Description
The project consists of two files: bv-t5e 1 and bv-t5e 2. Both must be printed.
Assembly instructions:
Insert a TP4056 module with BMS (micro USB version) into the bv-t5e 1 part.
Also install battery contacts in bv-t5e 1 (I used gold pins for this).
Check if the charger works.
Drill a hole in bv-t5e 2 so the LEDs on the TP4056 module are visible (different module versions have LEDs in different locations).
Once everything fits, glue both parts together evenly.
Everything is shown in the photos for reference.
