Since this is a particularly confusing part of measuring batteries, I'm going to discuss it more in detail. Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh).
However, the amount of current we can really draw (the power capability) from a battery is often limited. For example, a coin cell that is rated for 1 Ah can't actually provide 1 Amp of current for an hour, in fact it cant even provide 0.1 Amp without overextending itself.
Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh). A Watt-hour is the voltage (V) that the battery provides multiplied by how much current (Amps) the battery can provide for some amount of time (generally in hours). Voltage * Amps * hours = Wh.
The battery capacity vs discharge is far from linear, and the mAh rating is quoted against a low discharge rate (~0.1*capacity). Secondly your circuit will use as much current as it needs. Trying to limit the current is likely to stop it working. To use less current, redesign the circuit.
So, yes. Batteries have a max current drain (given by design and physical/chemical limitations) and yes the storage rating (being Ah, Wh or Joules) changes depending on battery design and load applied, and yes Wh is a better way to compare batteries because it takes voltage in account.
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.
My battery, which has a 6.5 kWh capacity (LG RESU6.5), seems to have a maximum output of about 2.67 kW. I''m not sure if this limit is set by the battery or by the …

The battery made from Menril trees is amazingly powerfully stupid. Give it redstone signal if you want it to power things. Seriously. Add a lever and flick it and it''ll output to anything touching. …
If you draw current very slowly from the battery, then up to a point you''ll get the maximum energy out of the battery -- but above that point, the battery''s self-discharge current (which I''ve modeled with R2) dominates.

In a lot of battery applications the State of Power (SOP) is a key output from the BMS. This will take into account the State of Charge, State of Health and other parameters such as temperature. How much power can the battery pack …
I hope to get around this by having a large PV (circa 17kw) array to charge a suitably sized battery bank (in the style of attached picture but without the Genset). My …
If you want to limit the amount of power being drawn from the battery, you will have to set this limit slightly lower to compensate for those losses. Power coming from the …
