SJCam SJ4000 battery charger

thingiverse

This is a housing for an SJCam (SJ4000) battery and TP4056 charging board. It features two small slots to fit small pieces of nickel strapping as battery connectors. The second photo illustrates the basic idea: 1. Print the two pieces, printing the lid in translucent PLA if available 2. Acquire a TP4056 lithium Ion charging module (I purchased this one: https://www.aliexpress.com/item/5-pcs-Micro-USB-5V-1A-18650-TP4056-Lithium-Battery-Charger-Module-Charging-Board-With-Protection/32774386435.html) 3. Cut two small pieces of nickel strapping (I obtained some from an old laptop battery) and bend them to fit into the slots. Bend the strips so that the fold is at the top 4. Solder the nickel strips to the battery outputs of the TP4056 module 5. Seal the nickel strips with hot glue on the module side to secure them in place 6. Place the lid over the module and it's complete It's a straightforward design - and it functions perfectly. Oh, and I don't charge the SJ Cam via its USB cable because its socket is damaged.
