The following video short was a deleted scene from my new DLG Building Clinic. I demo how to desolder lipo packs and make a 2S into a 1S2P pack for DLG use. Also show how to check 1S voltage in a standard Lipo fuel checker without using the balance port.
Of course only fool with Lipos at your own risk, even small batteries can cause big trouble when not treated with respect. Just buy a battery if you are not good at soldering.
