Swedish Vaper PotBelly PWM

£ 21.99tax incl.

The Swedish Vaper PotBelly PWM is a very small unit designed to fit in tight spaces to provide
variable output power in a personal vaporiser (mod).

Not much larger than the potentiometer itself, it is intended as a simple drop-in solution with a
minimalist 3-wire connection setup and can be used as an all-in-one solution or to trigger an external
p-channel mosfet.
See full description for details

Supplied pre-wired with positive wire and 16awg negative wires.

Connecting to a voltmeter can be done easily (see diagram).

Operates on 2v – 18v(max), accommodating 1S – 4S battery configurations.

Recommended minimum coil builds:

2S: 0.2 ohm
3S: 0.3 ohm

Although the onboard mosfet is a high-grade 300A component, due to the small size of the PotBelly
there is a max of 65A recommended for safe operation.

As with all PWM boards, when calculating the load (amps) use the battery’s full voltage as a basis,
NOT the average voltage displayed on a voltmeter connected to the board. E.g:

0.2 ohm on 2S:

Voltage 8.40V (regardless of potentiometer position)

= Current 42.00A
= Power 352.80W

The PotBelly is intended for advanced users with some soldering experience. Be safe, follow the
diagram and enjoy!

V3.5 StealthVape Edition:
  • 1-5% tolerance Vishay or Murata 75v resistors
  • 5% tolerance Johanson TanCeram capacitors
  • 4.3A 30v Diodes Inc. p-channel mosfet
  • 300A NXP n-channel power mosfet (ultra-low gate resistance of <720uOhms)
  • 93PR50KLF potentiometer (50K makes for a quieter vaping experience)
  • Gold-plated Molex C-grid III PCB connector pins to bind the two pcb’s together
  • Soft silicone multi-strand connection wires
