Nichrome wire

Is dangerous to use lipo or li-ion battery for nichrome wire heating?

So long as the current for the wire is within the capabilities of the battery and you are monitoring to avoid any over-discharge it's fine. I've been using old Lipos to run small hot wire foam cutters for years.

But you can make it dangerous if you try...what exactly is it that you want to do?

If you are experimenting then use polyfuses to limit the current to the C rating and use a low voltage cutoff to avoid over discharging the battery. Mistreated lipo or li-ion cells have a tendency to catch fire.

Is ok that I use only tp4056 module for li-ion battery?

Confused! What does that have to do with Nichrome wire?

TP4056 is a charger module for Li-ion/Lipo batteries if that is what you're asking.
