H2O2-PWM Case Kit V2 - Kit For The Case without Controller Board

Are you interested in building a PWM? This DIY PWM kit contains the predrilled case with all the screws, nuts, washers, lugs, The MosFets, insulators, both capacitors, the diode, all wires, predrilled Heat Sinks, Heat Sink Compound and 12V Fan. Some assembly and soldering required. If you like doing things yourself then this is the kit for you, no heavy equipment required, just you the parts and a few tools.

Status:  1 Case in stock, And will be available soon.    Current Version: V2.0.0


            Update:   Improving the webpage before the world ends today  12/21/2012
            Update:   Added parts for Case  9/17/2009

Now that you have ordered the H2O2-PWM Case Kit you will need a PWM Control PCB. There are 3 different electronic PCB options to chose from please pick one that meets your needs:

These PCB's can be ordered separately as raw PCB, DIY kit or The Pending (already assembled and tested board. The PWM Controller you chose will determine what what PWM you are building.

The H2O2 PWM Case V2 is rated for 75Amps Continuous Current, It is designed to function on a 12VDC charging system that utilizes a 12V Battery. The above  Controllers utilizes Pulse Width Modulation with Auto Current Limiting (ACL). These PWM's add a real punch to the original open source project and utilizes a Pulse Width Modulation Chip to Make the Switching MosFet's run cooler it does this by reducing the time it takes to turn on and off the MosFets. I suggest Installing 4 Mosfets into the H2O2-Case V2 and these units will drive all 4 MosFet's These Open Source board are based on the CCPWM V2 & CCPWM V2H originally designed by Zero Fossil Fuel.

What is needed to assemble this kit, A Large & Small Flat head screw driver, Adjustable wrench or Closed end wrench set, and Soldering Iron.


For all you DIY guys, Here is your chance to build your own H2O2- PWM Case V2 with a minimum of effort. We offer the Drilled Case so all you have to do is populate it with the components that you have acquired. Maybe you are interested in a Kit that has all the parts that are needed to make this an enjoyable experience. Just utilize your soldering skills and have a lot of fun. Remember the PWM controller is not included in this Kit. Now if you are short on time the H2O2- ACLPWM V2  is Available Assembled tested and ready for you to install
