Old man scooter batteryReviewsLithium iron phosphate 24V 42AHThe wheelchair can run for 30 minutes with the original lead-acid battery, and can only be upgraded with lithium battery. After many times of communicating battery parameters and battery cell parameters with different businesses, I finally chose this lithium battery. In order to satisfy the elderly, I measured the battery life for several days. Outdoor temperature 12-14 degrees, load 165 kg, motor 250wx2, speed 6km/h, full charge indicates 100% capacity, the first day of running for 2 hours about 8.5km, the remaining power is 75%, the voltage drops to 27.5v, the second day After running for 75 minutes, about 6km, the capacity dropped to 50%, and the voltage dropped to 26.5v. The third day ran for 2 hours about 11km, the capacity dropped to 25%, and the voltage dropped to 25.3v. The fourth day ran for 2.5 hours. At 14km, the red light just turned on, and the voltage dropped to 23.4v. Calculating the battery life is 7 hours, 39.5km, and the cut-off voltage is not reached yet, it seems that running 40km is definitely no problem. The next step is to look at the battery life. The merchant has a two-year warranty. After two years, the battery capacity will reach 80%. It can also meet the needs of the elderly. Don't worry about pushing the wheelchair home on the way.▲ Notes1. [Size] Due to manual measurement, please allow 1-3cm / 0.39-0.79 inch differences in measurement.2.
