MORE IO.

EASIER ACCESSIBILITY.

BETTER CONNECTIVITY.

Built around the MP3424 boost converter and the MP2617 lithium-ion charger, the AmpRipper 4000 module can supply a whopping 5V/4A, 20W output with a fast-charge rate of up to 3A.

Smart power path management technology ensures that power to your project is not interrupted, even if the battery or charger is removed. The AR4000 module also accepts a wider input voltage range of 5-14V. Similar to its predecessor, AR4000 is compatible with 3.7-4.2V 1S[N]P lithium ion/polymer batteries. Battery voltage and charge percentage can now be monitored via I2C, thanks to the MAX17048 battery monitor. AR4000 also features improved accessibility with more i/o and expanded connectivity options. Power input and output can be accessed by either USB-C or thru-hole terminals. Connection points for the battery include a JST PH-2.0 connector, as well as thru-hole terminals.

WHY KICKSTARTER

As makers, we were tired of dealing with the unreliable, underpowered, inaccessible battery modules that are currently available. So we made our own, the AmpRipper 3000, and sold them to makers suffering from the same headaches. Since the beginning, our goal with the AmpRipper series has been to provide makers with powerful, durable, intelligent battery charge & boost modules. Taking what we’ve learned from our first module, we set out to design an even better one, the AmpRipper 4000. In addition to scaling up the AmpRipper’s capabilities, we also want to scale up its production. As a platform that helps fund and spread the word about new ideas and projects, Kickstarter is the perfect place to do just that with our latest AmpRipper. 

In order of priority, here’s what we hope to get from this campaign.

  1. Feedback on our design. Getting critical feedback about the Ampripper 4000 and how we can make it better is of the utmost importance. We want to make this product as useful to makers as possible. Feedback about aspects you wish were better or new features you think we should implement help us do that. 

  2. Spread the word. One of the biggest struggles we had with our previous module, the AmpRipper 3000, was quite simply getting the word out about it. We’re a team of makers, artists, designers, and engineers, not expert marketers. However, with Kickstarter’s platform, we can skip the confusion of marketing and talk to the maker community directly.

  3. Funding. While making the best battery module we can is our main goal, we also want to make it as affordable as possible. We plan to do this by manufacturing the AmpRipper 4000 in larger quantities. However, the upfront costs associated with these quantities currently prevent us from pulling the trigger. This is why we need the support of backers to help fund the project.
