EV design – battery calculation – x-engineer.org
The battery cells manufactured by A123-Systems have very high maximum continuous discharge current and maximum pulse (peak) discharge current. As for energy and capacity, the pouch type cells have higher peak (continuous) current and power than cylindrical cells.
Maximum AA battery current draw? - Page 1 - EEVblog
· The internal resistance of alkaline and primary lithium batteries is too high for that kind of discharge rate. Power dissipated in the cell will be current^2 x internal resistance, and this heats up the cells. There will also be significant voltage sag of I x R. The capacity (mAH) is also greatly diminished at high discharge rates.
Battery Ratings | Batteries And Power Systems
· A battery with a capacity of 1 amp-hour should be able to continuously supply current of 1 amp to a load for exactly 1 hour, or 2 amps for 1/2 hour, or 1/3 amp for 3 hours, etc., before becoming completely discharged. In an ideal battery, this relationship between continuous current and discharge time is stable and absolute, but real batteries

Batteries and Inverters - First National Battery
· Batteries and Inverters – Choosing the Right System Now a typical deep cycle battery has a capacity of 105 Ah. Remember that one should not aim to discharge the battery more than 50%. Thus for the purposes of design, there is only 52Ah available. So that battery would supply 20.1 amps for 52 / 20.1 = 2.6 hrs. Thus a single 105Ah battery would be sufficient to drive all those devices long
