Here is the Tmax Version 2. The original version looked exactly the same but only used a very small 16340 battery. After everyone screamed - they changed it. Its now a 2 battery slot system that allows you to use a 18650 or a 18350. This runs the standard Zmax v3 variable voltage / wattage system but in a metal box mod form. I do not believe the segelei logo will on the mod.
If you like box mods - have at it!
No you can't use both batteries at the same time.
