Help please! Where do I solder the output? The battery goes on bat+ bat-, but then what? Where's the output pins? I'm powering an old radio. Thanks

There is no out.
This model is battery charge only.

This type has out: Has IC to control battery charge and discharge.

What voltage does your old radio need?

5

The main chip CXA1019P/S can work between 2 volts and 8.5 volts. My battery is a 3.7 v 1500mah. Its a sony icf 18 radio.

Yes, if your radio works with +- 3.4V, but it is not recommended as there is no battery protection.

Are you connecting directly to the main chip?

Trying to do exactly this:

But bought the tp4056 with no output. So my question is how do i correctly solder what in where. :sweat_smile:

It uses two 1.5V D batteries (3V).
Is it safe to connect a fully charged Li-ion battery (4.2V)?
Might damage the radio!

You can add this to your TP4056 to protect battery:

Sorry I don't understand spanish.

TP4056 with protection.

Nobody else has seen your lovely battery so nobody knows if it's "protected".

Fast-blow fuses aren't fancy, but they are effective.
