Im trying to do a DIY RC car with uses two 12v motors as well as some LEDS servos and Arduino components. I was planning on using two 3.7v 2600MAH 25A 18650 battery cells on parallel to have a bigger capacity while keeping the same voltage. Considering this, would I be able with a boost converter increase the voltage to 12v to power the motors and then charge the batteries with a TP4056? Would there be any problems with trying to do this or should I try something different?
I was also think on maybe trying to use four batteries to double the voltage and capacity (or maybe 6 batteries to have triple voltage and capacity), in this case I should use a 2S or 3S BMS right?
Im pretty new to this and I know very little about batteries so sorry if my logic is wrong. Thanks!
