What is the meaning of the following UPS PSU warning message?
SmartUPS V1.00,Vin NG,BATCAP 61, Vout 5141
I have not yet found the version 2 of user guide, so I don't know if the PSU is using UART serial AT commands to hand shake and then text string to report status.
For the following message:
SmartUPS V1.00, Vin NG, BATCAP 61, Vout 5141
My wild guess is the following:
SmartUPS V1.00 = software name and version
Vin NG = no idea
BATCAP 61 = Wild guess- perhas Lipo high voltage protection capped to 6.1V
Vout 5141 = Voltage output = 5.141V (90% sure)
I think if you used a DMM to confirm UPS output is around 5.14V, then
there this smart UPS should be working OK. No worries.

Note 1: Draft answer to delete later
To the OP: Thank you for your clarification. So you are talking about the new version V2.0.
However I did notice that there is the new version, and I downloaded the user guide from that product page. Looking back, it is that V2.0 product page not up to date.
Anyway, can you give me the web link to the user guide for V2.0.
By the way, my imgur image library is full and cannot upload any more images. So I have to put the image I want to add to this comment to the answer section instead. If I cannot complete my answer later, then I will delete my draft answer. Cheers
