    I had an absolutely EXCELLENT experience hiring LITHIUM LLC to do my 200amp electrical panel upgrade. The owner 'Brent' is a pleasure to work with - honest, ethical, on time and true to his word. His prices are also the best in town. I had bids from $4k up to 16k for the exact same job from 8 different local electrical companies that I got quotes from. He also encouraged me to save money by pulling the $1400 city permit myself - which I was able to do all online. He expertly guided me through the whole process and I couldn't be happier with the end result. And his stucco 'finish work' around m

    Brent did an amazing job replacing my electrical panel and installing a sub panel. He is friendly, knowledgeable, professional, and he went above and beyond in every aspect of the job. I highly recommend Lithium!

    Highly recommended for anyone looking for a reliable and knowledgeable electrician. I’ll definitely be calling them again for future work.

What reviewers keep mentioning

  • punctuality 2
  • electrical panel upgrade 2

Topics Google derives from the review text, with how often each appears. A frequent topic is not a good one: “price” turns up in praise and in complaints alike.

What the company says about itself

Taken from its own website. We have not checked any of it, and a sentence on a website is not evidence.

  • 24/7 availability

    “& businesses with lower energy costs 24/7 Support Our team is available all the…”

Its website also mentions free estimate, but not in a sentence we can quote cleanly.

  • It posts on Instagram and X. A page that stopped posting years ago tells you something a listing will not.

Ordered by how much we can tell you about each, which is not an order of quality. We do not know which of these is better and would not say if we did.

What we don't know

  • The date above is the newest review we hold, which is not necessarily the newest that exists — we hold a large share of Google's reviews, not all of them.
  • Google publishes no street address for this company, so we cannot say which town it is based in. Yucaipa is the area its listing was returned for, not an address we hold.
  • We do not verify licences, insurance or bonding. Nothing here has been checked against a state licensing board.
  • We cannot tell you what an installation costs, and we hold nothing about the equipment they fit.
