Experience a professional-grade lithium upgrade with the Bolt Energy 51V 105Ah Heated Thin Lithium Professional Conversion Kit. Designed for high-demand electric utility vehicles, this advanced lithium system replaces heavy lead-acid batteries with a powerful, space-efficient LiFePO4 solution that delivers longer run times, stronger performance, and significantly faster charging. Built with premium prismatic lithium cells and an intelligent Battery Management System (BMS), the system provides consistent power delivery, improved efficiency, and long-term durability for both work and recreational use.

The kit features Bolt’s slim battery design, maximizing available space while maintaining a full 105Ah capacity. The lightweight yet rugged powder-coated steel enclosure with IP66 protection ensures durability in harsh environments, while Bluetooth connectivity and the included Smart SOC meter allow you to easily monitor battery performance and charge levels in real time.

A key advantage of this system is its integrated self-heating technology, allowing the battery to safely charge in colder conditions. When temperatures fall below the optimal charging range, the battery automatically warms itself while plugged in. Once the internal temperature reaches approximately 34°F, normal charging begins and the heating system shuts off automatically. This intelligent system allows the battery to charge in unheated garages, barns, or outdoor environments, making overnight charging reliable even in cold climates.

This Professional Conversion Kit also includes premium installation components such as a 400A solenoid, heavy-duty 2AWG cables, and a 30-amp reducer, making it a comprehensive upgrade solution designed for performance, reliability, and simplified installation.
