  • Lithium Battery Capacity Tester Charge Discharge Balancer Car Battery Repair

    Lithium Battery Capacity Tester Charge Discharge Balancer Car Battery Repair

    This Lithium Battery Charge/Discharge & Equalization Repair Instrument can optimize battery production process, so that the capacity test and consistency screening process can be combined into one process and completed automatically. After completing the test, the test results are judged and displayed for classification.

    The optimized battery cell production process is as follows, reducing the manpower and material resources of a testing process:

    Coating → Winding → Assembling cells → Spot welding and packaging → Injecting electrolyte → First charged and discharged to full capacity & consistency screening → Internal resistance screening → Qualified.

  • Solar Panels 550W 200W 100W 5W For 18V Home/RV/Outdoor Wholesale

    Solar Panels 550W 200W 100W 5W For 18V Home/RV/Outdoor Wholesale

    Solar panels are devices that convert sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. The electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries. Solar panels are also known as solar cell panels, solar electric panels, or PV modules. You can select the power from 5W to 550W.

    This product is a solar module. It is recommended to be used with controllers and batteries. Solar panels have a wide range of applications and can be used in many places, such as households, camping, RVs, yachts, street lights and solar power stations.

     

     

  • Battery Repairer 2-24S 3A 4A Lithium Battery Automatic EqualizerBattery Repairer

    Battery Repairer 2-24S 3A 4A Lithium Battery Automatic EqualizerBattery Repairer

    This equalizer applies to 2-24 series lithium battery, from 1.5V~4.5V Ternary lithium, Lithium iron phosphate, Titanium cobalt lithium battery.

    The equalizer starts the compensation with a button, stops automatically after the compensation is complete, and then warns. When the voltage is out of the range, it will sound a warning and display reverse polarity warning and reminder: after connection reverse, over-voltage (greater than 4.5V), low voltage (less than 1.5V).

    The equalizer does not charge the batteries during the balancing process. So do not worry about the risk of overloading. The speed of the whole balancing process is the same, and the balancing speed is fast.
