Whats LFP stand for?Hi Sch,
Your experience matches what I got, 14 miles per charge on rough trails with new lead acid batteries. I bought my Ranger from an online auction. It was from a rental fleet. Beat up with 375 hours with a new set of USA FLA batteries. I never got 30 miles per charge but I did not try a long trip on pavement with 30 psi. I switched to an 10.5kWh Atlas ESS LFP battery. I found my consumption on rough trails was approx 295 watt/hr per mile, with 7psi in the tires. So my range is 36 miles per charge. Range will increase with higher tire pressure and better trails (less rolling resistance). Also, the personality of the Ranger changes when you loose 460 pounds of lead! You should definitely change to LFP.
