I've just made my $8 lithium transmitter battery pack following Bruce's excellent guide. It works fine but I have a question about charging it. I'm using the Accucel 6 4 button balance charger, which I haven't used before. If I use the Lipo setting to charge it with a charging current of say 1 amp and a voltage of 7.4 volts, after a minute or so the charger beeps and gives a "battery disconnect" error. I've played around with the settings and if I drop the charging current down, to say 0.1 or 0.2 amps, I don't get the error but the charging times out (safety timer is set to 120 minutes).
It seems like these betteries don't like it when the charging voltage gets too far above the 7.4 volts which seems to happen with the high current setting. Is this because of the built-in over-voltage protection that Bruce talks about in the guide?
What's the best way to charge these things - quickly?
