1S 3.7V 2A 3A 4.5A 6A 7.5A 9A Li-ion Battery Protection Board For 18650 Li-ion Lithium Lo Battery Cell-1S 2A 3.7V 1MOS

Precautions 1. Before installing the protection board, the battery should be matched well (the voltage difference between each battery should not be 0.05V, the internal resistance difference is not more than 5mQ, the tolerance is le than 30mAh), the smaller the battery voltage difference, the better the protection board will work. . 2. The batteries are connected in parallel and then connected in series, and the welding is correct (18650 battery nickel spot welding, other batteries are soldered), do not screw, easy to burn the protection board IC. 3. If it is an old battery change board, please pay attention: Please confirm the battery is normal before buying? 4. When installing, use a to check whether the voltage of each string is the same? The performance fais with a difference of more than 1.0V are: running not far, starting and powering off, charging time is short, basically the battery core problem is more. The fai of the protection board is as follows: the battery cannot be charged, and the battery has a voltage and cannot be discharged. Parameter Long-lasting discharge current: 2A-9A Single-cell consumption of battery (self-consumption): ≤3uA Charging voltage: 3.7V Charging current: 2A-9A Overcharge detection voltage: 3.7±0.05V Overcharge protection delay: I S Overcharge release voltage: 3.7±0.05V Over-discharge detection voltage: 2.0-2.1V Over-discharge detection delay: lO0mS Over discharge release voltage: 2.3±2.1V Package included: 1 x1S 3.7V 2A 3A 4.5A 6A 7.5A 9A Li-ion Battery Protection Board for 18650 Li-ion Lithium Lo Battery Cell
