How big are the screws for lithium battery solar container

The terminal and bolt sizes are metric and the numerical signifier is the dimension in mm. So when people build their banks with large LFP cells which come with these relatively small M4 terminal screws, what is the thinking on terminals? for instance my existing battery cables (to charger, breaker, load) are 2 gauge or some even bigger and have the clamp terminals on them. How to properly tighten screw terminals on lithium batteries? Hello People, im building a small solar system for my fathers garden, 2x 100W Panels, MPPT Charge controller, 200Ah 12V LiFePO4 battery and a 3000W Inverter. Rebling feed-throughs are the lowest cost terminals for 100 Ah to 10 KwH lithium batteries. Our TFT-style terminal (without mounting ears) is the most economical, smallest footprint, simplest environmental seal, battery terminal which can reduce connector costs on a single microgrid energy storage.
