Ive had a desire (Not the time) to get into home automation, read my batteries and communicate with my inverter, so started researching, and thanx to this forum found some answers and how to.
So I pulled out my Link sprite, bought some Tuyo switches, a bit of zig bees, mixed in my 403 Mhz and 433 Mhz's, dusted off my arduino and looked for Raspberry Pi,  No one had stock, and the ones that had 2nd hand were asking prices double the value. Everything went into a bag, and thrown into my sock drawer. New hobby..... I started looking for a 3d printer, and bang found raspberry Pi 4 back in stock at the PiShop.co.za. I await my delivery and ....... more time

The BMS is my big dissapointment, I really was expecting to find Huge meat, watercooled system (Daly style), but I got this. (Dala style)
Where do I go from here....
Are these cells a different manufacture Deep cycle to crank to golf cart
Individually : Can it be recharged, checked for the bad cells and repurposed for solar use ? - or tell the company "you're problem to dispose", because repair is virtually impossible. Although the one battery supplier said he  'knows a guy' "Of Course - I replied"
In this pack i found 2 cells bad - but it is packed 4s2p - so maybe 1 is faulty and destroying its partner.
Looking up the battery replacement i found 1000 Euro   +/- R20K replacement value.   Please flush my oil.
 
 

Waiiiit.   RJ45 - Once a standard for cat 5 Network communication. Then adding Power over ethernet added, Now rs232 then RS485 then Can-Bus then remote switching, then combinations of RS232/RS485/Canbus and seeing positive +12V and or +5v . all in a 8 wire termination.
And I still dont understand Earting (1 wire) on a DC system
