Modification 2 Dry battery toy remote control Mouse single-chip machine modified lithium battery 3V-4.2V lowered 3V charging discharge

Features:

Lithium battery drops 3V and other voltages.

Integrity with discharge, protection, charging management

Small size and small space.

Small static current, suitable for a long time.

Perfect protection functions, specific short -circuit overheating, overcurrent, over pressure protection.

parameter.

1. Battery voltage: 5V.

2. Output voltage: 3V.

3. Output current: 1A (MAX) (long -term work recommendations below 800mA).

4. Charging current: 300 (MAX), you can customize.

5. The battery over placing the protection voltage: about 3V; full voltage: 4.2V about 4.2V

6. Charging indicator: The charging is often bright, full of extinguishing;

7. Static current: about 60UA

8. Size: 18*9*2.3mm.

9. Weight: about 0.5g, add a total of about 1g in a total of 1g.

Note: The connection line between the battery and the module is as short as possible, and the copper wire is used.

Tip: If the battery capacity is too small, it will cause a state of full and unsuccessful, just like the phenomenon of connecting water with a small cup in the water faucet; the R2 resistance value can be replaced, the R2 resistance value is 10K charging about 100mA, R2 R2, R2The resistance value is about 2K charging about 500mA.
