Fatshark battery case to build a high capacity DIY battery for your beloved FPV goggles. I built this one because I could not find any other design that would fit the 2S Battery Voltage indicator that Banggood is selling, so here it is. Component list: - 2S Battery Voltage Indicator: https://www.banggood.com/2S-3S-4S-5S-Lipo-Battery-Voltage-Display-Indicator-Board-Polymer-Power-Indicator-Panel-p-1095698.html - Balancer cable for 2S: https://www.banggood.com/2_54XH-22AWG-13CM-1S-2S-3S-4S-6S-8S-Balance-Cable-Silicone-Wire-for-Lipo-Batteries-p-1018898.html - 2x 18650B batteries: https://www.banggood.com/2PCS-NCR-18650B-3_7V-3400mAh-Protected-Rechargeable-Lithium-Battery-p-90990.html - Male DC Jack connector 5.5 x 2.1: https://www.banggood.com/DC-Tip-Power-Plug-Jack-Connector-Dual-5_5-x-2_1mm-Male-Right-Angle-Cord-Cable-p-1161332.html I will update the description with the connection schematics. In order to close the case, use hot glue or a big enough heat-shrink tube that fit the case in it. **IMPORTANT:** You will need to file a little bit the positive and negative terminals of the batteries to allow solder to stick in place. You can do that with sand paper or a metal file. When you proceed to solder **DO NOT heat the batteries for more than 3 seconds**, and always keep an eye at their temperature. They can explode if they are overheated. Do it quickly and do it in several times if needed allowing to complete cool down the batteries.
