I read about the slow charging thing here: http://www.powerstream.com/li.htm

"When the charge rate during the constant current phase is low, the charger process will spend less time during the constant voltage tail. If you charge below about 0.18 C, the cell is virtually full when the 4.2 volts is reached. This can be used as an alternative charge algorithm. Just charge below 0.18C constant current and terminate the charge when the voltage reaches 4.2 volts per cell."

As for the amp, I have this one: https://hifimediy.com/T3-mono

I also put together a preamp of sorts, a piece of stripboard with an active Baxandall tone control circuit and a high pass filter to filter out deep bass
