Battery 18650 Li-ion Protection Board 4s 4A **LOCAL STOCK**

Battery 18650 Protection Board 4s 4A:

Specifications:

Over Charge Voltage: 4.2 - 4.3V DC
Over Discharge Voltage: 2.3 - 3V DC
Charge Voltage: 12.6 - 13.6V DC
Operating Current: 4-5A
Size: 48 x 15 x 1mm

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

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 1 second, P + and P- output voltage of the battery voltage.

2. the 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.

3. Battery over-discharge protection: in between the P + and P- connected load to the battery discharge
when the battery voltage drops to over-discharge voltage (2.7  0.05V), the protection circuit,
shut off the discharge path to achieve the over-discharge protection.

4. Short circuit protection: When the P + and P- short circuit protection circuit will act quickly in 5-50uS,
cut off access, short-circuit protection.

5. Overcurrent protection function: When the V- terminal voltage of (0.15 ± 0.02V),

the protection circuit will act quickly in 6.7-13.9ms, cut off access, overcurrent protection.
