A 80A charger won't charge any faster then a 35A charger.. batteries don't work like fuel tanks. You can only recharge at a percentage of the batteries capacity. and the battery charge rate slows considerably as it approaches 100%. Charging from, say, 50% SOC, the battery may take 4 times as long to get from 80% to 100%, as it did to get from 50% to 80%. When boondocking, we often don't get back to 100% SOC for a whole trip.. but we keep up enough to not fall below 50% SOC... |

GCRicker, The converters both 35 and 80 amp have 3 stage regulated charge circuitry. Many generators are built with unregulated charge circuits. Adding an inverter will allow the use of certain appliances and will require a shore power source to recharge the batteries. You could also add solar but it works much slower. Your standard converter should work fine. I think your mods should be along lines of solar, multiple batteries and a good generator source. Happy Trails.

It is very confusing Mike and you get different answers from different people. Since I will be using the RPod mainly for dry camping, I will be buying an inverter so I can watch TV and cook in the Microwave during the evening. This will drain the battery really fast. I need to charge the battery (or batteries) as quickly as possible by plugging the RPod into a generator during the day. My original understanding was an 80 Amp Converter will charge a depleted battery 2.3 times faster than a 35 Amp Converter. However, I think you and furpod are saying that I'm incorrect, and that they will both charge the battery at the same rate. I'm going to go to the RV dealer this weekend and hopefully get them to tell me what I need to do. I'll share with everyone what they tell me.

Need some help understanding. Both these converters charge in a conventional 3 stage way. Both charge at same voltage. What does multiple batteries have to do with post? That doesn't change what converter does. The converters will charge at their capability. What in an RPod environment would call for an 80A converter? A Rpod is a 30A compatible RV, what benefit do you get from a 80A converter? Doesn't matter about a generator, that's a shore power device. I don't suggest telling the OP he's offtrack and agree it's his money, but what does this provide or correct? Maybe I'm missing something. I'll bet both these converters operate at same amps on charge circuit, otherwise they would as Lark pointed out overcharge a single battery.

If you are going to deck mount, just buy the converter you want, and deck mount it right behind the 8735, just move the wires from the one, to the other.
EDIT.. Looking at the 190 floorplan pictures, it would appear you would have to put it to the side, rather then behind. No issue. |

Greetings: You didn't say if you are going to upgrade to dual batteries or a larger single. You can only charge a lead acid battery so fast. Anything else will cause it to use water, and shorten it's life. A deck mounted charger will work fine, but the 80 amp rating is for load, not so much for charging rate. It's your money, good luck.

If I'm getting off topic for this particular forum, I apologize.
From what I can tell, you can't replace the WF-8735P with something like Progressive Dynamics 9280 (80 amps), because there is no extra space where the all-in-one WF-8735P is in the RPOD. I found a post that said you could put a second converter, like the Progressive Dynamics 9280, up in the front storage (Close to the battery), and just turn off the breaker going to the old converter. I may do that, since I plan on buying a generator and will want fast battery charging. |

It looks like the best deals for converters is on Amazon. Batteries need to be put in a above freezing location with a "smart charger" during non use. The more you deep discharge a battery, the shorter the life. Jellcells will last longer but are much more expensive. Marine batteries for trolling motors will take more cycles. The most common battery size put in RV's is a group 24. I changed to a group 27 which will run longer. If you install dual batteries, make sure they are the same age otherwise they won't take a balanced charge Lark R=179

Your charger will work fine. It will raise the voltage as needed, trading for amps.. (Ohm's Law and all that). It will charger your battery to 80% +/- at a higher rate, then lower the charge rate, as do ALL chargers, creeping up to 100%. It will not, in any way shorten the life of the battery. 99% of batteries that "die an early death" are murdered by their owners. The other 1% are stolen, so no one knows how their life goes. Or, very very rarely, a battery breaks internally. If you do your part even a 2/6A charger can keep your battery going a long long time. |

The WF-8735P has a three level charging system. It will charge your battery and it won't take days.
