Voltrium

Voltrium sells high-voltage lithium-ion battery packs, chargers, and related accessories for personal electric vehicles—primarily e-motorcycles, e-bikes, and go-karts. Product lines span 48 V to 120 V packs rated 20–100 Ah, priced USD 599–1,899, placing the brand in the mid-to-premium tier. Sales are direct-to-consumer through voltrium.com with global shipping; no brick-and-mortar network is listed. The company positions itself on “race-grade” energy density—up to 260 Wh/kg in its UltraPacks—and a modular, connector-free slide-in architecture that lets riders series-link up to 4 packs without external harnesses. Every battery ships with an IP67-rated aluminum case, active BMS, and Bluetooth telemetry that logs cell-level data to a mobile app. These features have made the 72 V 50 Ah UltraPack a staple in competitive e-moto circuits. Customers are DIY converters, amateur racers, and light EV builders who value performance per kilogram over lowest cost. They tend to modify Sur-Ron, Talaria, or custom frames and prioritize tunable power curves, rapid 3C charging, and verified cycle life (>1,000 @ 80 % DOD) for track days or trail riding. Voltrium competes with mass-market Chinese pack suppliers and boutique North-American battery ateliers. It differentiates by combining aerospace-grade 21700 cells, in-house spot-welded busbars, and firmware that auto-detects motor-controller voltage, eliminating the need for external step-down converters or balance leads.
