Roo,

I have absolutely no concrete evidence to back up my claim but, here is what I think I've found.

I had a hangar 9 double vision charger that i've used for years. I traded my father for his Accu-cycle Elite since he didn't want to fuss with the additional doo-dads and buttons. The Double Vision is almost plug and charge. soon afterward, I started to feel that my batteries were not giving me the same amount of use and I felt that after a couple of years, they might be going bad. I didn't think this was a problem as many gave me years of service. I went out and purchased two new batteries (6v and 4.8v, both 2700 mah) and a new Tx battery (1500 mah). Even the new batteries didn't give me the service I was expecting. After a few flights, they were down to 4.7 or 4.8, lower than I care to fly with, especially if they're dropping that fast.

Well, I borrowed dad's Double Vision and started using that to charge the batteries. I'm finding (again, with no concrete evidence, I admit) that the batteries are lasting longer. Now I'm getting an entire day of flying with them and they're still at 5.0 or close to that. I'm at the point now where I'm planning on buying my own Double Vision. It's a fraction of the cost and, in my opinion, it does a better job. It just doesn't have all the bells and whistles. but, at the end of the day, if you're not happy with how the charger charges the batteries, what's it worth? Just my two cents and like I said, only my perception. Take it for what you will.
