Circuit diagram like in figure 1 above is Circuit Diagram Compact 2S LiPo Battery Charger using LM317. According Electroschematics site describe that the compact LiPo battery charger introduced here can be used to charge almost all standard 2S LiPo battery packs. The circuit, designed around generally available low-cost components, is very simple, safe, and economical. The typical target voltage of a 2S LiPo battery is usually 8.4 V (note that target voltage is not the same as the nominal voltage, which is 7.4 V typical), and LiPo batteries require a special type of charging mode that uses the CC/CV method (constant current/constant voltage) with 1-C charge grade (1 A for a 1,000-mAh battery). However, charging at a lower-than-1-C rate is perfectly safe and will not damage any battery type. The design is optimized for batteries of 1,000 mAh or higher, and the input power source can be any linear/switch-mode power supply capable of catering an output current of minimum 1,500 mA at 18 V. Normally, a LiPo battery connected to this circuit will be charged to 95% of its nominal voltage within 60 minutes and charged up to 100% of its target voltage within two hours thereafter.
