What you need to know about battery charge current
Before starting to charge, first detect the battery voltage; if the battery voltage is lower than the threshold voltage (about 2.5V), then the battery is charged with a small current of C/10 to make the battery voltage rise slowly; when the battery voltage reaches the threshold voltage. At this stage, it enters constant current charging.

How does voltage and current affect speed and torque of a motor?
You''re looking at it slightly wrong : voltage affects speed, but it''s closer to say that torque affects current than vice-versa. So run the motor unloaded : at 12V it''ll run at about 2/3 the speed at 18V, that being the speed at which it generates enough back EMF to cancel most of the driving voltage. (Datasheet says 15200 vs 24000 at 18V).
