Is it possible to rebuild a Gen II pack with an entire set of Gen I modules? Does anyone know the difference between and Gen II and Gen I module?
Bad idea. That's equivalent to using an engine with 400k miles to replace a broken engine with 200k miles. If it works, it'll last a week
They will work but gen1 module is weaker than gen2 module. That’s one reason gen1 has more of them. And gen1 modules are older than gen2 modules so that makes them even weaker.
