Brown Recluse Module

Features

  • Passive cooling system designed to maximize local and overall heat transfer coefficient
  • Modular design can be integrated into multiple vehicle types and system configurations across voltage and capacity ranges
  • Rapid charge/discharge coupled with integrated BMS (battery management system) for higher performance
  • Patented e-plate technology for cylindrical cell connections + cost effective manufacturing for flexible module sizing with minimal tooling
  • Combine additional modules in series or parallel for greater total kWh capacity

Cycles and life

  • Power cell: 1,500 charges
  • Energy cell: 4,000+ charges

(Cycle life and calendar life are very much application dependent. A more application-specific analysis can be provided.)
