Higher pinions = safer MMM's? Or no? Someone's lying....

This is why you would use parallel packs to bring the resistance down. Or use a bunch of caps to compensate.

As I see it if ripple is the problem then caps would help, but if the voltage is rising to a dangerous level then you need the TVS as well. To me since we are talking about IR of battery packs the problem would be that you couldn’t shove the electrons in to the battery fast enough so the voltage “backs up” (or rises) to an unsafe level. So then you need something to clamp this voltage to a safe level, enter the TVS that’s what its job is that’s what it does. So basically both are needed if the IR of the pack is too high. What is too high?
