The discharge current is the amount of current drawn from the battery during use, measured in amperes (A). Li-ion cells can handle different discharge rates, but drawing a high current for extended periods can generate heat and reduce the battery’s lifespan.
When the lithium-ion battery discharges, its working voltage always changes constantly with the continuation of time. The working voltage of the battery is used as the ordinate, discharge time, or capacity, or state of charge (SOC), or discharge depth (DOD) as the abscissa, and the curve drawn is called the discharge curve.
Lithium-ion batteries are particularly sensitive to overcharging and discharging, so avoid charging more than 100% or discharging less than 20%. Charging when the battery power drops to about 30% is recommended. Keeping battery power between 40-80% can slow down the battery’s cycle age. 2. Control charging time
That will cause that battery to discharge a tiny bit faster, and at some point, that battery's internal voltage will drop to where the other battery will start to carry more of the load. After that point, the cells will self balance. With LFP cells, the voltage change is very slow, so it can take a while to get there.
Li-ion batteries, for example, have a limited number of discharge cycles before their performance begins to degrade. By regularly discharging your battery to its full capacity, you may be shortening its overall lifespan. Instead, it’s recommended that you aim to discharge your battery to around 50% before recharging it.
The lithium-ion battery discharge test mode mainly includes constant current discharge, constant resistance discharge, constant power discharge, etc.
