Hi,
I have done Bachelor in Mechatronics and Masters in Industrial Engineering. I am Solidworks Certified Professional in Mechanical Design and currently working as Product Development Engineer. I can get battery developed according to your requirements and can provide you 2-3 reliable sources with quotations. You can get prototypes delivered to you from all potential suppliers, testing for quality and specifications then order for mass production directly or through me, whichever is easy for you.
For reference, view my profile, portfolio and project history.
Regards,
Muhammad Salman Mughal
