Shipping time depends on your delivery address.
The most accurate delivery time will be calculated at checkout,
but in general, the following shipping times apply:
Model: HX-4S-D22 Overcharge voltage range: 4.25-4.35v±0.05v Size: 34.7*35.5*3.6mm Over-discharge voltage range: 2.3-3.0v±0.05v Upper limit working current: 10A Working temperature: -40~+50°C Upper limit instantaneous current: 20A Storage condition: -40~+80 °C Quiescent current: less than 30uA Effective life: more than 50,000 hours Internal resistance: less than 100mΩ Short circuit protection: protection, charge recovery Charging voltage: 16.8V-17V
Note 1: In strict accordance with the diagram wiring 0V (B-), 3.7V (B1), 7.4V (B2), 11.1V (B3), 14.8V (B +), do not intentionally short circuit. Note 2: After the line is connected, it needs to be charged before, and it will have output. Note 3: When connecting 4 groups of batteries in series, please ensure that the voltage of each group of batteries is the same. If they are different, please fill each group of batteries separately and use them in series. In the discharge test, the battery with a fast voltage drop is a poor battery. Explain: Do not mix good battery and poor battery.
Note:
This protection board can not be used for LiFePO4 battery, xenon lamp, hand drill battery pack, electric fish battery pack, electric bicycle battery pack, baby car battery, 775 (4A) or above motor, 1W fisheye LED lamp.
The power range described applies to the following products:
Low-power inverters, massager battery packs, LED light backup power supplies, electronics, solar streetlight battery packs, monitoring backup power supplies, and other products. Note: For discharge products above 3A, the discharge rate of the battery should be more than 3C. Magnification calculation formula: 1C rate battery, 2000 capacity is equal to 2AH*1=2A upper limit working current. 3C rate battery, 2000 capacity is equal to 2AH*3=6A upper limit working current. The battery will be hot when using, that is, battery rate is not applicable, this situation can not be used for a long time, the battery will be damaged quickly. Package included: 1 x 4S 14.8V 18650 Lithium Battery Protection Board
