I have built a quad and since it wasn't flying, I began testing each ESC and was calibrating the throttle range, and all that stuff etc.
ESC:
Power HD 20A Brushless ESC
Motor:
dt700 from HK
LiPo:
3S 3000mAh (Zippy Flightmax)
At first the voltage read some
11.6V. I calibrated the ESC and casually put that single motor on full throttle
without prop[/b]. After about 70 seconds, I stopped and checked the voltage. It read
8.19V! I was SHOCKDED! What's wrong with my LiPo? Please help.
(Or would you say this is normal?
)
Then, I tried charging it. I only have this cheapest charger on earth:
http://www.hobbyking.com/hobbyking/store/__7637__Turnigy_balancer_Charger_2S_3S.htmlI gave a good 12V DC supply and connected my LiPo using the JST-XH connector given. It charged well at first and then the voltage finally reached some
10.5V. So I tested at
full throttle once again (without prop). This time the voltage came down to
8.4V. But when I try to charge it once again, it doesn't charge! WHY! I've checked for all lose contacts, etc, opened the charger and seen, but nothing is damaged apparently. Please help.
