Product Overview
Brand: MakerFocus
Features:
- Charging Method: Recommended charging current of the battery is 0.4A, the maximum does not exceed 1A. The recommended discharge current is 0.4A, and the maximum does not exceed 1A. This battery protection board is equipped with two mos tubes, overcurrent protection (instantaneous) 3.2A-5A, charging voltage setting recommended 4.2V
- Overcharge Protection: When charging the battery, when the voltage reaches the highest battery voltage (4.2V), the protection board will automatically power off and shut down, indicating that it will not continue to charge when fully charged, form an overcharge protection
- Over-discharge Protection: When the battery is about to run out and the voltage is as low as 3.0V, the protection board will also be turned off and can no longer be discharged, forming an over-discharge protection effect
- Short Circuit Protection: When an accidental short circuit occurs, the protection board will automatically shut down within a few milliseconds and will not be powered on again. Note that the cell is short-circuited (not through the protection board). The protection board will also fail due to continuous high current, or the components are heated and damaged
- Note: The battery overcurrent protection is not a panacea, please do not continue to charge and discharge high current, or the current and voltage beyond the range, otherwise the protection board will be damaged and invalid
Details: 1. Charging 1.1 Charging current: Charging current shall not exceed 1A. Charging with a higher current than the recommended value may cause problems with the charging and discharging performance, mechanical performance and safety performance of the cell, and may lead to heat generation or leakage 1.2 Charging voltage: Charging voltage shall not exceed 4.2V. 4.2V is the maximum limit of charging voltage, and the design of the charger shall meet this condition; if the battery voltage is higher than the rated voltage, it may cause problems with the charging and discharging performance, mechanical performance and safety performance of the battery cell, and may lead to heat generation or leakage 1.3 Charging temperature: The battery must be charged within the ambient temperature range of 10°C~45°C 1.4 Prohibit reverse charging: Connect the positive and negative terminals of the battery correctly, reverse charging is strictly prohibited. If the positive and negative terminals of the battery are reversed, it will not be possible to charge the battery cells. At the same time, reverse charging will reduce the charging and discharging performance and safety of the battery cell, and will lead to heat generation and leakage 2. Discharge 2.1 Discharge current: Discharge current shall not exceed 1A, high current discharge will lead to a drastic reduction in the capacity of the battery cell and lead to overheating 2.2 Discharge temperature: The battery must be discharged within the ambient temperature range of -10℃~60℃ 2.3 Over-discharge: During the long-term unused period, the battery may be in some kind of over-discharge state with its self-discharge characteristics. In order to prevent the occurrence of over-discharge, the battery should be regularly charged to maintain its voltage between 3.7V and 3.9V; over-discharge will lead to the loss of cell performance, battery function 3. Parameters Nominal Voltage: 3.7V Charge Cut-off Voltage: 4.2V Discharge Cut-off voltage: 3.0V Minimal Capacity: 2000mAh @0.2C discharge Typical Capacity: 2060mAh @0.2C discharge Standard Charge Method: Charging the battery initially with constant current at 0.2Candthenwith constant voltage at 4.2V till charge current declines to0.02C Max Charage Rate: 0.5C Max Discharage Rate: 0.5C Charge Temperature: 10~45℃ Discharge Temperature: -10~60℃ 4. Note 4.1 The lithium polymer battery should be stored in a cool, dry and well-ventilated place. And should be kept away from fire and high temperature 4.2 Keep the storage capacity preferably at 30%-50% (at a voltage between 3.7V~3.9V) 4.3 If the battery has been stored for more than six months or longer, the battery must be recharged 4.4 Batteries should be stored within the above temperature and humidity ranges 5. Package Content: 2 x 3.7V 2000mAh 7.4Wh Lithium Polymer Batteries
