Banana battery - protected or unprotected?

[MadMax]

I was searching for a UPS for the Banana classic and then saw you just can connect a battery to it.

What i can't find information about if it needs to be unprotected or if i can use my protected Keeppower 18650 Li-Ionen's that i already have for my flashlight anyway.

 

And is there anything special i need to do in Armbian? Just connect the battery and it works?

Hard to find information :-(

Exactly. Protected is recommended, but it will also work without.
