The controller with temperature compensation can charge the battery with more power when charging the battery, and will extend the battery life.
When the battery temperature is rated due to the influence of external conditions, the battery overcharge point protection voltage needs to be temperature compensated, especially for various valve-regulated sealed lead-acid batteries, because this battery Very sensitive to overcharging.
When using temperature compensation, the battery can be fully charged even in cold winter, and there is no need to worry about the deterioration of battery life due to overcharging in summer.
With overcharge, overdischarge, overload, short circuit, over temperature and reverse connection protection functions; with dual USB5V output, for mobile phone charging;
Easy to Use: Comes with a display that can clearly indicate the status and data, it can be conveniently switched modes and parameter configuration, suitable for home, industrial, commercial etc.
