HELP!! Aluminum tin box mod

[jonny2hottie]

This is one of the few mods ive made and im having problems with the voltage output. i attached 2 rcr123 battery housings and connected the positives at the trigger switch. is that whats wrong? i used the aluminum box as the grounds for each connector. for some reason when i put both batteries in with a 3.5 atty it vapes really light like its only doing 3v. so i took one of the batteries out and put in an LR and it vapes great just like an LR would at 3v. i got froggy and tried to place both batteries again (6V) with the LR and it vapes the same as 3v. no matter if i remove the top or bottom and only use 1 battery to vape it delivers the same 3v. im lost! how come each terminal works seperately but when i place both batteries in it i still only get 3v?

should i just use both 3.7v 16340's and an LR? since it only seems to run one battery no matter what maybe it would use up one until its dead then begin to use the other?! idk

help please!

You have your batteries in parallel and they should be in series if you want to double your voltage (3v x2). What you're doing in parallel is not doubling your voltage, but doubling your mAh, in theory doubling your battery life in the mod.

Connect the positive on the rear batt to the negative on the front batt, and have a positive lead off the front batt and a negative lead off of the rear batt, like you're staking them. This will give you 2x the voltage that you're looking for.

it looks like you're wiring your batteries in parallel as you have the ground connected to the tin box...thus the 3V performance. wire them in series and knock yourself out

Cool looking mod! There are some creative people around here!

Be careful how you insert the batteries or you could really knock yourself out.
Maybe a little insulating tape around areas of the box that might contact the battery contacts would prevent an accidental short. (I assume you changed the double wires to the switch).
