Winter Performance Series

When temperatures drop, lithium-ion chemistry slows. The result is simple: Resistance increases → sag increases → power drops → usable capacity drops. That’s why winter batteries need more than “higher Ah.” They need low resistance design, robust current paths, and electronics that protect the pack when conditions are harsh.

Tabless architecture reduces bottlenecks inside the cell. That means: Shorter current pathways Lower heat concentration under load More stable voltage delivery when you demand power in cold air Our Winter-Ready lineup includes tabless cell options and low-resistance builds specifically chosen for real-world cold riding.

Pure Copper Busbars (not nickel) High-power winter riding punishes weak current paths. We build with pure copper busbars to reduce resistance and improve high-current delivery — which helps combat cold-weather sag and supports demanding motors more safely. Double-Layer Encasement Protection Winter riding is messy: salt, spray, slush, grit, vibration. Our packs prioritize several layers of protection: Structural housing + mounting interface (rigidity + impact defense) Secondary internal shielding and pack protection to help defend the cell pack and electronics from vibration, dust/splash exposure, and seasonal abuse U.S.-Made, Precision Built in Bethlehem, PA Every pack is built in-house — not overseas — so you get verified premium components, consistent assembly standards, and real support when you need it.

Before Reliance RS50, Molicel dominated the marketplace with their tabless cells. The results are in, read the data confirming Reliance is now the rising star in premium, high-current battery power.
