Built Different. Built Better.
New Technology.Serious Performance.
Custom Lithium Batteries by the Mad Scientist was founded on one idea: batteries should be engineered, not just assembled. Too many people were stuck with heavy, short-lived lead-acid packs — so we set out to build something dramatically better.
We build high-performance LiFePO₄ (LFP) batteries for the things that matter most. Stronger, safer, longer lasting. Every pack is custom-built from premium cells with smart BMS protection and clean, professional assembly — right here in the USA.
From golf carts and bass boats to forklifts and off-grid solar banks, we engineer more power, more range and more reliability into every battery we make. That is the Mad Scientist difference.
What Sets Us Apart
Four things we refuse to compromise on — no matter what we are building.
Engineered, Not Assembled
Every pack is designed around how you actually use it — the right cells, the right BMS, the right build.
Premium Cells & Smart BMS
We start with premium-grade LiFePO₄ cells and protect them with smart battery management for safety and longevity.
Proudly Built In The USA
Designed, assembled and tested by hand in Flora, Mississippi — with quality you can count on.
Backed By 8 Years
We stand behind our work with an 8-year warranty because our batteries are built to outlast the competition.
