Question 1

Will this quickly charge the Smart Controller without giving the slow charging error message?

Accepted Answer

This is an awesome smart charger.  It charges up to four batteries and the controller simultaneously, and it communicates with each battery and each batterie's internal cells to make sure that each cell in each battery is properly balanced for the best possible flight duration.  I am averaging more than 29 minutes of flight time per charged battery, and I actually achieved almost 40 minutes in a hover at 245' AGL, recording lightening strikes in a distant super cell thunder storm, awesome! In addition it also can be used in reverse to properly discharge batteries and each cell in a balanced fashion for long term battery storage.  I have not had any errors of any kind  when charging the batteries and/or controller.  Understand this is not a fast charger because it is charging all the batteries slowly and properly like it should which will extend the life of each battery.  What I do is I fly by day, and let the charger do its thing and charge everything perfectly over night.  It also has a nice display on top that lets you know what the charger is doing as it is doing it with each battery and each cell, as well as the current battery level voltage for each battery and cell.  You just attach the batteries, plug it in, and walk away. I have three of these chargers.  One final note, this charger does what my 300 plus dollar computer controlled Battery charger does, that I have used for years with all my old smart Lipo batteries on all my home built drones and fixed wing aircraft for a fraction of the price.  Buy it, and use it.

Question 2

Does this charger get very warm, or even hot, while charging multiple batteries?

Accepted Answer

If anyone says it does, then they must have a defective unit. My unit doesn't even get warm because the fan does an excellent job in keeping the charger cool.

Question 3

While battery is plugged the letters in-l are flashing and battery is not charging. is the charger malfunctioning? please help.

Accepted Answer

After the battery is fully charged it just blinks green  while it cycles  through all the slots while flashing “checking”

Question 4

Can someone provide me with customer service contact information — having trouble finding it, for some reason.
