4 cục pin lifepo4 này dòng bao nhiêu amperes anh nhỉ? Trong file tech của allo em lại thấy họ ghi:Vụ Allo Isolator trích từ tài liệu của nó
We recommend using LIFEPO4 batteries, and the Isolator will in turn provide 5v/06A using LT3042 and 3.3V using LT3042 LDOs.
This pack can hold up to 4 x LIFEPO 18650 batteries and has a DC jack with a 2.5mm pi and a 5.5 outer diameter.
The batteries are arranged 2 x 2 in parallel releasing 6.4V.
4 cục Pin 18650 LiFePO4 = 6.4V.
For the Primary Side of Digital Isolator Power(3.3V_A side)) will source from RPI(5V) convert to 3.3V through LDO. For the Secondary Side of the Digital Isolator Power (3.3V_B side) will source from the external DC Jack (JP2) or External Battery Connector (J29).
And the Isolator will in turn provide 5v/06A using LT3042 and 3.3V using LT3042 LDOs.
Secondary Power Supply rating : +6V to +15V ~ 3A
Power Sequence : First Power on the Secondary Power(DC JACK or Battery). Then Power on the RPI/SBC power.
