Orion's lipo's are the best when it comes to safety and they sacrificed a little performance to ensure the best quality on the market. A battery is a battery yes but there will always be little companies cutting corners to give cheaper prices resulting in not so good equipment. I will say that a well used 2year old 4800 hooked up to a trak power had the balancing lights on for maybe 10seconds where a brand new trak power had to be balanced every time.
