I used a similar Module with an LCD for my DIY powerbank. It was very reliable, but the old batteries croaked soon

What do you think, Does it worth the Money?

Very nice board i have used one in my DIY slim powerbank with two Lipo batteries i took out from two old android tablets.

The title should indicate the real cost of the module, like "0.68$". More interesting title is that.

I wonder if I can use this to make a UPS Power supply for a Raspberry Pi zero.

Hello my friend. Is there a 2 in 1 module that charge lithium 3, 7v battery but also can reduce or boost voltage from the battery. I am changing all disposable battery gadgets. Some have 2xAA =3v. Some have 3xAAA= 4, 5v and some have 9v battery.
