i use an eagle CDC charger v5.0... you would probably know it as an integey something..
i charge my trinity 1100mah NiMh RX packs at the following settings:
1 amp
peak detect mv: 4mv
discharge: 0.8 amps
this has worked for me fine, i discharge my packs and put about 40 percent charge in them because they have to sit around for 3 weeks between races... i have two packs one i use for races and the other i use for testing.... the race pack gets less use and the best treatment. the practice/testing pack gets a kinda hard life (in comparison to the race pack) and it works equally as good as the better pack
