# Lion Collar Payload (primary battery)

## Electronics

1. primary testing
2. add GPS antenna 
3. GPS antenna testing
4. GPS antenna tuning (1592 MHz in air)
5. remove 2 components from the charger (positions D3 + U13)
6. remove all components from the top part of the board (above the EMI shield)
7. add zero-ohm resistor 
8. add EMI shield (temporarily attached in one corner)
9. add tag extension 21,4 mm + tag (do not solder right-side battery/2,5V pins on the tag extensions) 
10. tape underneath the tag to protect holes for programming from the resin
11. enlarge holes on the charger (2 mm drill)
12. battery 5-pack assembly (5x Saft-14250; 3mm x 0.1mm welding strap)
13. apply hot glue all around the EMI shield (to prevent the resin flowing underneath it)
