voltage
A circuit pulls an amount of current from the source. The source does not feed its rated current into the circuit. So you don''t need to do anything to ''reduce amps''. When selecting your power source you need the correct voltage and at least the required current. The circuit will only draw as much as it needs.

This represents a large current from a relatively small battery of about 800 milliampere (mAh) hours. A current pulse of 2.4 amperes from an 800 mAh battery, for example, correspond to a C-rate of 3C. This is three times the current rating of the battery. Such high current pulses can only be delivered if the internal battery resistance is low.
