The 230 volt BusPro-662 model is a multi-station 5 amp smart charger specifically optimized for use with AGM (Absorbent Glass Mat) Batteries. These completely automatic charging stations are ideal for fleets, shops, and parts stores due to the advanced new circuitry designs and controls specifically designed for the proper and safe charging and maintenance of AGM batteries which makes overcharge impossible. BusPro Series chargers utilize individual transformers and microprocessors for both low and high volume battery charging applications. This allows each channel to work independently and charge the battery correctly and in a timely manner. This unit has two LED lights per channel to visibly indicate whether the unit is connected, charging, topping off, completed charging, or a bad/reverse connection.
