I am using NCR18650 batteries with the tp4056 charging module.
When I connect the charger at 2.8 V (fully discharged), the tp4056 IC is getting hot at a 1 A charge current. Is it OK to reduce this charge current by changing the charge current selecting resistor? So the tp4056 IC heat would be reduced, wouldn't it?
For my application I don't need a quick charge. With a low current, charging time will be increased, but it does not matter for my application.
Will reducing the charge current affect the battery's lifetime? Or will it damage the battery?
I am trying to reduce the heat of the tp4056 IC by reducing the charging current, maybe from 1 A to 500 mA or less. The 18650 battery never heats for a 1 A charge current.
