Iv been running a single 18650 mech mod for a while with AW IMR 1600mah batteries. Im looking into getting mech box mod but not sure what kind yet. If I do go with a box will the two batteries double the output voltage and also double the max continuous discharge amps? My lowest build is about 0.3 ohms. Also what kind of batteries should I get for this kind of rig? My last set came from RTD but idk if they are still reliable.

So if Im understanding this with a parallel box if I had a 0.3 ohm build it would still be about 45 watts same as a single 18650?
1: mech boxes are built for parallel batteries.
Voltage remains the same; max cdr doubles
Gotcha so with two 20 amp max cdr cells i would be in the clear till about .1 ohm? If so are IMR batteries still recommended for mechs or is just about anything acceptable as long as its a good reputable manufacture and within the max cdr?
Still use IMR. I only run Samsung 25R's in mech's. A mosfet is a small switch that turns a small voltage from your switch into a big current from your batteries to power you rda, tank or whatever. Its the safest way to go and there cheap. Most people on here use the IRLB3034. Its a negative switch. There are numerous wiring diagrams on here. Not hard at all
i see the 25R's on rtd are listed as INR is that the same thing as IMR? Also any suggestions on box mods looking to go with a parallel setup for now may look into a series setup later on. Is the mosfet a must have?
IMR and INR are designations for the battery's chemistry make up. Both types are considered safer chemistry, so no worries there!
Mosfet is for an unregulated box with wires. A mech box is metal with no wires and a mechanical switch. Two that immediately come to mind are the Dimitri and the Cherry Bomber.
If you are builing low resistances that allow a lot of current, a mosfet can allow a separate, low-current circuit to be used for the switch. The switch wasn't designed for all those amps and could otherwise fail.
So, yes, you should get a box with a mosfet.
I just picked up a Rage box mod. It has a mosfet and you can get them in parallel and series. Nice looking boxes. You can get the parallel in dual and triple cell.
IMR stands for "Lithium manganese round", but most high drain/safe chemistry batteries are widely known as IMR chemisty. Samsung's INR stands for (Lithium nickle round). Panasonic uses "NCR" which stands for "Nickle cobalt round". All three are considered considered safe chemistry batteries. Adding either manganese or nickle to a lithium battery makes it safe chemistry.
One last question if a get a box that's done in series instead of parallel does it still double the max cdr of the cells?
No. It doubles the voltage. If unregulated, you will need to build at higher resistances anyway.
