| + | [title] Building a Charger Tray |
|---|---|
| + | [* black] Attached you can find a STL file (under Media) to 3D-PRINT a charging tray for the new pin layout (remember blocking some pins so the Rollei Charger N cannot fry your new battery). The 3D Model can also be downloaded from here: https://www.thingiverse.com/thing:2156779 |
| + | [* black] Print the 3D Model (or get it printed online). |
| + | [* black] Get a connector socket (for the charger I used I got one of these: https://bit.ly/2NwmhUo ) with 12.6mm diameter (you can use others but the 3D model might not fit then). |
| + | [* black] Solder wires to two pins (check the diameter of the pins so they fit the battery!) Make sure they're tick enough to have electrical contact. I used two small nails I shortened. Glue the pins into the two holes so they stick out roughly 5-6mm. Validate that the battery fits and connects (use a meter!) |
| + | [* black] Solder the other ends of the cables to the socket and glue the socket into the hole. Fill the bottom side of the tray with hot glue to fix everything. |
| + | [* black] A charger can be ordered from eBay: search for 11V Charger 1A Smart to 9.6V LiFe LiFePO4 |
