Dear potential candidate,

We are in search for an experienced engineer to build us a working solar lithium ion battery charger.

For this project we will be using a DC 25-30V-3A solar panel to charge a lithium ion battery with DC 19V-5.5A. So we need a custom charge controller built specially designed for safe lithium ion charging with solar panel. If you think you are the right expert for this task please write to us your experience and why you think you will be the right person for the job. Thank you for your interest.
