Sparkfun LiPo Charger Plus (USB-C) not charging

Just got myself said charger and I am a bit at a loss here. Whatever LiPo I try the charge LED will only go on for a split second and then stays off while the power LED (red) stays on as it should . I’v tried different power sources from my computer’s USB 3.2 connectors up to 150W chargers for consoles and phones, but nothing seems to work. As for LiPos I’ve tried different 3.7v 1C ones from 340 up to 2000mAh.

Hope someone can help me out here :slight_smile:

Double check that your battery’s polarity matches the Charger’s

Test with a 1Ah battery if you can (default charge rate is 1A)…or swap the resistor to one that matches w/e battery being used
