The protection board size and device description;

Main functions and features: over charge protection, over-discharge protection, short circuit protection, overcurrent protection.

The protection board uses Ricoh Japan rechargeable lithium iron phosphate battery protection IC;

1) Built-in high-precision voltage detection circuit;

2) terminal of the charger using high pressure devices;

3) Built-in three overcurrent detection circuit (overcurrent 1, overcurrent 2, load short circuit);

4) through the MOS transistor can control the battery charging and discharging;

5) Low standby current consumption.

Function and description:
1, the lithium battery with protection board according to the wiring diagram connection, when the battery voltage is overcharge and over-discharge voltage between the voltage, and P +, P- charging a second, P + and P- output voltage of the battery voltage.
Battery charge function: between P + and P- plus charger to charge the battery, the battery voltage charge to overcharge detection voltage (4.25 ± 0.025V), the protection circuit to cut off the charging path, to achieve overcharge protection.
Battery over-discharge protection: between P + and P- connected load the battery discharge when the battery voltage drops to over-discharge voltage (2.4 ± 0.08V), the protection circuit, shut off the discharge path to achieve the over-discharge protection.
Short circuit protection function: When the P + and P- short circuit protection circuitry rapid action in the 5-50uS, cut off access, short-circuit protection.
Overcurrent protection function: When V- terminal voltage of (0.15 ± 0.02V), the protection circuit will act quickly in 6.7-13.9ms, cut off access, overcurrent protection.
Note: If the correct welding, testing the output No output, use other ways to activate charging about protection board!

Note: This protective plate is precision originals, the factory has been rigorously tested, once the sale is not in front of the welding quality problems found by our responsible, has been found after welding quality problems will not be returned. Use a good test before work!
