(3). Plug a new fuse into the socket. The P/N of the fuse: 0451005. Manufacturer: Littelfuse.
10. How to configure six isolated/independent 3.3V rails
It is possible to have six isolated/independent 3.3V rails under the following configurations.
(1). Install battery cells or battery holders to BT7, BT2, BT9, BT6, BT5 and BT3 positions.
(2). Short TP11 and TP12, and then short TP5 and TP6 at back side of PCB
Under this configuration, six pure 3.3V battery rails can be used, which are
J1, J2, J3, J4 and
Additional 3.3V rail: J17
The other additional 3.3V rail: J18
There is no fuse for the two additional 3.3V output. If it is possible, please include fuses in the power path.
11. Eliminate possible audible noise
When lower voltage switching mode DC power is used, for example a 12V/4A switching mode DC power adapter,
sometimes there could be audible noise generated when charging the battery cells. The reason is that with lower
voltage, the charger will draw much higher current from the switching power supply. This can cause higher ripple
to the circuit and sometimes may fall into audible frequency range though it still fully functional.
To fix this issue, you can just simply replace it with a higher voltage power supply, say, a standard 18.5V laptop
adapter, or high current linear power supply.
12. Notice of connecting OLED display board with FFC/FPC cable
If you want to move the OLED display board externally to the LifePO4 power supply board, you will need to
connect it with the LifePO4 power supply through the supplied FFC/FPC cable. Please make sure the DC power
(J5 or J6) are fully disconnected before you doing this kind of jobs.
13. How to upgrade 5V DC output to ultra capacitor power supply
a. Install a UcMateConditioner through UcAdpater PCB(optional).
b. Connect J30 to UcMateCoditioner 5V input
c. Connect J29 to UcMateConditioner ON/OFF control input
d. Connect device to the 5V output of UcMateConditioner (rather than J8)
e. Ready to go
Please see UcMateConditioner user
’s manual for more details.
14. How to upgrade battery cells into ultra capacitor hybrid power cells
a. Install UcHybrid boards through UcAdpater PCB(optional) right above the cells that need to be upgraded.
b. Connect to each installed UcHybrid boards through the bridge cable.
c. Ready to go.
Please see UcHybrid user
’s manual for more details.
