what kind of battery charger is this? I do not want one that will boil my RV batteries. If charge controller, how many stages?

It's a renogy pmw30cc - pmw type charger 30 amp max charge controller. It auto selects between 12 and 24v systems. If you hook the load up to the controller it prevents over discharge. As for charging, it will switch to float mode when batteries are 100%. The manual says nothing specific about charge stages/modes but does list the following: load disconnect 11.1v/22.2v, load reconnect 12.6v/25.2v, equalization voltage (30 min) 14.6v/29.2v, boost voltage (30 min) 14.4v/28.8v, float voltage 13.6v/27.2v, battery type sealed lead acid and flooded.

It's a pwm controller so it works in stages it doesn't overcharge my battery. I think its sable at 13.6 volts when it shuts down to charged mode. I only use it when im camping so I can't be sure. But it works great with 2 100 watt panels.

I use a Genius G3500 Charger/Maintainer. It has a special charging mode for AGM batteries. Just make sure to use a charging system that is smart enough to charge and manage AGM batteries. By the way, the Vmaxtanks MR107 12v 85AH battery is wonderful. I highly recommend this product.

My understanding is the battery charger auto controls the charge to the battery. Therefor the battery will not overcharge and boil the water out.

I use my charge controller with a 12 volt converter, but I think you can put as much power in as you want,and that it will charge a 24 volt battery bank.Since I have 12 volt converter, I had to put all my 12 volt batteries in parallel, so as not to go above 12 volts and exceed the converters volts

Anyone crack one open and see if this is anymore than a transformer and a couple diodes or is it an active charger that dials back the voltage or current when the battery is charged? Thanks. (I know it's only $8, but still wondering)

i use it to charge two deep cycle batteries on our camper. the batteries do not get heavy use but it does the job.

I am using a car battery charger bought at (B&D;) Walmart and it works fine. The battery charger need be "smart" enough to sense when the battery is full and automatically shut off. Overcharging a sealed lead acid battery would not be good.

hey Icepuck, did this work? Could you do same with a battery charger I am wondering? Im trying to run 12v lights off a generator and trying to find a solution... FF here too and rigging out a response trailer..

Is this just an expensive charger (snake oil) or will any battery charger charge AGM batteries? I already have 2 chargers, small 10 amp max and a full blown starter/charger.

What is a Trojan T605? I use the Flow-Rite on my RV (Class A) coach batteries (4 6V) and it works perfectly? and it vents the batteries and allows quick and easy filling of batteries

Good question. I would ask the manufacturer I had a question of them once and they were fairly prompt in answering. With mine I only need to connect to the batteries on my pick up camper and charge away!

My sensor is refereed to as ABS-248 in my instruction manual. I believe the sensor is built in. There is separate wire that I attach on the positive terminal of the battery. From the directions, that should activate the temperature variable charging function. I have three batteries lined up this winter that I keep charged with this charger. My RV (Optima Blue Top), Interstate Gel boat battery, and my deep cycle acid cell basement sump pump back-up batter. It charges each depending on need, then drops down to maintenance / desulfination mode. This charger does it all!

you will need a 10 amp charge controller for one of these or a 20 amp charge controller for two.The charge controller will have adjustable settings "you set"I suggest a renogy 30 amp pwm controller for three reasons it will give you room to add more panels its cheap under $35 and its all you would need to accomplish battery charging in 12 or 24 volt mode,I hope this helps

the battery has to be disconnected from whatever the battery is powering, otherwise you charge not only the battery but also the connected car/RV etc. This can be harmful to your cars electronic or the charger itself. I sell these chargers (6 volt version) with my battery powered pet fountains and had no complain over many years.

Any 12 volt battery charger will work. Just search for 12 volt charger and maintainer and expect to pay $10 to 20. I use Battery Tender Junior 021-0123

The battery charger is designed to charge the batteries and not to act as a power supply. I do have a new model just out that will milk olmost 4 gallons of milk. I will be putting it up on Amazon very soon. If you are interested in that milkier right now please let me know also send me youre e-mail address the new unit is 109.00 and shippingThank YouDanDansha Farms

This is a computer controlled 3-stage charger. Stage 1 is Bulk Charging; Stage 2 is absorption charging; Stage 3 is Float Charging and will be continued until the battery is charged. Once it's charged the unit stops charging. Periodically (it has to be connected to the battery) the charger checks the battery and initiates a float charge as needed to keep the battery fully charged. Float won't hurt the battery and it will up to full all the time if kept connected.
