Not seeing signs of battery boiling since I installed it.
Works as described by not over volting the batteries then the temperatures are hot and bumping up the voltage when the weather is colder. I've not seen any signs of the batteries boiling since I installed this during the summer and i am charging them from shore power. I see that it does a 4 hours boost cycle and when that is completed the voltage drops. Wish I had an easy way to check how much amperage is being pushed into the batteries once the boost cycle is done. FIRST - make sure all power is detached - meaning all cables are detached from the battery, shore power is unplugged. The ease of installing this will depend on your coach or trailer. The system side was easy - connect the "phone wire" to from the card back of the daughterboard to the motherboard, then the temperature wire to the front of the daughter board and run it to a battery. The hard part could be running the wire, the easiest way would be to follow the main wires from battery to the Power Supply. Some will be a straight shot. Mine was not but it was doable, I had to pull out the lower power unit to run the wire to the front of the unit. Ignore the steps below if you don't have to. Sorry for the quality of the pictures I took them for my own usage not to be published. You can see in the picture how the daugher and the mother boards connect and off the right right you can see the wire that need to connect into the front of the daughterboard. Pulling the lower unit was easy, you just need to be aware of how the wires connect to the upper unit. In the over all picture there is a panel to the left that need to be removed. Behind it, see other picture, you will see a yellow cap with black wires going into it - one coming from the lower unit. You need to take that cap off. The white wire is in the bus circled in blue, remove that. On the right were the fuses are the blue and white wires coming over the top need to be removed. (see over all picture, close up of fuses, and close up of lower unit with blue and white wires and the connecter wire between motherboard and new board attached.) After pulling the lower unit out you can see in the picture how the daughter and the motherboards attach. The wires from the lower unit that have to reattach to the fuse board are circled in light blue. I used a needle nose pliers to wiggle them back into place on the fuse board. It was easy and took a couple of hours since I am a neophyte to this and had to think everything through twice. I didn't take a picture of the Temperature guage wire attached to the front of the motherboard.Parallax Power Supply 4400TAU Temperature Compensation Upgrade for Converters

Upgrade to Parallax 8355 Converter/Charger
The 4400TAU module is an upgrade to my RV 8355 Converter/Charger. I am a new RV owner and have read many instances of battery failures due to electrolyte boil off as the float voltage is too high. This review is only for the install procedures at this time and I can say that the install was an easy task. I had to purchase a T-15 Torx (star) screwdriver to remove the cover panel on my 8355 Converter. The 4400TAU installed onto chassis and plugged into 8-pin port on Converter circuit board. The hardest part was routing the sensor cable from the Converter through the RV to the 12V battery box. I was able to route the sensor cable under my couch up to front of RV and into battery box through same access point used by 12V power cables. The sensor cable is then attached to battery negative post. With the 4400TAU my Converter will now know the battery temperature condition and adjust the charge voltage appropriately. When I initially powered up the RV the clear 8-Pin connection on sensor cable illuminated indicating that the charger was in Boost cycle. Time will tell if this was a good investment.
