3S 10A 12.6V 18650 Li-ion Battery Protection Board Charging and Discharging Protection Board Same Port Without Equalization

High-concerned chemical : none Type : Module Brand Name : diymore Origin : Mainland China Condition : New

Features: 1. Built-in multiple protection mechanisms to ensure the safe and stable operation of the battery 2. Maximum support for 10A charge and discharge, to meet the needs of high-power equipment 3. Prevent over-charging and discharging of the battery to avoid battery performance degradation. 4. Compact size, suitable for a variety of portable devices and mobile power supply 5. Adopting high quality components to ensure long-term stable work, trustworthy Parameter: Charging voltage: 12.6V-13V Maximum working current: 10A Overcurrent protection: 25A Static current: less than 6uA Internal resistance: less than 60mΩ Overcharge voltage range: 4.25-4.35V±0.05V Over discharge voltage range: 2.7-3.0V±0.05V Operating temperature: -40+50℃ Storage condition: -40+80℃ Effective life: more than 30,000 hours Short circuit protection: protectable, delayed self-recovery Charging use: Firstly wiring in strict accordance with the wiring diagram. If the voltage of the rechargeable batteries is not the same, the battery with high voltage may be fully charged first, due to “overcharge protection”, the charging protection board will be forced to stop charging, resulting in the battery with low voltage is not fully charged before the charging is stopped. Also, don't use the good battery and the bad battery together, the bad battery capacity is reduced, it is easy to be fully charged, resulting in the voltage rises faster than the good battery, arriving at the value of the overcharge protection voltage in advance, resulting in the good battery being stopped charging before it is fully charged (2 good batteries + 1 bad battery = 3 bad batteries). That is to say, a perfect charging requires three conditions: charging voltage 12.6V-13V; same battery type; same battery voltage; same battery quality. When fully charged, the protection board automatically disconnects the battery from the power supply and stops charging. Discharge use: almost the same as charging, the battery pack should meet the external power supply: the same battery model; the same battery voltage; the same battery quality. Discharge use: If the batteries are not the same, the battery whose power is exhausted in advance will first trigger the “over-discharge protection” function of the protection board, cut off the line in advance and stop discharging, resulting in other batteries not being able to fully discharge.Package list: lithium battery protection board * 1 Package include: lithium battery protection board * 1
