BMS 4S (16.8V - 8A)Lithium Battery Protection Module

Description

4S 8A 14.8V 16.8V 18650 Lithium Battery Protection Board 4 Cells Li-ion Lipo Polymer Charger Protection BMS/PCM/PCB Module Specification:Size: 72 * 17 * 3.0mmOvercharge voltage range: 4.25-4.35v ± 0Over-discharge voltage range: 2.3-3.0v ± 0.05vUpper limit working current: 6~8AUpper limit instantaneous current: 12AQuiescent current: less than 30uAInternal resistance: less than 100mΩCharging voltage: 16.8V-17VOperating temperature: -40 to +50 °Storage conditions: -40 to +80 °Effective life: more than 50,000 hoursShort circuit protection: can be protected, need to restore the chargeProtection board components: Components for the S-8254AA protection chip and AO4407 * 4.Main function:Overcharge protection, over-discharge protection function, short circuit protection function, over current protection function, balance. Important Cautions:Strictly according to the diagram wiring - do not make short circuit.After the wire is connected, it needs to charge the batteries first, then have output.When the battery is connected in series with 5 groups, please ensure that the voltage of each battery is the same. If not the same, please fill in each set of batteries and then use them.Do not mix the good battery and the bad battery.It will be better if the capacity of the battery's internal resistance is closer.
