10PCS 18650 battery protection circuit board, has been welded nickel belt. 18650 two MOS Protection Board PCB + Free shipping Main technical features: 1, overcharge protection Overcharge protection means reaches a voltage (hereinafter referred to overcharge detection voltage) is prohibited by the charger to continue charging. That is, the control overcharge MOS tube into the off state to stop charging. 2, over-discharge protection Over-discharge protection in the battery voltage becomes low, stop the load discharge. The control over the discharge of the MOS tube into the OFF state, the discharge is prohibited. This process coincided with the overcharge detection operation when the opposite. 3, over-current, short circuit protection Overcurrent protection function is to stop the discharge of the load, the purpose of this function is to protect the battery and the MOS transistor when the current consumption to ensure the safety of the battery in working condition. After overcurrent detection, battery and load out will return to normal, can be charged or discharged. The main function: 1. overcharge protection 2. Over-discharge protection 3. overcurrent protection 4. Short-circuit protection Multiple protection safety Rest assured. Durable battery for your escort! & Technical Parameters: No. Test Item Standard 1 voltage charging voltage DC: 5V CC / CV Single balanced voltage 2 Current single equalizing currents Single battery consumption (self-consumption) ≤6uA Maximum continuous discharge current 3A 3 Overcharge Protection Over charge detection voltage 4.275 V ± 0.025V Overcharge detection delay time 150-500 ms Overcharge recovery voltage 4.075V ± 0.025V 4 over-discharge protection over-discharge detection voltage 2.50V ± 0.1V Over discharge detection delay time 50-150ms Over discharge recovery voltage 2.9V ± 0.10V 5 overcurrent protection overcurrent detection voltage 150 ± 30mv Over current detection current 4.5 ± 0.5A Overcurrent detection delay time 5ms-15ms Restore state auto-recovery 6 external short circuit protection detection state Detection delay time ≤50us Restore state auto-recovery 7 Resistance Protection circuitry (MOSPET) ≤40mΩ 8 Temperature Operating temperature range -40 ~ + 50°C Storage temperature range -40 ~ + 90 °C & Welding Point Description: · B + connected battery cathode; · B- take battery; · P + connection charge / discharge upright pole (end charging / discharging terminal common); · P- take charge / discharge end of the negative electrode (the charging terminal / discharge end share).
