Hi
I am building a robot with arduino nano u.C , 4 medium servos ( 100 mA each probably ) . 2 small DC motors ( about 100 mA each ) and maybe a sensor or tow .
The expected needed current is ( 700 mA ) at 5 V
I have to options for batteries ( LI-Py & NiMH ) , both have different voltage levels and mAH ratings for the specified current , all signs indicates that Li-py is better in duration and wight aspects.
But I am thinking of supplying my robot with a solar charger so it can be mobile for Ever . so which one of these options can be charged via solar energy .
Where the construction of the charger is not that difficult ?
any suggestions , schematics , Ideas are very welcomed
