I had a Duratrax Onyx charger before but i have recently upgraded to the venom charger. I just got this charger a few days ago and haven't fully figured it out yet. I haven't flown in months but i really want to get out tomorrow and fly since the heat has broken for a few days. I have a JR 4-cell 2700mah Nimh battery that i want to charge. Can somebody give me the exact figures that i need to input to charge this battery. (on a seperate note i never liked the onyx 230 bc it always said that it put the entire 2700mah in the battery pack even when i new that it still had halt-(3/4) charge left, i guess it wouldn't detect the peak charge like i'm hoping this charger will) Thank you to anyone that can help me out!
