Description:The main IC adopts the original "Ricoh" import components. Have overcharge, discharge, over current, short circuit protected function, use as in a variety of capacity of 3.7 V lithium batteries. Adopt NSK-protected IC, VISHAY, AOS, IR high-quality MOSFET, FR - 4 planks, low-temperature coefficient, and excellent design, fine workmanship, complete testing. Small size, suitable for many occasions with high integration, low-cost requirements, ensure the battery pack absolutely safe and reliable

Feature:- Built-in high precision voltage detection circuit.- Connect to the charger terminals using a high-pressure device.- Built-in three overcurrent detection circuits (1 over current, 2 over current, load short circuit)- Through the MOS tube,it can control the battery charging and discharge;- Low standby current consumption

Properties of the lithium battery protection boardModel: HH-P3-10.8Charging voltage range: 4.25-4.35V 0.05VSize: 48 * 15 * 1.0 mmDischarge voltage range: 2.5-3.0V 0.05VMaximum working current: 3AWorking temperature: - 40 -50 CMaximum instantaneous current: 4-6AStorage conditions: - 40 -80 CStatic electricity: less than 6 uAUseful lifetime: more than 50000 hoursResistance: less than 45 mShort circuit protection: can protect, need charging

Function:Connect the lithium battery with a protection board according to the wiring diagram, when the battery voltage is between the charging pressure and discharge voltage, and the P +, P - charging after 1 second, the output voltage P + and P - is the same as the battery voltage.
