solution to charge for my unusable Tempest Weather Station. Far too less solar charging capabilities in winter. I wish i had this information last December. I had some spare Pogo-Pins. Charging via 18650 LiPo Battery. Starting around 4.2V should be perfect within specs. With this setup i can charge outside the House near the pole and at least temperature readings are still valid. The setup of the Pads seems not optimal for using the bajonet fitting. I prefer to let gravity work for the 3-4 hour charge... I think position is accurate enough to work without Pogo's too. Just use a wire. Check polarity twice. No Guarantee!!!
Hope weatherflow provides a permanent solution for this desaster.
