Attempting to figure out methods of dropping and regulating power.
Power Source : Li-Ion 4S4P Pack
~Cell Voltage Nominal: 3.7V
~Cell Current Max: 2A
~Pack Voltage Min: 12V
~Pack Voltage Nominal: 14.8V
~Pack Voltage Max: 16.8V
~Pack Current Max: 8A
Test Load Lamps
(1) 5V .5A 2.5W
(2) 5V 1A 5W
(3) 5V 3A 15W
(4) 5V 10A 50W
Overall Goal: Efficiently modify the Li-Ion power to a constant 5V, assuming various load current requirements. Understand variations in methodology based on load current requirements.
Ultimate Goal: Adjust output from 4S1P to a constant 5V with a maximum draw of 3A
Top Left SPDT: Select voltage min\max
Top Left SPST: Main Power
Top Right SPDTx3: Load Selection
Circuit should only be changed between Terminal A of the Relay to the left, and Input Terminal on the first SPDT Switch on the right.
