Panasonic NV-GS90 camcorder battery

Beside printed parts you will need:

• soldering iron
• electrical or kapton tape
• two 13400 li-ion cells (from disposable vapes)
• LX-LISC-V2 usb-c 2s li-ion charging board
• super glue

Please don't buy your cells. Just pick them up from curbside near local school. 

Case - print standing on wall with usb hole. If you confident with your bridging game you can do it without support.

Spacer - print standing up, fork side up.  Brim strongly advised, tree supports under overhangs.

Lid - flat side to bed, easy peasy

15% triangle infill, 2 walls, PET-g

Assembly:

1. Take 2, single stranded, wires and strip about 4cm of one end. Fish them through holes in the case and back. Use needle nose pliers and twist wires tightly. 
   
2. Solder twisted wires. Use a LOT of flux always.  
   
3. Bend the wires toward front face and tape it with electrical tape or better - kapton tape
   
4. Solder 13400 cells in series. Use longer wire, we need it for balancing cells.
   
    
5. Place PCB inside spacer. Place it on li-ion cells. Use electrical tape for easier work. Solder balancing wire FIRST. Then solder wires to B+ and B- on PCB. Finaly solder wires to positive and negative of battery.
   
6. Remove tape and put battery inside case.
   
7. Solder remaining wires to B+ and B- pads on PCB. Thats good (and last) moment to test if everything works ok.
   
8. Glue lid on and its done :)
