Help Tucker Get New Batteries for His Chair

Hello, my name is Dan. I am raising funds for my 9-year-old son, Tucker. Tucker has Duchenne Muscular Dystrophy and lost his ability to walk in December. We scraped together money for a cheap power chair, and it is falling apart and does not fit him appropriately. Another family donated a nice power chair to us, but the batteries are bad and won't take a charge. I need to buy 2 new batteries so he can safely get around and live life.
