UPDATE sorta:
Given that no docs of any kind came with the unit, including what the specs are etc, email interchange is occurring. I've received no good response yet to my basic questions. Somehow I expected better, to be honest but I suppose I should not be surprised. No answer will mean doing surgery to the pack... but that is another thing too.
I will post my questions & answers received in this "post" within the thread for all to see. They are aware that there is an extended thread/discussion which I will be posting the info to. (I did not give them the link though, but google finds it fast LOL. )
Questions Posted to ShunBin via Amazon
(note, there was a bit of titter tatter back & forth, translation issues likely, so I'm skipping that and just putting the 'meat' here_

Hmmmm, okay… hmmmm

** Always good to let them know they are being observed and given this thread now pops up in Google Search (over 1k views) it could affect future sales. If in doubt, consider the Riuxu (sp?) and BattleBorn teardowns.... BB sales went up apparently...My Questions AGAIN – response will be posted to Public Forum with over 1000 international “watchers”.
There is absolutely no paperwork of any sort included for either the charger(s) or the battery pack.
What are the recommended charging parameters ?
What are the specifications 's of the BMS, is it 100A or the 150A I asked for ?
Why is there no assembly / build sheet with that information, especially as you allow for custom orders / specifications.
- For clarity * Hi / Lo Voltage Cutoff, Lo Temp cutoff (I am in Canada and see -35C) etc the Specifications as you provided.
Can you email OR provide a link to documents for
A) the Chargers S600-12/50A chargers and
B) this pack build & recommended parameters etc
NOTE: Are you aware that there is over 1000 people following this purchase, as well as a few others who have bought ShunBin packs, within a large forum in the USA (being watched internationally). Responses and actions will be posted to that international forum for the general public to see.

- Please respond to all questions, not just one, as previously done.
Thanks in Advance for your assistance,

#1: Hello, the charging voltage is: 28.8V-29.2V ,The continuous discharge current of BMS is 300A,BMS can be suitable for 100A,Lifepo4 is easy to use, what recommendations parameter do you need?
#2: Charging temperature : 0~45 ℃ Discharge temperature : -20 ~ 60 ℃ Storage temperature : -20 ~ 45 ℃ Lo Voltage Cutoff 20V,There is no Lo Temp cutoff ,Only high temperature cutoff, we don't have a manual yet,The charger output current is 50A, BMS (Battery Management System): With built-in BMS for over-current, over-discharge, over-charge, short-circuit, adverse-polarity connection, balancing functions
Hmmmm, okay… hmmmm
