if its 5.42 volt the batt will not charge anymore. minimum has to be 7 volts.lipo bat dont charge if it comes below 7 v

@Nomad... Lipos have a minimum voltage of ~3.00v per cell... Meaning 6v not 7v is the theoretical minimum.... Please try not to give incorrect info.... If you aren't sure just google it...

3.7V is the average voltage; LiPo can be charged up to 4.20V and discharged down to 3.0V per cell, any lower or higher in voltage and the cell will almost certainly be damaged and will become unstable which can be very dangerous (fire risk).

Great. Still doesn't really help me. Do I have a bad battery and what can I do about it? I contacted the warranty department.

somebody here told me that this could happen at volt 6.9 i dont give a name but it was one off you.

Contacting warranty is correct. Where are you located? If you are in the Baltimore/Washington area, I can loan you a working battery tomorrow until your warranty replacement arrives.

Thanks, Alan but we are in the Niagara Falls, Ny area! I will wait to hear from customer service.

Ok. They'll certainly take care of you, but the shipping time can be frustrating, particularly for a kid wanting to use a new present. Most hobby shops that sell RC planes or cars will have compatible batteries, and it never hurts to have a spare. You'll need a 2S 1300 mah LiPo. Should be less than $15.

You're contacting the right place There is nothing to be uncomfortable about - we are the company that company that makes the robot, so you're doing exactly the correct process. Someone who's in customer support will be replying to your Contact Us message.

In the meantime, did you use the robot before charging the battery?
