Hi all,
I have received a Syma x5c quadcopter (used from a brother), he had purchased 4 extra batteries along with this quadcopter. The batteries are "3.7V 600mAh." Along with the batteries is a 4-in-1 charger that can be plugged in via USB or wall plug adapter.
After flying the other day, my quadcopter began to slow down. I landed in front of me and checked the battery, which was fine. I tried to take off again and the motor didn't work. The motor had been burnt out. I purchased 4 new motors that were made for this particular model of quad and replaced the burnt motor. This may be where the problem lies but I highly doubt it.
The day the quad had burnt out, I plugged the batteries into the wall (4 of them) and left for dinner (and some activities with the family). They charged for maybe 5-6 hours, when I returned home later. I unplugged them since all the indicators were off, and they were complete.
Yesterday, I repaired the quad and it flew just fine! The only problem was the battery indicator light on my controller started flashing immediately- with a freshly charged battery. The quad flew very well for maybe 30 seconds, and then without hesitation began flying around 5-10 feet off the ground. It was very slow to ascend (although the turning was perfectly OK) and was very lethargic to my throttle control.
My question is, is it possible they were overcharged? They were on the charger for longer than they needed to be, but according to other resources, I was told they should stop charging immediately when they reach their limit. Is it possible I messed something up on the inside when repairing the motor? I didn't move anything around, I spliced the motor onto the old motor wires. All 4 batteries that were charged on the charger do the same thing.
Thank you all for your help, in advanced. I much appreciate it.
EDIT:
I have tested each battery with a volt meter and each one reads about 4.1-4.2 volts, after a charge. The one thing I noticed, when I tested each individual motor, was that although the average was around 3.7 volts, the voltage fluctuated to around 1.8 and just kept changing, like it was getting less power than what it needed to run at full power.
When I ran it, I could hear each motor changing pitch as it spun. Indicating to me, atleast, that it was not receiving enough power and changed pitch due to that.
I don't know much but it could be the motherboard of the quad, or the batteries are severely damaged and just don't like me
OR It could be the new motor that I just added to it. The new motor was meant for this model but it's possible I have a faulty motor.
