I am considering using 8 of these 105Ah cells from @mkpieters in a 2P4S configuration. Normal usage would be low (0.1 C) charge/discharge rates. I would like to be able to use as a vehicle starting battery in an emergency though (bypassing the BMS and connecting jumper cables directly to the battery terminals. Any thoughts on the quality of these cells? Specs look good but my biggest concern is the M4 terminals with max torque of 8Nm. Thoughts on these securing larger busbars and pushing 2C-3C?

Looking for input regarding the M4 terminals with 6mm insertion depth and max 8Nm torque in a 4wd vehicle application. I would probably attach a SS stud with loctite first, then attach busbar and BMS connections with a nylock nut. I did read of one (or more) stripping out, but if they are not over-torqued should be ok? Is that enough clamping force for say 1/8" or 3/16" busbar pushing 300A? Thanks in advance.
