Human: Fatshark battery case allows you to build a high capacity DIY battery for your beloved FPV goggles. I built this one because I couldn't find any other design that would fit the 2S Battery Voltage indicator sold by Banggood, 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 connection schematics. To close the case, use hot glue or a large enough heat-shrink tube that fits the case inside it. **Important:** You need to file the positive and negative terminals of the batteries slightly to allow solder to stick in place. Use sandpaper or a metal file for this purpose. When you proceed to solder, do not heat the batteries for more than 3 seconds. Keep an eye on their temperature at all times. They can explode if overheated. Do it quickly and repeat as necessary, allowing them to cool down completely each time.
