3. 3 Testimonial …..Test results: I have a motor home with an 85Ah gel battery. I discharged the service battery to 50%, according to the battery tank meter. I started the car and drove away for an hour in 80-90 km/h. After about one hour had the bulk charge from the D250S stopped and I had a battery at about 80%. We took a break after about two more hours and I checked again. To my surprise: FULLY CHARGED!!!!! This has never happened to me before. After just 3.5h driving with a half charged battery coming to a a fully charged. This means that I will wait with my planned installation of solar panels. …. It is the motor home manufacturers that don’t know how to charge the service battery. There IS a cure, but it seems like you have to fix it yourself…..

6. 6 SmartPass and D250S, Features and benefits Features –Battery Separator that eliminates diodes, VSR relays or similar devices. –Multi-step charging of service batteries up to 80A alternator, which reduces recharge time. –Separation of consumers and service batteries during charging, which increases expected life of 12V devices like bulbs, LED’s and other electronics. The battery could be charged from the alternator at a voltage that minimizes recharge time. (Patent Pending) –Over-temperature protection of service batteries, reduces charge current at high temperatures (Patent Pending) –Battery watch for service batteries –Maintenance charge of starter battery. Only one output from AC/DC charger –Solar panel regulator with Maximum Power Point Tracking, synchronized with other current sources –Simplified installation of remote batteries for bow thrust or anchor winch. Benefits –Maximized service battery life because the time when the battery is undercharged is minimized and deep discharges are avoided. –Maximized service battery capacity because charging sources (alternator, solar, wind) are synchronized and with maximized utilization of alternator. –Minimized time and cost for charging which reduces cost for engine idling and shore power utilization. –Minimized environmental impact due to minimized engine idle time and maximized battery life.
