JK BMS and new settings

davecason

Hi Folks.

I finally got a new JK-B2A8S-20P BMS a few days ago, now the fun part. My old (now dead) DALY that i got with the it had no user definable settings.  All you could plug in was the battery cable.

This New JK BMS is asking for lots of variables now - holy crap ! I'm going to start reading some docs I found on the web about: " Voltage Settings for BMS, Chargers and Loads "

In the meantime here's what I have now based on some default settings and a video I saw on Andy's channel ...... does anything look really odd or out of place before I get going with it?

The cells are four :

Shenzhen Basen's 3.2V LiFePo4's With a cap of 272Ah Voltage of: 3.24V IR: 0.12

Here is what's in the JK BMS now for all the settings so far ..........
