    Li-ion battery charging

    Hey dls13dls,no, you can not just use a potentiometer.You need a step down converter for that.Look at amazon or eBay for a step down module, with an LM2596 ic on it. Then connect the input voltage and measure the output voltage of this module. Finally adjust the poti on this module to get the right output voltage. Then connect it to your toy.Cheers, Phil
