RE: MRC Super Brain 989
I have had mine since late September. I don't have any Lipo's but I have charged all the rest including lead acid and gell cells. It worked great on all of them. It can charge up to 25 cells so you could charge up to 4 six cell packs in series (24 batteries) at once to keep your EMaxx or Supervee charged up. It is also good for battery capacity's up to 19,999 mah so it should be good for some time yet. I have only had Dynamite chargers before so maybe I'm too easily impressed. I like it though.[8D]
