The main IC adopt 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 plank, 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 which using high pressure device. - Built-in three over current detection circuit (1 over current, 2 over current ,load short circuit) - Through the MOS tube ,it can control the battery charging and discharging; - Low standby current consumption Properties of the lithium battery protection board Model: HH - P3-10.8 Charging voltage range: 4.25-4.35 v±0.05v Size: 48 * 15 * 1.0 mm Discharge voltage range: 2.5-3.0V±0.05v Maximum working current: 3A Working temperature: - 40 --- +50 ° Maximum instantaneous current: 4-6A Storage conditions: - 40 --- +80 ° Static electricity: less than 6 uA Useful life time: more than 50000 hours Resistance: less than 45 m Ω Short circuit protection: can protect,need charging Function

Connect the lithium battery with 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 seconds,the output voltage P + and P - is the same as the battery voltage.
