I think it makes a really loud chirping sound, or it cuts it off to 50% power. Not sure. Oh and also Hobbyking.com has lots of good lipos and chargers as well.
i HIGHLY recommend staying away from anything chinese, especially during or shortly after a holiday.
hobby partz is about the same cost and your keeping the money in your country.
i orderd a cheep motor from hobby king 3 weeks ago just because it was $10, still no motor, i order from hobby partz, i get it in the retail box within a box in 4 days.
