【Up to 48V Battery Bank】LiTime Balancer boasts 4 distinct connection ports, enabling seamless integration with 48V battery banks. This versatility is ideal for building a robust 48V battery bank, achieved by combining 16 units of 12V batteries in a configuration of 4 in parallel and 4 in series. Compatible with 24V, 36V, and 48V battery banks, it is a perfect choice for diverse applications, such as RVs, golf carts, trolling motors, and off-grid systems. 【Proactive Protection】The LiTime battery balancer is equipped with reverse polarity protection and high-temperature Protection. The robust reverse polarity protection mechanism offers you peace of mind against accidental wiring errors (do not reverse it for a long time). The high-temperature protection safeguards the battery balancer against overheating, a common issue that can lead to performance degradation and safety risks.【Prolong Battery’s Life Span and Cycle Times】With these comprehensive active balancing functions, the LiTime battery balancer not only optimizes battery performance but also extends its lifespan. You can squeeze the full potential of batteries and achieve longer cycle times and overall improved performance. Whether you use it for your recreational vehicle, energy storage system, or other applications, the LiTime battery balancer is your trusted companion for optimizing your battery's life.【Suitable for Multiple Battery Types】The LiTime 48V battery balancer is suitable for multiple battery types on the market, including LiFePO4, GEL, SLA (Sealed Lead Acid), FLA(Flooded Lead Acid), and other rated-voltage batteries within 3-20V. Compatible with an extensive range of battery types available in the market, it can cover all your needs.【Auto Balance Mode and Standby Mode】As a voltage difference appears among the connected batteries, LiTime battery balancer will auto start working until the voltage difference is under 10mV. The maximum working current is 10A, which works for all 12V batteries at all capacity. If the voltage among the connected batteries is less than 10mV, the balancer will automatically turn into standby mode, only drawing less than 5mA from the battery bank.
