There are two versions of the XJ-D378: 12V and 24V, or 4S and 7S. It can be applied to Li-ion Lifepo4 batteries. D uring the truck power testing, the power exceeds 1000 watts and the instantaneous current reaches 1025A. Additionally, the voltage switches on its own.
Features:
1.Short circuit protection function with output short circuit safety protection design.
2.Overcharge protection function. When fully charged and circuit not cut off, it auto-starts overcharge protection, stops charging to protect battery and prolong product use.
3.Voltage stabilization protection function. It can identify wrong connections and stop supplying power to avoid overvoltage.
4.Constant current protection function. When power supply current is abnormally large, it starts overcurrent protection and cuts off power.
5.Anti-reverse protection function. After car ignition, it cuts off connection with car battery and prevents reverse charging.
6.Temperature protection function. It can withstand high temperature up to 65℃ in summer and -15℃ in cold weather.
7.Magnetic field protection function. In large magnetic field areas, it auto-starts this function for normal operation.
8.Spark-free safety function. With spark-free safety protection design, no sparks are generated during use for safe use.
Application
An automotive starting power supply with a BMS is adaptable. It is a lifesaver for cars with dead batteries, whether they are hybrid, electric, or conventional fuel-powered. It provides dependable starter help in challenging circumstances for off-roading and outdoor excursions. Additionally, it is essential for both professionals and amateurs involved in automobile rescue situations. It also helps automobile sharing services, car rental companies, and auto repair and maintenance shops.
