Hello, Sorry for the late reply—I somehow missed the notification about your post. The battery pack contains two 18500 Li-ion cells (2040 mAh each) connected in series, resulting in a total capacity of 15Wh. The built-in charging electronics support 2A fast charging, so if your power supply can provide that current, the pack can be fully charged in about 1.5 hours. This battery pack was originally designed for the LEGO HUB 88012, which has built-in output protection. Therefore, the pack itself includes protections related to the charging and discharging of the Li-ion cells—such as overvoltage, undervoltage, over-discharge, short circuit, and overheating protection. Hi Friedl, Thank you so much for the kind words! I really appreciate it, and I wish you many hours of fun and carefree playtime!

Hi all, Just a quick update — the EnBo battery pack for the LEGO PU Hub is now available in the Phondly webshop. Stock is limited, so if you’ve been waiting to pick some up, now’s a good time. To help keep shipping manageable for everyone, we recommend a max of 4 units per customer. For now, shipping is available only within the EU. Here’s the link: https://phondly.com/shop/ Looking forward to seeing what you build with them!

Hi all, I didn't give up. I'm still working on getting the battery pack into production. Since the injection molding process is not worth it in small series, I insisted on 3D printing, but now with SLA resin-based technology. You can see the improved quality of the new box compared to the previous version: I am working on a small batch production of 50 pieces. First of all, I want to satisfy the needs of those who signed up to the email list after the kickstarter campaign, but the remaining pieces and the pieces of the possible next series will soon be available to anyone. More information coming soon

Hi,Thanks Please choose European Union as destination for shipping

Thanks for the trust you have in advance, but there are still a lot of things left until the product hits stores. One of our plans is to sell the product through our own website https://www.phondly.com and through LEGO stores that are open to it. At the moment (I don’t know how the world economy will change in a year), I could say that the price of the base line pledge (75€) in the campaign is in line with the store price. Allow me one more thought, don’t let your orphaned existing C + HUB rest on the shelf untapped, rather choose one of our great offers to help us get the fund we need to complete the project. :)

Not from this package because OTG is not turned on on the charger IC for some reason, but you can use any power bank to increase capacity

Hi, added on request. We look forward to welcoming you as a potential backer. :)

The kickstarter campaign is live now: https://www.kickstarter.com/projects/phondly/enbo-pu

Hi Everyone, We have been working on a project for 1.5 years to finally find a solution to the problem that LEGO does not offer: a rechargeable battery for the technical Powered UP HUB. Because LEGO is relatively slow to update its products in this area, we decided to give our unique battery, the “Phondly EnBo PU Battery Pack,” a chance. Over the past 4 months, we’ve developed our prototype to such a level that we thought it was time to introduce and launch a Kickstarter campaign to raise money for our first production line. The product itself is an integrated solution for 2-cell li-ion batteries, combined with an electronics that provides fast charging via the built-in USB-C connector, power-path management (for stationery models) and consistent output performance throughout the full capacity of the batteries. . The key features are: - lighter than 6 alkaline batteries with holder - constant 9V output voltage - Withstands high power consumption (tested for 5A demand) - power path management, where LEGO creations can be operated while the battery is charging using the power of the connected USB cable - there is a charge indicator LED (lit through the brand logo) - through LEGO or other third-party applications, inform you that the battery is low by turning off the voltage conversion before the batteries are completely discharged. - can be ordered with two types of cover for the old snap-in HUB or the new screw HUB (fully replaceable on the base box) - With the help of you (the sponsors), the appearance of the product will be similar to that of LEGO (better quality injection molded case made of ABS plastic) - the case design allows to tilt the battery out from the HUB We have so far financed the project 100% on our own, but unfortunately we do not have enough capital to finance the production, so we turned to the LEGO community to help us achieve our goal in a kickstarter campaign. As for kickstarter campaigns, you need to know that everything works on an all-or-nothing basis, meaning we only get the money we’ve raised during the campaign if we’ve reached or exceeded our goal. As a supporter of the campaign, if the goal is not met, you will not lose your prepaid money, the amount will not be deducted from your card at the end of the campaign. So if you want to be a part of this story and feel committed enough to help this product get into stores, please help us reach our minimum goal of € 60,000 or more by supporting us on kickstarter while choosing a a reward for yourself that you are happy with. On the other hand, if we don’t achieve our goal, we won’t get paid to continue working on this great product. Our Kickstarter Campaign page is: https://www.kickstarter.com/projects/phondly/enbo-pu

