The discharge curve of a 3.7V lithium-ion battery shows how the battery voltage changes as it discharges. At full charge, the voltage is around 4.2V, and as the battery discharges, the voltage gradually decreases.
The highest diagram they shown details a max discharge of 1C, they also mention in the handling guidelines to not let the battery voltage drop below 2.7V so you may need to do some voltage monitoring to be safe. Annoyingly thats the only mention I can find of discharging, so from that you could possibly assume the max discharge is 1C.
The 3.7V rating signifies its average voltage output during discharge, ensuring consistent power delivery. With capacities ranging from around 1500mAh to over 3000mAh, these batteries cater to diverse energy requirements. 18650 battery voltage is one of the important parameters of an 18650 lithium battery.
The maximum safe charging voltage for a 3.7V lithium-ion battery is 4.2V. Charging beyond this voltage can cause the battery to overheat, leading to reduced battery life and even safety hazards. How can I interpret a voltage chart for a 3.7V lithium-ion battery?
Buy batteries with spec sheets from reputable vendors. Even when you do that you may sometimes get fake batteries. There's probably very little capacity left below 3.2V so I'd be inclined to take that as a max discharge, though 3V should be safe. It'll last longer if you don't use either extreme of its capacity range.
