no, nothing is binding. When a full charge is given, (at this point just 10 min.) the xrb works perfect, but then shuts down after about 2-3 min. Like i had said before, everything was working perfectly (esc was cutting off after about a 10-15 min runtime, but now it cuts it after about 2 min. Then it takes about 10 or so min to charge the battery back to full. Readings are 8.4V. 4.2 per cell. When the problem started it went from working perfect to doing this in a matter of a second. one second it was fine, the next it was broke. It wasn't an intermident problem.
