What do you recommend to me to measure this kind of battery capacity in a reasonable time like 3-4 hours. A 1700 mAh battery would be discharged in 3 hours by 1700/3 =~ 570 mA and in 4 hours by 1700/4 ~= 425 mA. So using about 500 mA and seeing how long it takes will give a measure of battery capacity. The current of the3 load in the circuit ...

Lithium-ion batteries have become the primary electrical energy storage device in commercial and industrial applications due to their high energy/power density, high reliability, and long service life. It is essential to estimate the state of health (SOH) of batteries to ensure safety, optimize better energy efficiency and enhance the battery life-cycle management.
It''s a crucial variable for determining how much energy is still there in the battery. State of Health (SOH): SOH is a measurement that depicts a battery''s overall health and how long it has left to live in comparison to a brand-new battery. It considers elements including the number of cycles, capacity fading, and changes in internal resistance.
Battery SOE refers to the ratio between the battery''s remaining available energy and its maximum available energy. It is typically represented as a percentage between 100% (fully charged) and 0% (fully discharged). Tracking SOE allows the BMS to determine how much usable energy is left in the battery at any given time. This is one of the most critical …
Direct methods involve measuring the battery''s actual electrical charge. These methods are the most accurate but can be difficult to implement.
