Feedback of VBA-V3 and ESP32-WROOM

Hi Tina,
All three boards have now been tested at full current. 30 amps out at 20V, driven by a 12V battery (that dropped below 12V during the test) at just over 60 amps.
Everything seems to be working as hoped for. We will mount them is a metal box and use thermal potting as heat sink on the MOSFETs while the load is high. At 15 amps output, it requires no cooling. A success!
The break-out boards are also very nice. Well made…
Thanks for your help in getting these prototype boards made. We will definitely be back!!!

P.S. What is your real (Chinese) name? I know you use an English name for English customers…

Thanks for your help

Jason,

I have found an issue with the design, the design did indeed short circuit. Thanks for your help. We will have to get new prototypes produced.  Regards|Kyle Handfield|Managing Director

Please thank your team

Hi Zoey,

Thanks so much. Please thank your team as well. We really appreciate the work you’ve put in to help us out with these boards :)–Cheers—Tim Hadwen/Co-Founder / Hardware Lead

Great Work of Battery Pack PCB Assembly

Hi Bella,

I checked the 30 unit and they are exactly how we would expect them.

Great work, the battery is well soldered, the main connector too and there are no missing screws.

Keep up the good work!

Thanks,

Thanks!

Hi Jason and Kira,

Thanks for the last couple days. You took a lot of time to drive me around and get stuff done. I like the way you guys work and get things done – it is a lot like how I do things. Working in the hotel room, I have done that at so many trade shows. Good times.

But thanks. And you sure have great guys at your factory. That Xie guy is good stuff.

Look forward to our next meeting.

I appreciate your trust!

Hi Carl, Me too, I appreciate your trust! And you give me a great help (for example with the project Microchip which without you could not be a success!) And I feel the whole heart that has been put by everyone in the work that I receive. This is very important for me because I work in the same way. And I have trouble seeing this world that is content to see humans as objects. Thank you very much!

Quality exceed exception

Hi Zoey
thank you a lot for your mail.We are very happy with the board.We already tested 10 boards and programmed them. They are fully functional and do exactly what we have expected.For our next project we will come back to you. I have already recommended your company to some of my colleagues and business partners.

Best

Great service!

Speed, quality, and great service, WellerPCB has allowed us to move quickly on development and not stress out so much about inevitable board goof ups that previous have cost us weeks.
