1) The battery has a maximum power it can provide. For example, if this power is P = 100 W, then since P = RI^2 the current will be I = (P/R)^0.5 = 31.6 amps and the voltage V = RI = 3.16 V. 2) The battery has a maximum current it can provide. For example, if this current is I = 5 A, then V = RI = 0.5 V.

maximum capacity. A 1C rate means that the discharge current will discharge the entire battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. A 5C rate for this battery would be 500 Amps, and a C/2 rate would be 50 Amps. Similarly, an E-rate describes the discharge power.

$begingroup$ The charge voltage depends on the battery chemistry. Some lithium ion batteries are charged to 4.2v, some to 3.6v, etc. And the battery voltage will vary with the current charge state - less charge means less cell voltage, but the relationship is not linear (quick drop from completely full, flatter plateau for a while, quick drop again when getting low).
