![]() ![]() One of the things I also like about the Powermax is that it can give you a reliable source of DC power whenever required in the campsite or anywhere you are. One of the things I appreciate about this converter is that it is highly useful whenever you need a good power supply. The product can offer a great solution whenever you need a good power supply. You can rely on it to work when you need it and won’t have to worry about RV converter fan not working issues for a longer time because of its durability. This product can give you the most value of your investment because it is advanced and versatile for its many uses. It will be worth your money for its great features and durability. Here’s a link to the site where I bought mine.One of the most dependable RV converters I found online is the PM3-55. The one I installed was the Progressive Dynamics PD4655LIV model designed for lithium batteries. After upgrading my batteries to LiFePO4 lithium batteries, I needed to also upgrade my charger. Progressive Dynamics now makes Lithium compatible chargers. This works, but you’d have to manually monitor the charge voltage then switch it back to normal mode when it reaches full charge. I used this feature to force it into bulk mode. Pressing the little button on the DC distribution block will manually switch it a specific charge phase. The PD4600 series converter/charger is not designed to charge lithium batteries automatically. Replacing the original charger with the new one was a breeze. If the charger is programmable, they will also be able to tell you the recommended settings for each charge phase. NOTE: For best results, contact your battery manufacturer for recommended chargers that are compatible with their batteries. Swapping out the old with the new charger was as simple as unscrewing a few screws and moving some wires. I upgraded the stock converter/charger in my RV with a charger that has multi-stage charging. How to Replace The Old Converter/Charger? If this is the case, it’s highly recommended to upgrade to a four-stage converter/charger. When these problems occur, you may also find that your batteries aren’t holding a charge and frequently need replacing. When batteries are fully charged, they keep pushing a higher voltage into the batteries which can cause overcharging, buid up of heat and gas, and a significant reduction in lifespan.They do not supply sufficient charge voltage during charging which may tripple the charge time or prevent your batteries from reaching a full charge.Single stage chargers simply push a fixed voltage into the battery at all times. Lithium batteries also have specific charging guidelines set by their manufacturer. Each stage has specific voltage and current profiles designed to get the battery safely to a full-charge without overcharging it. Lead-acid batteries (flooded or AGM) require a four-stage charging cycle. What’s wrong with older single-stage converter/chargers?īattery manufacturers have specific guidelines for properly charging their batteries. Secondly, it is a battery charger that will recharge your deep cycle house batteries. First, it converts AC electricity (from the shore power) to 12 volt DC electricity needed to keep your lights, and other 12V equipment running. It has two functions as the name implies. ![]() What does the converter/charger do?įirst of all, the converter/charger will be powered when connected to a 120 volt shore power connection or generator. There are even models that support the unique requirements of lithium deep cycle batteries. Many can even be programmed to the exact manufacturer recommended charge settings. Newer converter/chargers have multi-stage charging capability and are recommended for modern RV deep cycle batteries. Single stage converter/chargers can shorten the lifespan of your batteries by overcharging them. If your RV has an older single-stage converter/charger unit installed, then you should seriously consider replacing it. Is your converter/charger damaging your batteries? You’ll charge batteries faster and extend their life. Do your batteries a favor and upgrade your stock charger/controller to a smart charger/controller. ![]()
