BMS 5s String (18.5V 15A ) Lithium Battery Protection Module

Description

BMS.5S.15A 5S 15A Li-ion Lithium Battery 18650 Charger PCB BMS 18.5V Cell Protection Board Integrated Circuits Specification: Size: 90 * 16 * 3.0mm Continuous discharge current: 15A(max) Instantaneous discharge current: 25A Charge voltage: 21V Charging current: 15A(max) Overcharge Protect: Over-charge detect: 4.28±0.05V & Protect delay: 0.5s Over-charge release: 4.28±0.05V Over-discharge Protect: Over-discharge detect: 2.55±0.08V & Over-discharge detect delay: 0.1s Release voltage: 2.9±0.1V Short-circuit Protect: Protect condition: Cut load & Detect delay: 250uS Release condition: Cut load Over-current Protect: Detect voltage: 150mV & Detect delay: 9mS Current detect: 30±3A Release condition: Cut load Inner Resistance: ≤20mΩ Self-consumption: Working current: ≤30uA Sleep current: (when over-charge)≤10uA Working Temperature Range: -30-+80℃ 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.
