I would please like to know if you have a system to recharge my robot with solar or electromagnetic energy and a plan to connect that system to the battery?
Also if you can suggest me a good rechargable battery for a robot (my robot uses a microcontroller), it would be very helpful.
In order to charge a LiPo battery you can use this charger which provides 5V power for microcontrollers: RB-See-109
With it, you can use a solar panel (RB-See-140), a proximity charger (RB-See-108), a hydroelectric generator (RB-See-99), or any source or current up to 400mA.
