It is suitable for network devices, smart devices and LED lights that support wide voltage.<br/>Product Version:<br/>2S version: Connect 7.4V-8.4V battery<br/>3S version: 11.1V-12.6V battery<br/>Battery capacity supported: 2-15Ah, 15ah under 2S is equal to about 110Wh, which can load 50W equipment for more than two hours, 15Ah under 3S is equal to about 166Wh, which can load 50w equipment for more than three hours, the battery capacity exceeds 15ah, the charging state is uncertain, and it is estimated that the battery cannot be fully charged and only part of the battery can be charged. Please analyze or test the specific effect!<br/>Battery types supported: It can be connected to conventional lithium-ion batteries or polymer batteries or 18650, 21700, 26650, 32650 and other cylindrical batteries, but it is not recommended to use inferior batteries or remove the battery, because the battery parameters are not consistent is easy to damage, unless you have a battery measuring instrument, and inferior batteries are prone to high temperature when discharging at large current. Overheating of batteries can cause fires or explosions<br/>Input voltage and charging: 2S version is recommended to input 9V, and can also input any voltage between 9-15V. It is not important whether your power supply has a charging function, because there is a professional charging chip on the motherboard, which can charge 2S battery to about 8.2-8.4V. 3S version is recommended to input 13V, which can charge 3S battery to about 12.3-12.6V. When the IN voltage of the 3S version is lower than 13V, the state of the LED indicator is uncertain, which may be bright, flash, light and shade gradually changing or out, but it does not affect the charging and can be ignored.<br/>If there is no suitable power supply, the IN can also be connected to 12V power supply, and the battery can be charged to about 11.7-11.8V. When the IN input is 12.5V, the battery can be charged to about 12.2-12.3V. When the IN is above 0.5V, the battery can be normally charged or displayed.<br/>About the charging current: the default current is 1.2-1.4A, about 11W in 2S, and about 15-16W in 3S.</p><p>Notes and Tips:<br/>1. If you are connected to the motor or electromagnetic load, please connect a capacitor of several hundred micrograms IN parallel in the IN interface to offset the interference or current impact caused by the electric spark, otherwise it will affect the life of the chip<br/>2. The constant voltage UPS means that the output voltage is equal to the battery voltage when discharging, and the output voltage is not boosted or stabilized. The output voltage will gradually decrease with the battery voltage when discharging<br/>3. The battery should be connected at the end of the assembly, so as not to damage the motherboard by the wire tip thrown on the component. Remember to charge and activate after the assembly is completed, and the output also needs to be charged and activated in a short time to have output<br/>4. The input interface can not be reversed, because the current is too large to support reverse protection<br/>5. Tip: The battery can be bare connected when making low-end products. If the conditions permit, it is recommended that the battery be equipped with a protection board and a balancing board<br/>6. Battery capacity support range: 2S or 3S batteries support 2-15Ah, and the default charging current limit is about 1.2A-1.4A<br/>7. The discharge indicator is slightly bright when the load is higher than 50-100mA, brighter when it is higher than 0.5-1A, and the brightness reaches the upper limit when it is higher than 2A. The charge indicator is effective when IN&gt;BAT 0.5V. Constant light = charging, out = charging end, flashing = abnormal<br/>8. Hint: At reverse output, the path loss is about 80 milliohm for 2S, 50 milliohm for 3S, and -0.1V for 2A load<br/><br/>Shipping list: Module x1<br/></p></div></div><br/>
