I''m making a portable Bluetooth speaker and need some help with how to charge the battery pack. I have made a 3 cell Li-ion pack with a BMS to get a 12V battery for the speaker. My thought was to charge the pack over USB with the help of a 5-12 Volt step-up converter. ... so neither charging nor discharging is possible. Share. Cite.
In this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery. For example, a battery capacity of 500 Ah that is theoretically discharged to its cut-off voltage in 20 hours will have a discharge rate of 500 Ah/20 h = 25 A. Furthermore, if the battery is a 12V ...
Discharge time is basically the Ah or mAh rating divided by the current. So for a 2200mAh battery with a load that draws 300mA you have: $frac{2.2}{0.3} = 7.3 hours$ * The charge time depends on the battery chemistry and the charge current. For NiMh, for example, this would typically be 10% of the Ah rating for 10 hours.
Charging/Discharging: Your new battery pack arrives between 30-60% SOC depending on how it is shipped. Charge your pack fully before first use. ... and may not be used in any other application.

This means the battery pack, excluding the converter, has 93.9% cycle efficiency for the rated power operation and it is within the range given in other studies [20]. It is observed that SOC value considerably varies while the battery is neither charging nor discharging. This is due to the inaccuracies in measurement and SOC calculation method (1).
