Trojan TR-48-170-M Lithium OnePack XR - 48V 171Ah Golf Cart Battery | 75 Mile Range

Trojan TR-48-170-M Lithium OnePack™ Extended Range (XR) - 48V 171Ah LiFePO4

75 Miles Per Charge. One Battery. Zero Maintenance.

The Trojan TR-48-170-M Lithium OnePack™ Extended Range (XR) revolutionizes 48V vehicle performance with a single lithium battery that delivers up to 75 miles per charge—nearly 30 miles further than standard lithium alternatives. This drop-in replacement eliminates the complexity and maintenance of traditional lead-acid battery banks while dramatically reducing weight and maximizing range.

The Ultimate Single-Battery Solution

Replace an entire 6-8 battery lead-acid bank with one advanced lithium battery. No more checking water levels, cleaning corroded terminals, or managing acid—just pure, reliable power that lasts for over a decade.

Ideal Applications

Golf Carts - Extended Range Perfect for golf courses with long, hilly layouts where standard batteries fall short. Powers 18 holes with energy to spare, even with aftermarket accessories and challenging terrain.

Large Multi-Passenger Vehicles Specifically engineered for 6-8 passenger golf carts and shuttle vehicles that carry heavy loads. Provides the extra capacity needed for commercial resort operations, retirement communities, and campus transportation.

Low-Speed Electric Vehicles (LSEVs) Drop-in upgrade for neighborhood electric vehicles requiring extended range for daily commuting and errands without range anxiety.

Commercial Utility Vehicles Powers commercial fleet operations with all-day reliability. Ideal for maintenance crews, security patrols, and property management vehicles operating on large campuses or facilities.

Hilly Terrain Operations Delivers consistent power on steep inclines without the voltage sag experienced with lead-acid batteries. Maintains performance regardless of terrain or load.

Performance Advantages

Extended Range - 75 Miles Per Charge Nearly 30 miles further than standard 105Ah lithium batteries. Complete even the longest routes without mid-day recharging or range anxiety.

Massive Weight Reduction At just 170 lbs, replaces 300-500 lbs of lead-acid batteries—improving vehicle handling, reducing tire wear, and increasing payload capacity.

True Drop-In Replacement Designed to fit standard 48V golf cart battery compartments. No vehicle modifications, no special mounting hardware—simply install and go.

Opportunity Charging Charge anytime, anywhere, for any duration without damaging battery life. Top off during lunch breaks, between shifts, or overnight—lithium doesn't care about partial charging.

Consistent Power Delivery Maintains full voltage throughout discharge cycle. Unlike lead-acid batteries that lose power as they drain, lithium delivers consistent performance from 100% to empty.

Why Lithium Iron Phosphate (LiFePO4)?

Safest Lithium Chemistry: Unlike other lithium chemistries (NMC, NCA), LiFePO4 is inherently stable and won't experience thermal runaway. It's the chemistry of choice for golf carts, marine, and RV applications.

Longest Lifespan: 2,000-3,000 cycles at 80% depth of discharge means 10 years of daily use—2-3x longer than other lithium chemistries and 3-4x longer than lead-acid.

Best Temperature Performance: Functions reliably in extreme heat and cold where other chemistries fail or require heating/cooling systems.

Most Environmentally Friendly: No cobalt, no toxic materials, fully recyclable. Better for the environment than both lead-acid and other lithium chemistries.
