Hi, I have developed before power bank with 18650 batteries for 5V output. I can design your board and prepare 2 prototypes and send to you. All the BEST, Ali SERBETCI

Hello, I am Anthony from Sri lanka. We are a hardware designing & prototyping company. Why you should hire me ? - I have seven years of experience in the field and have developed many battery monitoring systems. - I have state of the art testing lab and PCB fabrication workshop. (I know you dont need fabrication) - I have many contacts in China. I can help you with mass producing this. Please contact me if you are interested. Thank you Anthony

Sir, I am an experienced electronics engineer in a leading electronics company. I developed so many Embedded boards, FPGA boards, SoC boards, Microcontroller boards using ORCAD Cadence and written codes in C, VHDL, Vivado. Please give more details about your logic and requirement. I will make the schematic, BOM, PCB layout, Gerber. Thanks

Hi, I am kahan. I am electronic engineer and have much experienced in circuit designing and debugging. Waiting for further discussion. Thank you.

Hello Hope you are doing great. I am an Electrical Engineer and have vast experience in making power electronics circuits. If you are interested then we can discuss details over chat. Regards

Hi, I can design power supply circuit for you professionally at affordable price. Revisions till 100% satisfaction. I have positive feedback, reviews and 100% completion rate from my previous clients because of the great quality of my work and affordable price. So please send me a private message to discuss more or to start right now. Looking forward to your message. Regards, Tariq Mehmood Khan.

I have studied mechatronics engineering so I can design circuits very easily. Moreover I'll complete work in time and also available 24/7.

Having 7years of experience in Circuits design and development.

I work in Altium and have experience (full-time job) in designing digital, analog electronics, power supplies (including USB power distribution and USC C compliant power banks). I would keep you up-to-date during whole schematic and PCB development (would provide you with schematic, 2D and 3D drawings of the module). I would provide you with whole assembly documentation (PCB gerbers, BOM, assembly drawings, schematic, pick 'n' place files...). If we agree so, I can also provide prototype assembly and verification. Quality and conscious work is guaranteed.

All 3 voltage rails must be independently stabilized? remaining battery level reporting & US$3.50 components => looks like fantasy... low level indication - nearly to reality...
