The device uses a CC/CV algorithm to charge the battery. Thanks to the ultra-low consumption architecture, the charger is suitable for low-capacity cells such as thin film batteries and can use low energy sources such as energy harvesters. A 5 V input like a standard USB port can be used as a voltage source as well. A specific version (-L) is available to c...
