Hi All,
New to RC cars. I brought a second hand flysky nb4 which didn't come with the battery bank, little did I know I need that for charging and firmware update.
I am trying to see whether I can connect the USB directly to the 4 pins at the bottom. I could see the ground (4th pin when you look from screw side is directly connected to ground of battery, tested with connectivity checker) but the positive is not directly connected to battery so I am fairly confident the charging module is part of the controller and not on the battery bank.
I am just wondering whether it passes 3.5V or 5V from the battery bank to these pins.
Is any one able to put a multimeter to their battery bank on the two extreme pins and say what volts it shows up (I don't have the battery bank so I can't say) Thanks in advance!
