I have a Dynamite 7.4 volt 1900 mah battery pack for my mini-t. I don't know what to set our charger at though. It is a Superbrain 977. It says check the batteries instructions for charging but we bought it off Ebay so I don't have any instruction. I need to know what to set the amps and mv at. Also it says that it should say lipo on the screen but it doesn't. Thanks.
