I think I cracked the code for charging the SPMB6000LITX 6000 mAh LiIon battery out of the transmitter. After reading the specs on the charger doc that accompanies the battery on the Spektrum site, I deduced that any old 5V 2A charger would probably work. So I set my benchtop power supply for 5V and 2.0 amps and built a harness with pins so I could connect to the battery. I could feel there’s some kind of PCB inside the pack’s heat shrink wrap and guessed that was the charging monitor. After about 1.5 hours, the battery’s internal charging monitor automatically shut off the charging current from the power supply. I put the battery back in the transmitter and voila, it was fully charged at 4.1 volts.

Why did I do it? Because the micro USB port on my NX10 is broken, and I needed to use it for a pattern meet before shipping the transmitter in for repairs.
