2S/3S equivalent DC UPS power supply module DIY-2 two-way charging and discharge version of the load power 35/50W

Reminder: When using this product, please confirm that your power supply supports two -way mode. If you do n’t understand, it is recommended to buy 12.6V chargers online to drive the motherboard and load!

Product version: 2S version (connected to 7.4V-8.4V batteries), 3S version (connected 11.1V-12.6V battery) supported by battery capacity: 2-15AH, Chinese writing two drys to 15,000 to 15, no, no, no, notShao novice does not understand what AH is, so add a Chinese writing, 15AH under 2S is about 110Wh, you can load 50W equipment for more than two hours, 15AH is equal to 166WH at 3S, which can load 50W equipment for more than three hours. The battery capacity exceeds more than three.After 15AH, the charging status is uncertain. It is estimated that the battery cannot be fully charged. Only part of the power can be charged. Please analyze or test it by yourself!

Novice reminder: Wait for UPS to refer to the output voltage when discharge is equal to the battery voltage, and the output does not increase or voltage. The output voltage will gradually decrease with the battery voltage when discharging.Customized!

Supported battery type: can be connected to conventional lithium ion batteries or polymer batteries, or cylindrical batteries such as 18650, 21700, 26650, 32650, etc., but it is not recommended to use inferior batteries or disassembly batteries, because it is easy to damage when the battery parameters are inconsistent.Unless you have a battery measurement instrument, and the inferior battery is prone to high temperature when large current discharge, and the battery will cause fire or explosion when the battery is overheated.Modification is easy to cause accidents!

Entering voltage and charging: 2S version is recommended to enter 9V, you can also enter any voltage between 9-15V. It is not important whether your power supply has a charging function, because the motherboard has a professional charging chip, you can charge the 2S battery to 8.2-About 8.4V, the 3S version is recommended to enter 13V to charge the 3S battery to about 12.3-12.6V. The status of the LED indicator light when the 3S version IN voltage is below 13VDestroy, but it does not affect the charging, just ignore it. If there is no suitable power supply, you can also connect the 12V power supply. You can charge the battery to about 11.7-11.8V. When the input is 12.5V, you can charge the battery to 12.2-12.3For about V, it can be charged normally when IN is above 0.5V! Or display status! Regarding the charging current or power: 2S version is about 11W power when charging, and the 3S version is charging about 15-16W charging when charging about 15-16W.Power, please pay attention to calculating the external power power, and consult the power supply manufacturer by the way! Reminder: The assembly should be connected to the battery last, don't forget to charge activation!

Battery discharge and path loss: The 2S version is connected to 8.4V battery, the discharge range is 6-8.4V, the battery is automatically disconnected when the battery is about 6V, and the connection is resumed after charging! 3S version connects 12.6V battery, the discharge range is 9-12.6V, Automatically disconnect when the battery is below 9V, and can be restored after charging! The internal resistance of the 2S version is 70-80 mm, the loss of 0.07-0.08V when the discharge is 1A.The internal resistance of the 3S version is 40-50 mm, the loss is 0.04-0.05V when the discharge is 1A, the loss of 2A is 0.08-0.1V, the loss is 0.12-0.15V when the discharge is 3A.V-0.22V, remind the motherboard to increase the internal resistance when the motherboard is heated! The empty load loss of the 2S version of the battery interface is 0.3-0.5mA, and the 3S version is 0.6-0.8mA. Users should pay attention to calculating this data!

Dry current and function protection: 2S or 3S motherboards are rated at 4A when natural heat dissipation. As long as the ambient temperature is not high, 4A current can be output, which is equivalent to output 35W power at 2S.The voltage in the battery will decrease, which will cause the current to rise. This is a physical rule. Therefore, it cannot be fully loaded in actual use. Press the battery interception voltage to discharge the current.It cannot exceed 36W, otherwise it will cause the motherboard to heat up, and the component is overheated! The motherboard can also be output to the 6A current at the air cooling or hanging temperature control fan, which is equivalent to the peak output of 75W power. If the power continues to increase the power, the load current exceeds exceeding the load current exceeding the load current exceeding the load current exceeding the load current exceeding the load current.At 6-8A, overload protection or short-circuit protection will be disconnected, so even under the wind and cooling, it cannot exceed the 6A current, so as not to trigger protection. Of course, Over 10A currents will trigger protection! If the back -level boost or antihypertensive module, pay attention to calculating the start current! About the protection function: At present, only debugging and successful discharge protection and output overload/short circuit protection, input input, input, input, input, input, input, input, inputAnti -connection protection failed to debug, because the current is too large, and the current of dozens of people through the elements in an instant. Those small -volume elements cannot bear this current, so it will be blown up."

Input parameters: DC12V/12.6V or 15V, the input current should be greater than 6A, and the output parameters of the board indicator: rated current 4A (about 50W), peak current 6A, recommended load below 4A below 4A
