    Modular Arduino Power Cube

    Good trick to power 5V modules with lower voltage ! Yet I wonder how the small step-up & charging module can manage the charge of the battery'ies). Is it mandatory to use 3.7V ? What happens if you supply with 3V using 2x AA NiMH ? I doubt it is suitable for any battery technology whose charge process is really different (NiMH/LiPo) ? Can you share the reference or datasheet about charging module ?
