Re: rode all day in snow brought inside to charge now...
I would take the motor controller out, remove the end cap without wire on it and smell the insides. If it smells burned, you need to take out the other 5 screws and see what smoked. In mine, I had corrosion and Q5 was missing 25% of the package. I cleaned the corrosion with a old tooth brush and 99.9% alcohol that I had. Replaced the part and all was fine. There is a trick to installing the bracket that holds Q5 and D11 to the case (a heatsink). I put the board and wires in the case and secured with 4 screws. I put the assembly in a vise with the side hole on the bottom. Align the bracket with the outside hole on top of Q5 and D11 (use a small wire that goes thru both holes) I took an x-acto blade- a flat one and slid it on top of the bracket that is now laying on top of Q5 and D11. By pulling up slightly you can put pressure on the bracket holding it in place. Insert the retaining screw and other end cap.

Same thing started happening to me. The red charging light was initially going out but then after a few days use started staying on. I assumed that the battery was damaged and bought 3 new batteries but the red light is still staying on when I charge the new batteries.
I suspect that the mains charger I was using (same voltage but not the recommended charger) has perhaps damaged a component inside the EFLC1003 unit which is now not letting the power through to charge the battery.
Undercharging. Make sure to charge until light on charging unit is fully bright. If the light on the charger gets ANY brighter when you unplug the helicopter, then it's not fully charged. Note that if you are using a usb charger, that most laptop usb ports and front side desktop data ports are not fully powered to the required 5volts DC, and so can take several hours to fully charge the battery.
Over-discharging. Once you cannot maintain altitude, land helicopter and power it off. Draining a Li/Po battery fully, or even close to it, will weaken it's ability to hold a charge, and can ruin it entirely. Not like the old Ni/Cad rechargeable batteries. Improper care. Batteries should be allowed to cool for 10 minutes after every flight, and 10 minutes after every charge. Like over-discharging, overheating will always weaken, and can destroy your Li/Po battery.
How do you know it's the pedal. The reason I ask is that I'm having the same problem and took the cover of underneath the pedal to try it manually and had no luck. I think the problem may be elsewhere with one of the other wires. In the past I have had problems with it only working in Hi speed and realized one of the wires had come loos at the connector. I brought it up after spending the winter in the basement and it worked fine the first time around. Then I turned it over to fix a problem with the solder coming loose on the front steering and after that I'm not able to get it to work as there is no power going to the wheels. Intermittently I will get power but not on a consistent basis. I don't think it's a battery charge issue, but a loose contact from when I had it turned upside dow
I had a similar problem. When scooter purchased, gave it the full 8 hr charge. Was great. Husband did not bring batteries n that winter from unheated building. If left in cold a trickle charger needs to be on it. Easier to take out and bring in.
Same thing happened. Would charge and said fully charged but one battery(has 2) had a dead cell from being out in the cold. Took to batteries plus(very reasonable) had it checked and purchased.new one. Put in and gave it a full charge. Wonderful ever since. Use it at horse shows to run from trailer to stalls to arena and all over. Constantly forget to turn switch off and still comes through for me. It appears to go into a sleep mode when you forget to switch off. When back to trailer to sleep plug it in. The first 2 days of a 7 day circuit didn't plug in but then started to whenever I took it back to trailer as the strip sign says on platform. Duh!! Love it, love it love it!!!
I have purchased 2 remote controlled toy cars from Costco over the years. These New Bright batteris and charges last only a few charges, and then they go bad. I am disappointed. I will go to Walmart and buy a new battery and see if it works better, if not, i will return to Walmart.
