LifePO4 MkIII pure battery power supply user

’s guide 

By Ian Jin, May 15, 2020 Ver. 1.01b (Draft) 

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. Have to use 

80W or higher power iron

 to solder battery holders, batteries or connectors to the board. 

8. 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.   

 

C.  Highlighted Features and Specifications 

 

Five independent voltage rails 

Two 3.3V LifePO4 battery direct isolated voltage rails for clock and DAC section. 

Two 3.3V-13.2V battery direct isolated voltage rails for analog section and other sensitive circuits. Each of 

the rails can be configured as 3.3V, 6.6V, 9.9V or 13.2V separately. 

Additional 5V 2A linear LT3042 regulated DC output for digital section (non-isolated, can be 

enabled/disabled).
