We founded Tewaycell with one goal in mind: providing a high-quality, smart, and reliable energy storage solutions for people worldwide. We are famaily, we are all living on earth!

Our passion for helping people to store energy, save money while also preserving the environment drives us to develop and sale emerging products.

One way we can achieve this is through helping people build their own Off Grid Battery banks with LiFePO4 Batteries and accessories.

Marvel has Iron Man. Tesla has Elon Musk. We have Jacky Lin.

Unlike most of us, we have been obsessed with electricity since childhood. He studied batteries until he graduated from university and finally became a battery engineer As an engineer, he’s racked up over 20 years of experience developing groundbreaking ionic lithium battery technology, collecting a plethora of patents related to lithium battery management systems along the way. It’s how he fell in love with power (in a good way). But there were things he didn’t love. Like all the unanswered questions...

                                                                                                                                                                        Why are lithium batteries so expensive? The numbers didn’t add up.

                                                                                                                                                                        Why don’t they add the ability to check your battery status from your phone? We have the technology, after all.

                                                                                                                                                                        Why do people still buy lead acid batteries?

Lithium was (and is) superior in every way, including cost, especially long term. So he set out to answer those questions (using first principles thinking, of course). A thorough believer in “actions speak louder than words,” he created Tewaycell battery brand. Thanks to his vision, the company is now helping the world revolutionize energy storage, develop planet-safe power, and play harder and longer. Because better batteries mean better, bigger, and longer adventures. Founded in 2007, Tewaycell has become a worldwide leader in the field of LiFePO4 batteries, because of a clear vision and top shelf products that won’t wring your wallet dry.

Tewaycell batteries are built tough, from materials you can count on. But great quality is just the beginning. We’re constantly chasing after innovative ways to make our batteries safer, smarter, and more efficient.

As the creator of the Ionic brand of lithium batteries, we’re proud to be on the cutting edge of technology. Ionic lithium batteries are lighter, safer, and longer lasting than traditional batteries (as well as other deep cycle lithium batteries on the market). Our other brands mirror that quality, thanks to the team’s rigid standards.

We’ve also added incredible features like Bluetooth technology. With the help of a handy app, you can check on your battery’s vitals any time. No more worrying about how much power is left, or how much longer your battery will take to charge.

Like a sturdy bass boat or RV, our products are built to take you where you want to go, and stay with you for the long haul. Speaking of boats and RVs, we specialize in batteries that not only power them, but enhance their performance. Our LiFePO4 lithium batteries revamp scooters, solar setups, boats, RVs, commercial applications, and more.

We’ve also expanded our offerings to include problem-solving products like the Emergency Start. This permanently-mounted jumpstarter is the first of its kind. It can jump dead batteries in cars, trucks, SUVs, boats, UTVs, and more.

Of course, each adventure-seeker’s needs vary. That’s why we’re constantly adding new products to enhance your journey, wherever it may take you. Under “Accessories'', you can find portable solar setups, hunting/fishing clothing, and battery extras, such as terminal adaptors and battery trays.
