The batteries used in power packs typically discharge (provide power output) at about 3.6V or 3.7V and recharge at 4.2V. (Lithium-ion cells, used for all the packs I tested, charge best at about that rate.) When you see that a battery pack has 10,000 mAh, that’s 10,000 mAh available at 3.6V or 3.7V.
However, all of this takes time and hence please use this as a first approximation. The battery pack mass is roughly 1.6x the cell mass, based on benchmarking data from >160 packs. However, there are a number of estimation options and always the fallback will be to list and weigh all of the components.
Most manufacturers list how many charges a battery can give a certain smartphone. In our tests, 10,000mAh of battery pack capacity translated to roughly 5,800mAh of device charge. 20,000mAh chargers delivered around 11,250mAh to a device, and 25,000mAh banks translated to about 16,200mAh of charge.
(Recommended) Charge Current – The ideal current at which the battery is initially charged (to roughly 70 percent SOC) under constant charging scheme before transitioning into constant voltage charging. (Maximum) Internal Resistance – The resistance within the battery, generally different for charging and discharging.

High power packs need to operate over a narrower state of charge window if the power delivery is to be consistent. A long range BEV will have a very ''wide'' usable SoC of around 90 to 95%. A HEV that discharges and charges the pack in an aggressive way would need a ''narrow'' usable SoC of around 30%.
