Lithium Ion Battery Chargers
Li-ion battery chargers are complex and challenging circuits. They require accurate current and voltage settings and monitoring as well as a constant current and constant voltage. If these accuracy requirements are not met, the charger will fail to completely charge the battery and reduce battery life, or otherwise permanently reduce battery performance. Selection of the proper current sense resistors can help prevent this from happening, in airplanes and elsewhere.
