![]() To correctly charge any deep cycle battery there needs to be some form of temperature compensation. Lifeline Charging Voltage at Different Temperatures for a 12 Volt Battery* Temp ☏ There are many converters that only put out 13.6 volts! All deep cycle battery manufactures require 14.2-14.8 volts to charge a battery. I have found where my charger my 28′ FB is putting out 13.8 volts and the battery was only getting 13.3 volts at 18 amps with factory 8 gauge wiring. This will give you voltage loss that needs to be accounted for. Many RVs come with a thin gauge wire between the charger and the battery. There needs to be a way to adjust the Absorption and Float voltages independently for your battery’s requirements and adjust for wire size. Converter chargers (what comes with most RV’s) do not have the ability to change voltages or provide temperature compensation to the charging voltage. The second most common is overcharging the battery. The most common reason for short battery life is not charging the battery to 100%. This unit will put out ~35A of charging into the battery/trailer useage. I don’t feel warm and fuzzy with auto mode myself. RV SMART CONVERTER MANUALIf you manual push mode and hold mode button the converter will stay in that mode for 2 hours before switching to auto mode, the unit will self determine the ‘correct’ mode. Boost mode is 14.4v – steady green light, Normal mode 13.6v – fast flash and Storage mode 13.2v – very slow flash. This converter has the Charge Wizard which will automatically switch between 3 modes. Above is the standard (not Lithium) version. RV SMART CONVERTER SERIESOur ATC trailers have the Progressive Dynamic Intel-power 4500 Series power center in them. RV SMART CONVERTER FULLIf that is true one would believe it will take 150 hours to charge 230AH battery bank, that is over 6 days! The problem is that no battery manufacturers tell us to charge a battery for 80-150 hours to achieve a full charge. ![]() ![]() From Progressive Dynamics website – A typical 125-AH RV or Marine battery will take approximately 80 hours to recharge at 13.6 volts. Most people believe that the RV converter will completely charge your RV batteries, this is simply not true. Unit requirements: below 50dB (A) measured at 1 m distance with fan full working.The quick answer is no, even high end RV’s come with inadequate converters that can not charge your battery correctly! (On the heat sink of DC-DC part, if the temperature is over 90 ℃, the Charger Current will be de-rate to 50% if the temperature is over 105 ℃, the Unit will be shut down.) Operating Ambient Temperature range: -10☌ to 40☌ | Nominal ambient temperature: 25☌ ![]() When the battery temperature is over 50 ☌, unit will shut down. When the battery temperature is over 40 ☌, unit will reduce the charging voltage to Float voltage, also it will reduce the Max charging current by 10% with every two degree of temperature rise. The battery temperature sensor allows the charge controller to continuously adjust charge voltage / charge current based on actual battery temperature. Unit will restart when environment temperature cools to 95 ☌. Based on these measurements, unit will shut down if the temperature exceeds 105☌. The internal temperatures of the charger will be measured by NTC. Vcharging (target) + 1.0Vdc for more than 2 seconds unit will restart when voltage Vcharging (target) + 1.5Vdc for more than 2 seconds unit will restart when voltage <= Vcharging (target) for more than 2 seconds.įor battery OVP the unit will restart in the same stage. ![]() 107.1ĭescription Battery Charger – 75 Amps for 12V Input Voltageĩ6-145VAC full performance | 70-96VAC automatically de-rate to 50% of full load current
