built better. protected better made to last
Mad Scientist batteries are handmade in Mississippi using premium EVE Grade A LiFePO₄ prismatic cells—one of the safest, most dependable lithium battery chemistries available. Every battery is carefully assembled, top-balanced, and equipped with a premium JBD Bluetooth BMS for dependable protection, real-time monitoring, and outstanding performance.
What truly sets our marine batteries apart is our patent-pending flooded lithium technology. The internal components are surrounded by a proprietary nonconductive dielectric fluid that helps prevent moisture intrusion and protects the battery in harsh marine environments.
Premium cells. Advanced BMS protection. Innovative moisture protection. That’s the Mad Scientist difference.
