Product Details

The D250SE is a highly efficient and fully automatic dual input 20A charger, designed to cater to 12V lead-acid or lithium service batteries with capacities ranging from 40 to 300Ah. This advanced charger operates in 5 steps, ensuring precise and optimized charging for better battery life and performance. It offers selectable charge algorithms for AGM and lithium batteries, providing versatility to suit different battery types. With dual inputs, it can draw power from both an alternator and a solar panel, allowing for seamless charging even on the go.

One of the remarkable features of the D250SE is its intelligent battery separation function, eliminating the need for diodes and VSR relays. When the service battery reaches full charge, the D250SE automatically redirects maintenance charge power to the starter battery, ensuring both batteries stay in optimal condition.

The charger is equipped with a temperature sensor, enabling it to adapt its charging process based on weather conditions, ensuring optimal charging efficiency regardless of hot or cold environments. Additionally, it maintains a stable output of up to 20A to vehicles equipped with smart ECU-controlled alternators.

Compatible with various 12V lithium batteries such as LiFePO4, Li-Fe, Li-iron, and LFP, the D250SE is a versatile and reliable power management solution. It boasts a splash and dust-proof design (IP65) to withstand various environmental conditions, making it suitable for both indoor and outdoor applications.

For those seeking a comprehensive power management solution, the D250SE can be used in conjunction with SMARTPASS 120 and SMARTPASS 120S, providing an ultimate 140A power management setup.
