Thanks for the responses guys. I will check around to see what type of breakers I have, I have a feeling that they are the temp style and are likely a little corroded. I dont think that it is batteries because they are fairly new and the problem only occurs when Im on high and it goes completely off, not just slows. Before, after a minute or so of running at a lower speed I can increase back up to fairly fast and had no signs of a lack of power. But now its not functioning normally at all. BCB will there be a breaker for each battery? and is there is any way you could post a picture of the temp style breaker so I know what Im looking as Im a little ignorant on electronics. Thanks again for all responses.
