Could someone tell if I'm using the wrong parts, or just wiring it wrong?

My first time wiring a custom saber & it just isn't working. I'm putting the new electronics into a busted, old UltraSabers hilt I bought for cheap years ago & I just wanted to spruce them up. I never wanted a fancy one with the SoundBoard & color-changing, just a reliable dueling saber that's bright & can be recharged without disassembling it. I also used JSTs between the Driver & LED in case I decide to swap colors later.

First attempt:
[Battery + Port + Switch + Driver + LED - Driver - Port - Battery]

Second attempt:
[Battery + Port + Driver + Switch + LED - Driver - Port - Battery]

Current attempt:
[Battery + Port + Driver + Switch - Driver + LED - Driver - Port - Battery]

Each time after finishing the soldering, I plugged the Recharge in just to ensure there was actually power in it. I'd charge for 10-15 minutes, then unplug and press the switch. Every time, no light.

My Parts list:
Power Source:
18500, 3.7V/1400mA PCB Lithium Ion **Replaced with 7.4V/1400mAh** (TheCustomSaberShop)

Charging Port:
2.1mm MWS Recharge Port (TheCustomSaberShop)

Activator:
16mm non-illumimated Anti-Vandal temporary Switch (TheCustomSaberShop)

Driver:
6-Wire LUXDrive 1000mA BuckPuck (TheCustomSaberShop)
Light:
Custom Blue/Cyan/White Tri-Cree LED (TheCustomSaberShop)

Here is my most recent wiring with the 7.4V battery:
