As many of you Raspberry Pi fans out there may have noticed, we recently added the awesome Pi Supply PiJuice HAT to our catalogue, and we’ve been thoroughly enjoying the portability that these quality expansions can offer. However, if you’re like us, and enjoy getting the most out of every project you Make, then you may have also found that the 1820mAh battery included with the PiJuice HAT was simply not large enough to host some of the really exciting projects that we wanted to do.

This is why we’ve chosen to add this 12000mAh PiJuice LiPo Battery to our catalogue too, in order to give your PiJuice HAT even more power to outlast the many hours in each day and maintain excellent operational efficiency throughout. This allows you to create a truly self-sustained Raspberry Pi project when used in conjunction with a natural energy source like Solar Power, as it offers up to 66 hours of standby/idle operations, up to 47 hours of 1080p video playback, and even as much as 28 hours of 1080p video recording – ensuring that your Pi project can last through more than just the night-time hours, and can actually power on through multiple days depending on what application you are utilising it for.

So, if you love utilising your PiJuice HAT, but are looking for a battery that offers around 6.5 times the capacity of the original BP7X 1820mAh battery, then this is an awesome solution that perfectly replaces the BP7X with very little effort required. And, of course, with Pi Supply being the awesome brand that it is, they’ve provided a really handy PiJuice Battery Replacement Guide, so you can simply follow the easy steps and replace your old battery with this much larger 12000mAh LiPo Battery.

Typical Applications for these 12000mAh 3.7V PiJuice LiPo Batteries:

Despite the fact that these are primarily stocked for the Pi Supply PiJuice HAT, we Makers can’t help but think about the incredibly wide range of different applications that it can be used for. However, in running with the PiJuice HAT theme, we found these massive capacity batteries to be particularly awesome for the following projects:

  • Building a self-sustained sensor system (so much alliteration!) for an office, warehouse, barnyard or even small manufacturing plant, which monitors a wide collection of different sensors and modules, while powering itself from the battery and charging up during daylight hours.
  • Creating your own customised Pi-based Laptop, affectionately known as a “PiTop”, that you can take with you on long travels, offering up to 47 hours of 1080p video playback for those extra long flights, train rides or stop-overs.
  • Making a nature-watcher, which begins recording once motion is detected and then goes into idle mode after a certain period of no motion – relying on solar energy or other natural power sources to keep the battery charged and ready to snap up those buck, birds, bush-pigs and whatever else crosses the path of the camera and motion sensor.

One of the most exciting aspects about this battery is that the massive capacity allows it to be used for an incredibly wide range of different applications, with even hefty operations like 1080p video recording being relatively lightweight in terms of the demand from this battery. As such, the choice of what to do with this battery is completely up to you, and of course, if you think that this capacity would be wasted on whatever project you’re considering, we also offer the smaller (but still beefy) 5000mAh PiJuice Batteries that still offer excellent capacity but might save you on unnecessary costs depending on the demand of your project.

Pi Supply is a fantastic brand that truly personifies the open-source movement. Having been founded by a single individual with a passion for electronics and audio, and growing into a world-recognised brand that now supplies specialised expansion boards to a global community, the humble hobbyist beginnings of Pi Supply began with the simple need for a convenient power-switch for a Raspberry Pi board stored under a bed.

Since their humble beginnings, Pi Supply have grown to be a full team of passionate Makers who truly live up to the name of “The Maker Emporium”, with over 7 different product ranges launched over Kickstarter, and a growing catalogue of over 800 items now available – all with fantastic after-sales support, which is something that we consider to be extremely valuable.
