Open the seat and confirm six 12V batteries before ordering — a 48V Freedom TXT uses a different kit, and factory ELiTE lithium carts are not covered. Controller Compatibility The 72V Freedom TXT uses an E-Z-GO 350A AC controller. The Fleet Lithium 76.8V pack is fully compatible — no reprogramming, no controller upgrade, and no wiring changes. Aftermarket controllers should be verified separately. Will this fit my Freedom TXT? Yes, on 72V lead-acid Freedom TXT carts from 2017 through 2021. No vehicle modification is expected with BR5900 and the Fleet 72V lithium charger. Does it fit a 48V Freedom TXT? No. The 48V Freedom TXT uses a different pack voltage and charger. Use the vehicle finder to confirm your system voltage before ordering. How long does installation take? 30–60 minutes with basic hand tools. Does it work in cold weather? Yes. The built-in heater activates automatically below 32°F — standard on every pack. *Range estimates are maximums under ideal conditions (flat terrain, single rider, 12–15 mph, 70°F). Actual range varies with terrain, weight, speed, and temperature.
