Description

I couldn't find any compact battery chargers for the TP4056 board, and some often required to have a battery holder, this model only requires wires with a stripped end for the contact point with the battery.

 

Assembly

 

Remove all supports, including the ones inside the small LED hole

Solder wires to the B- B+ contact points

Route the B- to the negative side, you can use blue tack to secure the cable to prevent it from coming back.

Route the B+ wire under the TP4056 and out through the hole

 

When securing the TP4056 board, push the usb c port into the hole, and once the end of the board aligns with the walls, push the board down, this makes it tight so that it doesn't fall (it can be removed by pushing it up like using a flat head screwdriver)

 

IMPORTANT

  • Make sure you don't cut the cable TOO short, they should ideally be hugging the outside wall nearly (to prevent the battery from pushing the cables down), and strip the cables to where appropriate.

Then at last the back cover clicks in with pressure.
