The intent of this post is to be informative, rather than come of like a jerk. Not to say I'm not woefully aware I am capable of the latter...
The issue of not getting units for power (kW) vs energy (kWh) correct has already been covered on the forums many a time. It's an easy mistake to make (or at least typo).
My topic here is regarding electrical potential (aka "voltage") and it's unit of "volts", and the flow of electrical charge (aka "current" or "amperage") and it's unit the "ampere" ("amp" for short).
One of the better analogies (remembering that none are perfect) is that of water. Voltage is analogous to pressure (PSI) which is a measurement of potential. Current is analogous to gallons-per-minute, which is a measure measurement of flow
It seems many posts on the forum use these terms at least awkwardly, and often incorrectly.
For example, "How many amps are in the pack?". As amps are a measurement of flow, that's like asking "How many gallons per minute are in the faucet?" The much better question is "What is the peak current the pack can produce?" which is akin to "How much flow can that faucet provide?"
Similar, "Raising the volts will charge faster." is, awkward, "Increasing the voltage" makes you sound smooth like butter.
Finally, when it comes to current, it is drawn, not pushed. So a motor can "draw" 800 amps. The pack doesn't "push" it.... but it must be capable of providing it.
OK, where are the steps off this soapbox?...
