oops sorry about that, I put one extra charge in there, it should read "speed charge" in other words, quick charge, the opposite of slow or trickle charge.

so speed charge would include hooking up to your tv, correct?

Yes, In my opinion, that would be considered "quick charging"

Just to be absolutely sure, with 12 volt batteries, you want to connect them in parallel. This means connecting the positive terminal of one battery to the positive terminal of the other battery. The same goes for the negative terminals. If you connected the positive terminal of one battery to the negative terminal of the other, that would be a series connection and would create a 24 volt battery. That will create all kinds of problems and probably fry something (and not in a good way ). |

Correct, but with parallel batteries you always want to hook up the load or the charging source via the + of one battery and the - of the other. This allows for equal charge/discharge between the two batteries. If you only hook up to one battery, the resistance of the wires that create the parallel connection ensure the other battery will be discharged less and then charged less.
This is the primary argument for using two 6 volt batteries in series, since it removes that problem from the equation. |

last question. lets just say the batteries are discharged over 50%; how long would you think charging from the tv would take? hogone

That can't be answered without knowing the capacity of your battery.
But- for a 105 amp hour battery, since most tow vehicles can't deliver over about 10 amps, then from 50% you are looking at about 6+ hours. If it is the smaller 80 amp hour battery you are looking at about 5 hours. I have two paralleled 105 amp hour batteries and my tow vehicle with large wiring I installed puts about 13 amps into the batteries at idle- so in my case 50% down would take a whopping 9+ hours! Which Is why I don't charge that way unless I'm going to be driving a lot- on generator with the built in convertor it is putting around 35 amps into the batteries. The call it a 50 amp charger but I've never seen it actually put out that much. Don't forget charging requires you to put back more than taken out due to losses in the process. |

One caveat of catalytic heaters, the typical unvented ones put a lot of moisture into the RV, something many already struggle with even with a vented heater. I have a couple that are at least 30+ years old, one propane and one that even runs on Coleman Fuel...that thing was scary! Had to light it outdoors as it put out foot high flames until it warmed up and started to glow. |

We only dry camp. 3 days on a fully charged group 31 battery will work fine using the heater, water heater
water pump and led lights just fine. Ya we use the heater in the summer time here in Idaho. Have only camped for 3 days at a time but suspect the battery would go 5 days. I will be hooking up a solar panel that has self adhesive tape and will go on top of the pod this winter. Kind of like fuel in the tank, nice to keep the battery charged up as much as possible. This helps the life span also. Another year or 2 and the lithium batteries for RV's will be a decent price point. Considering the leading edge technology lithium batteries have a longer life span over a SLA battery, the cost is nearly the same per cycle now. Though the up front cost is steep. |
