A. Safety warnings (please read first)
LifePO4 battery cells are high density energy storage devices. They could have risk of leaking, overheating, smoke,
fire, explosion or damaging the circuit board if don't use properly.
1. Never short circuit at any time during storage, assembling and operation.
2. All battery cells are internally connected together in parallel on the PCB. You must never reverse the positive and
negative terminals when assemble/solder them into PCB. Reversing battery terminals could be very dangerous.
3. Have to wearing protection glasses, gloves and other safety equipment when assemble/disassemble batteries.
4. Never expose battery and the battery power supply board under high temperature, sunshine or water.
5. In case of any issue happens, please put batteries or battery power supply board in a fire proof container. Also
has to make sure the power adapter is disconnected.
6. Please follow other common battery safety instructions.
7. It is your responsibility to ensure the safety of DIY activities.
B. Introduction
Battery is a kind of passive power supply without any feedback. Comparing with active power supply such as a
voltage regulator, it has much better load transient response and less noise. This LifePO4 pure battery power
supply is a completed solution to provide battery based clean power voltage rails to DAC and other sensitive audio
applications.