No, I'm so sorry I haven't posted here yet, I'm just trying to catch up somehow. I promise to make a new topic here today about it

The space is not that big especially on the PCB but here is a picture of the assembled USB port

Hi, Here is our choice which is on the pcb:

Okay, here is the other official possibility: https://www.phondly.com, this is our website.

Please be patient for a few more days and more info will come. It is so certain that the campaign will start now in May. (I think there will be very good reward packages) For the latest updates, please follow our official Facebook page: https://fb.me/phondlydesign

Hi, yes, we are currently trying to put together a kickstarter campaign to fund the first manufacturing run.

I felt something painful when I was driving the models with my mobile during the shooting of the upcoming kickstarter campaign. So after a successful campaign, I will definitely be working on a new remote control. :)

Hi, Thanks for the comments. I’m going to use injection molding and raise money at the kickstarter to fund the first production bunch. I’m busy just finishing my campaign page, but I’ll update my contact information on my website afterwards. This stuff is a prototype right now, and it will a commercial product only be after a successful Kickstarter campaign. In the meantime, please contact me on my official facebook page https://fb.me/phondlydesign or here or at kisgergo@phondly.com Gergő

Hi, Sorry, this will be a commercial product, so I wouldn’t share the internal structure (sketches, etc.), but if you want to support mass production, you can do so in my forthcoming Kickstarter campaign. In the meantime, for the latest news, please follow Phondly’s official Facebook page here: https://fb.me/phondlydesign

Another step forward, better quality 3d printed boxes have arrived. 4 beta prototypes are ready and waiting for testers.

Sneak Peak :) (PF LIPO box is on it's way) Battery Pack for Lego Power Function Battery Box v5 by Gergely Kis, on Flickr

The prototype is still in a very initial state at the moment and I still have a lot to do until production. At first I thought I would sell the package without a LiPo battery to make it easier to ship overseas, but I really want to provide a complete solution so I would still leave the question open for now. The original AA battery insert is around 159 g (165 g with the original cover) and this new design is 102 g with the cover but without the 4 screws, but currently the case is made of PLA and not ABS plastic as it will be in the final version. Thanks, I looked at all the PCB placement options in the box, but the space was so limited that I ended up having to go in that direction. I would rather sell the battery pack complete, selling PCBs separately would not be an option at this time.

You may be right, but I think it can be measured in half a year when the BMS drains the battery. The typical BMS input current (overdischarge) is between 0.1 to 10uA and 10uA is a very high number here. Thanks. My main intention was to keep everything looking original, I just wanted to avoid the use of not very environmentally friendly AA batteries with some extra power. I hope many people think similarly.

I thought the same at the beginning but I also wanted to keep constant output voltage as long as I could. The LiPo battery can easily keep up with the power demand, so I chose a powerful boost converter for the output. Thanks. That's exactly what I did. USB charger ----> BMS (Battery) ----> Boost converter ----> LEGO HUB

You may be right, but I thought a lot of people already have a motorised Technic kit from the last 5-10 years and want to use it without having to redesign and replace all the PF parts. I think I need to do a market research about it :) Thanks, I am using a BMS directly on the battery terminals and it cuts connection around 6V. Those are cheap little circuits and working very well in case of overcharge, overdischarge and overcurrent. I have built 3 Battery packs one is 3A, an other one is 5A and one is 8A discharge capable.

Thanks! My future plan is to somehow incorporate the battery and electronics into the previous PF battery box as well.
