The following products are a sample of our wide variety of items we carry and service. Lewco has been in buisness in Newport Beach California since 1955. We specialize in custom made Marine Battery Chargers for industrial, commercial, military, and private boats. All models have Silicone Diode Rectifiers for long life and dependability. Isolated primary and secondary transformers are of the highest quality. All have AC and DC output breakers for safety, tap switches with six different power settings and an ammeter to monitor power flow. Our Full Service (FS) electronically controlled models feature individually controlled output channels. This allows for different size battery banks to be charged to the correct voltage. This group of machines allows gell cell and wet cell batteries to be serviced from the same charger.
