I got the charger today from Amazon. Looks like it has a lot of capabilities. There will be a learning curve. My first disappointment was that there was no connector for my H107c. Where can I get one? Plus another battery question. I have using the charger that came with the H107c and a cheap charger that can do up to 6 batteries at a time. Is there a way to tell if a battery is shot. In other words can no longer take a charge? Thanks in advance.
