I would also like to see a parts list for this circuit.

Lithium ion battery charging and discharging circuit.

Also i have tried to locate without success the schematic symbols labeled x1 and b 1 b 2 and j1 j2 and j3. A li ion battery reaches full charge when the current drops to a set level. Can you help me design a circuit to charge 25 li on cell battery 3 7v 800ma each at the same time. If the values go beyond critical value the module will automatically disconnect the circuit and protect your battery.

As we know a lithium battery should not be overcharged or over discharged hence this module will monitor the voltage level of the battery during charging and discharging. In a li ion battery lithium ions move from one intercalation compound to another while electrons flow around the circuit to power the load. Charging many li ion battery together. In very basic terms the charge and discharge of a lithium ion battery is relatively easy to explain.

Also let me know how many amps of the 12v battery would be drawn with this setup per hour thanks in advance. Avoid completely discharging lithium ion batteries. Charging the battery forces the ions to move back across the electrolyte and embed themselves in the negative electrode ready for the next discharge cycle figure 1. A lithium ion battery or li ion battery abbreviated as lib is a type of rechargeable battery lithium ion batteries are commonly used for portable electronics and electric vehicles and are growing in popularity for military and aerospace applications.
