Our Focus
Wiltson Energy designs and manufactures low-temperature LiFePO4 battery packs for OEM and ODM partners who need reliable power in extreme cold — without relying on internal heaters that waste energy and add failure points.
Our packs are built for cold-chain logistics, arctic and outdoor solar, telecom and industrial robotics, and other environments where standard lithium iron phosphate chemistry falls short. The goal is simple: charge and discharge at the temperatures your sites actually see, with performance that can be independently verified.
We invest in cold-temperature cell chemistry, pack design, and BMS software so that heater-free operation is an engineered outcome — not a marketing claim. Intellectual property around low-temperature BMS and pack design supports that focus; we do not list unverified patent numbers on this page.
