Trojan's OnePack Extended Range (XR) TR-48-170-M delivers revolutionary lithium iron phosphate (LiFePO4) technology in a high-capacity 48V 171Ah battery pack engineered specifically for extended-range electric vehicles requiring maximum distance per charge, zero maintenance, and a single drop-in replacement for traditional lead-acid battery banks. This game-changing upgrade delivers up to 75 miles per charge—nearly 30 miles further than standard 105Ah lithium batteries—making it perfect for golf courses with long, hilly layouts, large multi-passenger vehicles, and commercial fleet operations requiring all-day reliability without range anxiety. At just 170 lbs, the OnePack XR replaces 300-500 lbs of lead-acid batteries (6-8 battery banks)—improving vehicle handling, reducing tire wear, and increasing payload capacity. The smart Battery Management System (BMS) provides four levels of safety protection continuously monitoring against overcharge, over-discharge, short circuit, and temperature extremes, while integrated Bluetooth connectivity enables real-time tracking via the free Trojan SmartBattery App for monitoring battery status, state of charge, voltage, current, temperature, and cycle count from a mobile device. Operating from -40°F to 140°F with IP65 water and dust protection, rapid charging in 4-6 hours (2-3 hours with fast charger), and opportunity charging capability without damage, the OnePack XR is completely maintenance-free—no watering, no terminal cleaning, no acid—and delivers 2,000-3,000 cycles at 80% depth of discharge, meaning 10 years of daily use. As a true drop-in replacement designed to fit standard 48V golf cart battery compartments with no vehicle modifications required, backed by a 10-year warranty and designed, tested, and final-processed in the U.S., the OnePack XR TR-48-170-M delivers consistent power throughout the discharge cycle for golf carts, multi-passenger vehicles, LSEVs, commercial utility vehicles, hilly terrain operations, and floor scrubbers requiring extended range and professional-grade reliability.
