Internal Lithium Battery / Lead-acid Battery Residual Capacity Display Module w/ 1.7 Screen - Black

All types are inside£¬ you can choose it yourself£¬ just press the button! 2-15 series lithium battery & 12V 24V 36V 48V lead-acid battery. The device is a universal residual capacity display module for the rechargeable battery£¬ suitable for rapid battery capacity detection of the lithium battery£¬ lead-acid battery on various instruments£¬ measuring equipment£¬ mobile equipment£¬ cleaning machine£¬ the balance car£¬ the battery car and so on. The battery symbol displays intuitively and the percent accurately displays. A high contrast LCD screen is used and can display for a long time in the dark or bright light. Instructions for use: 1. Solder the attached two-core cable (the red and black wires) to the positive and negative electrode of the battery£¬ the red is connected to the positive end£¬ and the black is connected to the negative; note: the connection shall not be reversed£¬ the reverse voltage above 15V may burn the electricity board! 2. The back of the electricity display module has a two-core socket£¬ insert the white terminal of the two-core cable into the socket£¬ pay attention to the socket direction; the electricity display module should work normally£¬ the backlight keeps on. If it cannot display£¬ you should immediately cut off the power and check to exclude the problem; if the electricity is always 0% or 100%£¬ please confirm whether the specification of battery and the electricity display module match. 3. The 5 battery icons on the left of the electricity display module LCD screen represents the battery capacity from low to high; at the same time the percentage shows on the right; 4. When the voltage is lower than the minimum value£¬ the percentage is 0%£¬ while the backlight off£¬ enter the power-saving low consumption state; 5. To prevent components on the PCB board from the equipment leakage damage £¬ special attention is payed to the instrument or metal casing which is not exposed to any metal part of the PCB board£¬ including the liquid crystal pin. In addition£¬ the back of the electricity display module should not touch any metal parts in case of short circuit; try not to touch the PCB board element with bare hands. The back of the electricity display module has a white keys£¬ used to select battery types. 1. First power off the electricity display module£¬ press and hold the key on the back£¬ then power on the electricity display module£¬ release the Kdn key£¬ the English sign: "xP" or "xC" is shown on the right (P stands for lead-acid£¬ C for the lithium battery£¬ X for the battery string number)£¬ press the key to sequentially display the types 2.Power off the electricity module after finding the corresponding type£¬ re-power it and it can function normally. Note: 1. The numbers in the nominal voltage is the general name of the voltage by users£¬ the same battery strings£¬ may have different names. 2. The lithium battery is the general three elements or soft package/polymer lithium ion battery£¬ not including phosphate ( iron-lithium ) battery. 3. "Code" means the the corresponding English character displayed on the LCD screen when selecting the specifications.
