Didn't your setup come with a charger? That would be the one to use if it did.

If they are regular lithium ion 3.7v batteries your charger will charge to 4.2v.
The 8.4v one must be 2 lithium ion batteries in series. You will need a hobby charger for that one and then the proper connector for it.

I charge my 3100mAh batteries anywhere between 400mA to 1 amp depending on the charger I'm using.

This is just a vague answer without really seeing the batteries or the connector.
