Why not just get these protected batteries instead?

5cardstud, because he has unprotected 18350's he's trying to figure out what to do with.

This link might be helpful.
All-Battery.com - Rechargeable batteries & Chargers - PCB/PCM/BMS for Li-ion and Li-Polymer Battery Packs
Custom saber shop also has a few protection circuits.
You just have to figure out what circuit meets your required needs.
