☆Doesn't Support Series Connection and parallel Connection

I have seen the JBD do over 200A for over an hour with no issues, in fact the settings allow it to go up to 230A.

JK is cutting corners using cheaper mosfets, also the 7 guage wires for 200a is on the low end, why have wires at all just put terminals.

Here is the spec sheet. They clearly say 350A for 2-minutesView attachment 95546

Yes it does and you can BUT it is NOT WISE... That is there for the rare if ever occurence happens... It is NOT anything to even consider using, it's a failsafe.

I agree fully. My original point was that Andy was TESTING the first ever 4s JK sent to him for that very purpose and his objective was to push it until it tripped. He was marginally over the max discharge current and had the time set per the spec and default values for the purpose of seeing what happened when it tripped. My comment was that JK states that they can handle up to 350A for 5 minutes. What he found is that it did indeed trip but at the cost of one FET. In spite of that the BMS was still fully functioning all be it at 19/20 of its ultimate current handling capacity.

It was not a comment on the advisability of doing so.

On my build I will have a 150A class T fuse so that the fuse will limit me to below the rated capacity of the BMS to fail-safe the fail-safe. My goal is to NEVER require my BMS to do anything to save me other than the active balancing.

There is a big difference between what someone will do for the purpose of "testing" vs what is good SOP.

I personally think that Admin of this forum should start new YouTube videos where he torture BMS to find right size fast-acting Class-T fuse so it makes easy for others to pick right hardware. He already torture battery packs by destroying them to show what is inside.
I would be happy to see him take my advice seriously.
