I'm from (don't hate me) the USA. I'm looking to get more range, so I can actually go someplace. Found this site this evening and like what I saw. I'm disabled and have not much money. That BM3 is the chair I've been looking for for years. You're right. NO ONE MAKES THEM! What they do make is outrageously expensive for what ya get. Can't afford a car and insurance; live in Michigan state, so my chair is my main tranportation. Two days ago found myself sitting in 50 degree weather F. waiting for a bus for an hour and still had to get a push from a neighbor to get up my ramp at my apartment. I have a cirrus EC plus. Any way to adapt it to your style batteries? Not available commercially that I've been able to find. One other question: what is the cost range for what you've developed? I live off disability payments so I have little extra cash.
Thanks for listening and, again, HI.
