  • Active Balancer 3-21S 5A battery equalizer for LiFePO4/LiPo/LTO

    Active Balancer 3-21S 5A battery equalizer for LiFePO4/LiPo/LTO

    As the number of battery cycles increases, the rate of battery capacity decay is inconsistent, leading to a serious imbalance in battery voltage. The “battery barrel effect” will influence the service life of your battery. That’s why you need a active balancer for your battery packs.

    Different from inductive balancer, capacitive balancer can achieve the whole group balance. It doesn’t need voltage difference between adjacent batteries to start balancing. After the device is activated, each battery voltage will reduce the capacity decay caused by the battery barrel effect and prolong the duration of the problem.

  • 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.
