Hello Freinds

I have a power tool BMS whose rated continuous discharge current is 35 A. So per Matador's ampacity table that is cited on these forums in many places, 0.1 mm thick by 10 mm wide strip, 13 of them stacked would give me 36.48 A.
Now the B- and B+ holes within the PCB, can't fit 1.3 mm thick nickel strip

The most I could get in there was about 0.8 mm, or 8 strips. So what is a guy supposed to do? Is there like a surface mounted connector that I can mount to this area? Please send a link to one. Thanks for any solutions! I know the small surface mounted connectors are typically rated at 0.5 A.
Looking at other power tool BMSs, they also seem to have a really small hole. Additionally, looking at manufacturer created BMSs, I think they have really thin nickel, like 0.3 mm thick... Interesting. I see people get lots of current out of them though! Much more than what 0.3 mm nickel is rated for per Matador's table, I guess enforcing the idea that if it is only for a few seconds, than don't worry about it.
