I'm not sure if this is the right place for this, but I want to convert my unused MVP 2 into an unregulated box mod. Any ideas on how to go about this? I want to replace the internals with a single, high NaH 18650 or maybe two 14500's. The batteries will need to be easily removable for charging. I may even want to replace the original 510 connection with one that will sit flush. That's about all I have for now, any help would be great.
