A two cell LiPo pack will put out between 6 and 8.4v depending on its state of charge. This is too much for many applications. By adding a voltage regulator to the output, you can construct a 5v supply to power your projects.
Either charging circuit can be paired with one of our high-efficiency DC/DC voltage converters to make a portable high-capacity rechargeable 5v power pack for your Arduino, Raspberry Pi, or LED strip project. These "buck" converters operate at up to 94% efficiency - assuring that you get the longest possible run-time from your portable power system.
