LM317 made with lithium ion, lithium polymer charger circuit both current and voltage at 8.2V and 12.6V 4.2V adjustable output that can give you 2 … 3 rechargeable batteries connected in series. Shir input voltage 12v dc circuit
Current settings easier to use because it is gradually 10mA …. 985 from the current setting can be made.
In this state, both power and voltage as the circuit quite well actually instead of LM317 lm350 (3 amps) or LM338 (5 amps), and using their power on the circuit by changing resistor values may be a more powerful charging circuit.
