im charging several batteries. 2 2500mah 9.6 rx packs, a 1700mah 8.4v 7cell pack and a 200mah 6 cell 7.2v pack. all are being charged according to the specs in the owners manual. the charger says done when the rx packs get to around 200mah. the other 2 packs get around 150mah and the charger says completed and beeps. all packs were completely dead. the 6 and 7 cell packs charge perfectly on my dynamite charger. i cant charge the rx packs cause they are 8 cell.
