Lithium Battery UPS Charging Module DC5V 9V 12V Step Up Booster Module for18650 Lithium Battery UPS Voltage Converter Protection

<div class="detailmodule_html"><div class="detail-desc-decorate-richtext"><div> 5V 1A Parameters:         Input: 5V1A or above         Output: 5V1A (max)         Battery: polymer lithium battery, 18650 lithium battery. (Recommended capacity below 10000ma)    Input side: input voltage can not exceed 6V.   Battery: Reverse connection protection, short circuit protection, charging, reverse connection will not be bad.    Output: can only supply ordinary loads, can not be connected to other power adapters, and the connection must be burned, the output short-circuit is fine, the load does not sleep when the small current.  Volume: 33*15*4.5mm Wiring port: Input: IN+input positive, IN-input negative. Output: OUT+ output positive, OUT-output negative. Battery: B+ connects to positive battery terminal, B- connects to negative battery terminal.   Indicator light (you need to add): R+ for external power supply working status, G+ for battery capacity indication Battery capacity is indicated by the frequency of flashing, the faster the flashing, the more adequate battery capacity, and automatically extinguished when no load or uncharged. Jumper (J1): used to set the power of the external power supply, the default jumper is shorted, the external power supply needs to be more than 1A; when the external power supply is less than 1A, you need to disconnect the J1 jumper, it is switched to 0.5A power supply to give priority to supplying the loads, and the rest of the current will be transferred to the battery for charging. Caution:      The circuit board will heat up when charging, so when assembling the circuit board needs to keep a distance from the battery, secondly, the battery looks good polarity, do not connect the reverse, so as not to damage the management chip, when the circuit is working in the state of charging and using, there is no short-circuit protection, so as not to damage the device!</div> <div> 9V 1A/12V 1A Product Description: DC UPS 12V 12W UPS uninterruptible power supply control motherboard, for the design of routers, switches and other network equipment or infrared alarms with continuous power supply, the upper limit of the battery when fully charged can be output 1A current, the battery voltage is about to empty when the power can be output 8-9W power, the output of the short-circuit automatically shut down, charge again to restore, the battery empty before shutdown often appears to blinking tips blinking a number of times to enter the low-power! Protection and shut down the output! (Tip: input or output interface can be common negative, positive can not be shared, the battery terminal can not be common negative!) Reminder: the current motherboard has a charging time detection function, the default slow charging is suitable for batteries within 8Ah, change the jumper to fast charging for batteries within 8-15Ah. Developed for 12V 1.5A router or optical cat and high-power UPS motherboard can also be used for 12V 1A equipment! Charging requires a minimum input of 5V, charging current default 0.5-0.6A can not replace the customer's original charger, another jumper can improve the charging speed, if it is accelerated charging must be replaced by the customer's original power supply to prevent potential safety hazards, at least double the power to be able to, for example, the customer is using the power supply for the 12V 1.5A, if the rapid charging, you need to replace the power supply for the 12V 2.5A-3A. 2.5A-3A power supply, you need to keep more margin, because you have no way to know whether the quality of the power supply is up to standard! Please pay attention to this problem for all peers or users! Product Description: Input voltage: DC5V-12V (this voltage is the voltage when charging the battery) Output voltage: DC9V or DC12V can be selected (the default is 9V, you can also change their own jumper settings for 12V, in addition to the output voltage for the battery power supply voltage, if there is a charging input, the output will be equal to the input) Output power: MAX12W Board size: 50 * 20 * 6mm BAT connection please connect the battery in the last step, this is very important battery 3.7V lithium or polymer batteries. Battery capacity: 1-3AH (MAX 5AH) Note: Welding input and output at least 20AWG line, line length should not exceed 10CM, input if connected to the output will form a loop, the loop will lose 0.4-0.6mA current Charging Indicator Accessories Application Notes Indicator. Use common anode red and blue diodes. Blue light indicates whether the load; red light indicates whether the battery is charging, charging red light on, full red light does not light; red light flashing indicates that the battery is abnormal or not connected to the battery. Indicator lights need to configure their own recommended selection of red and blue indicators to be effective, other colors of two-color indicator is invalid. Note: The output of the control board is invalid when charging short circuit, so please use this function with caution! Note: The control board will heat up when working, so it should be installed at a certain distance from the battery!</div> </div></div>
