I agree it seems to be working. Thanks for saying you use the SP4500....I must have missed that. Do you top the batteries off with the DJI charger after the SP4500? A lot of people seem to be doing that.I still use the Smart Power Charger SP4500 to charge my batteries. I only use the ICharger 106B for discharging my Inspire bats besides my lipos for my homebuilt crafts. I am using this power supply NES-350-12 - Mean Well - TRC Electronics. It may not seem like this system should work but I have the proof that it does.
