Product Description

12V Charge Controller

About This Item

Introducing the Flexcharge TM 12V Charge Controller - the ultimate solution for protecting your batteries and maximizing their lifespan. This charge controller is a must-have to prevent overcharging, which can significantly reduce the life of your battery or powerpack. Your battery/powerpack has a limit on the voltage it can handle while charging, known as the Peak Charge Voltage. Without a charge controller, there is a risk of generating voltage higher than the peak charge voltage, which can deliver excessive current to your battery and cause damage to its cells.

With the Flexcharge NC25A charge controller, you can rest assured that your battery is receiving just the right amount of power. One outstanding feature of the NC25A charge controller is its diversion load output, which allows you to connect it to a wind turbine or other power source that may generate excess energy. This feature can be especially useful for enthusiastic cyclists or wind turbine users by providing a braking function or slowing down the generated power. You can connect the diversion load to two 1000-Watt work lights, allowing the excess power to be dissipated and utilized effectively. With many charge controllers only capable of handling high amperage, there are very few options available that can handle a high input voltage.

The Flexcharge NC25A charge controller stands out from the competition as it uses a mechanical relay to switch the voltage on and off, allowing for a maximum input voltage of 140 Volts. This is significantly higher than the average charge controller, making it the ideal choice for those seeking a controller with a high input voltage capacity. Not only does the Flexcharge TM 12V Charge Controller offer exceptional performance, but it also comes at an unbeatable price. After extensive research, we have found that no other controller on the market offers the same high input voltage capacity for such an affordable price.

Don't compromise on the safety and longevity of your battery. Choose the Flexcharge TM 12V Charge Controller and ensure efficient and reliable power management for your solar panels, battery systems, off-grid setups, and renewable energy projects. Upgrade to the Flexcharge NC25A charge controller today and experience superior performance at an incredible value.
