I have a project that uses a 3.7V 850mAh battery, that is charged with an adafruit lipo charger . I decided I wanted to upgrade to a higher capacity battery and went with this 3.7V 3000mAh battery. When connect the battery, it does absolutely nothing, even after charging it overnight. I thought the battery might be defective, so I ordered another. Same thing. Then I ordered one from another vendor. Same issue. My project works fine with the 850mAh battery and with a 1500mAh battery. Is there something about these higher capacity lipo batteries I'm not understanding? It's really frustrating. Any info or suggestions would be much appreciated.
Thanks.
