Hello! I want to create an electric toy which includes a motor that works with a 7.4 V Li-ion battery. The battery needs to be charged and I want to use a micro usb-c port/board for that.
Question 1: the 7.4 V batteries that are typically used for these toys are between 500 mAh and 1800 mAh. The higher the mAh the larger the capacity = the longer the duration? What else should I consider?
Question 2: I want the loading of the li-ion battery to be safe and but quick enough. What should be the specification of the micro-usb c charging board? Would this board work: TP4056 Micro USB 5V 1A 18650 Lithium 3.7 V Li-Ion Battery Charging Board or as the battery consists of 2x3.7 V Li-ion batteries (see atatchment) should I find something else ?
Thank you for your help,
Peter
