€250-750 EUR

Paid on delivery
We need someone to design, layout pcb, circuit design and create schematics for a Li-Po balancer-charger based on an IC like Linear LTC4015. The batteries that needs to be charged (and balanced) are Thunderpower TP7000-6SHV (max voltage 6x4.35V=26.1V) Max current output should be 14A, min 10A Input power source will be selected based on balancer needs Over-current protection PCB dimension and weight should be as little as possible Charger telemetry should be available over i2c or UART

Hi, I will use eagle for this project. We can refer to LTC application note and design guide to make this board work propperly. I didn't read it yet now, but we can discuss it again over messenger. For critical Circuit like this balancer , we have to consider the components layout, as well as thermal distribution, 10A input isn't small Value. so, I will make some point of circuit to be exposed from soldermask to enable PCB engineer to add more soldering paste to it . we can discuss more about it. I have became pcb designer since 2012 and I have successfully designed critical PCB like Switching power supply,on board RF PCB antenna, high speed digital communication, differential pair, BGA fan out, and many more. as long as there are propper design guide from manufacturer, we can go on. it will be better if there is available evaluation board that we can copy it's layout. let's discuss this project furthermore over messenger. let me help you design it. Best Regards, Rijal

Hi Sr, I can design the circuit that you need. I will design the circuit using Altium Designer, first I will make the schematics with the BOM and then I will design the PCB. The PCB will be designed using 3D libraries for you can see the Board before to send it to manufacture. I will give you complete package with all the necessary files to manufacture the board: Gerbes, BOM, Altium project files and 3D files. I'm electronic engineer with more than 15 years of experience and know how to make this design and the necessary precautions to take in count with this type of batteries. Please visit my portfolio to see my last jobs and more references. Any question, please feel free to contact me. Best regards. Eng. Juan M Garin

Hi, I can make the balancer board PCB for you using LTC IC for 6 cells of the battery. I can make a balancer board which you can use to balance the 6 series batteries while charging and discharging with all the protections you mentioned in the description. Please let me know if you have any specific requirement of board size, board layers, Specific balancer IC or components or I am free to use whichever available with me. Please tell me if it suits you and we will discuss more in detail. Thanks, Viral
