I have a tp4056 li battery charger and I ordered a 440 mah lipo battery. Is it OK to chare battery with this or will be the current too much for battery? Do I need to modify module?
I searched some and find datasheet and I think I should charge it with at most 440 mah and I must change the charging current by changing the resistor at tp4056 module. If I am wrong correct me pls.The module will be fine if it‘s charge current is set to 1A or less. More than 1A is “OK” but will tend to reduce battery life.
The resistor on pin 3 (PROG) determines charge current. Most modules use a 1.2KΩ resistor which makes gives you 1A charge current. If you replace it with a 3KΩ resistor you’ll get 400mA charge current.I searched some and find datasheet and I think I should charge it with at most 440 mah and I must change the charging current by changing the resistor at tp4056 module.

Okay, I replaced it with 4.4k resistor (it was nearest I could find). I assume it should give between 250 to 300 mah but resistor was not at exact point, is it a problem or OK?The resistor on pin 3 (PROG) determines charge current.

It’s fine as long as the reduced charge rate works for you.Okay, I replaced it with 4.4k resistor (it was nearest I could find). I assume it should give between 250 to 300 mah but resistor was not at exact point, is it a problem or OK?
