Inrush current on LiFePO4

If you want high inrush, build from cells and choose external BMS and solenoids.

You can even bypass the protection circuits during crancking the engine if you want to use SSR / FET for the BMS to control normal loads / charge sources by going straight from the cells to the starter[/COLOR].

So, What I proposed is not ridiculous?
As I understand it, there is inrush and start high current.
As in msec "Inrush" 10x run, and "start" sec's 2/3x run. Capacitor charge etc.

on the supposed 200A supporting FETs in the JBD bms, I dont know how to limit the no more than 2C for 30sec spec of EVE without major expenditure/electronic overkill..

Use a slow 500A fuse, they are cheap compared to electronic overkill.
