IF you are going to charge the pod battery(ies) using your tow vehicle... Turn it around and use a set of jumper cables. They are much higher gauge and can move way more electrons faster.

Same thing applies that I said above. Only run it 30-60 minutes every other day. When on a generator the point isn't to fully charge the battery each day, it is to just put the most amps in that you can for the amount of gas you are burning. However, every 7 days you do need to fully charge the battery. You can use solar, if you'll be camping where there is no shade. Even a little shading on a PV panel will cut its output most of the way. I recommend 200 watts.

+1. And make sure they are a good set, not a lightweight cheap set of jumper cables. Do not use the Bargeman connection.

400 watts definitely won't run the converter in the pod, it has a large inrush current when it is plugged in for starters. The inverter in your truck may not run any charger, actually, since it is most likely modified sine wave and many chargers don't like MSW. The conversion from DC to AC back to DC won't be nearly as efficient as connecting directly to the TV battery.

+1. And make sure they are a good set, not a lightweight cheap set of jumper cables. Do not use the Bargeman connection. I would still like further information that is still related to my previous questions. 1. In regards to using my generator, I know that if I want AC to my trailer, I will need to connect the pod power cable to the generator. If I just want to maintain the charge to the pod battery, I'm assuming it would be more efficient to connect from the +/- battery charge terminals of the generator straight to the pod battery. As mentioned on my previous post, my pod is solar ready by ZAMP. Near my battery connections, are two unconnected and insulated leads marked with ZAMP pos & neg. Is this for solar panel connections, and/or generator connections? 2 Now in regards to solar power, with my pod being wired solar ready. Is the jack marked with the Solar Ready & ZAMP where a solar panel with charge controller is to be plugged in, and do I have to use a ZAMP system there? I believe I could purchase a much less expensive system elsewhere.

1) Charging with a generator, using it's 12v cable, will output less than 10A to the charging battery (ies), the Honda 2000i sends a max of 8 amps. If you plug the pod shore cable in, and charge through the built in converter/charger it will charge at (up to, as needed) 55amps. So much faster and more efficient to use the shore cable connection. 2) You can hook up any solar system, or assemble components as you want or need, within reason. The ZAMP connector is "SAE", an yes, if you want to use their plug.. that is where you plug in.. beyond that it's just wires run to the battery. Good things have been said about the Renogy 100w foldable system on Amazon, about $275. A SAE connector has to be sourced and installed, about $5. If you want to use the pre-wired ZAMP plug. Just as a note.. the alternator on my tow vehicle is rated at 200A, and my truck is as quiet or quieter than just about any generator out there. The trucks on-board electronics will charge my Pod batteries at as safe, and fast, a rate as they can handle, with jumper cables. |

Thanks for the reply back. The 100w foldable Renogy solar panel I actually put on my Amazon wish list yesterday. I also read the reviews, which sounded very good.
I'm guessing that those two unconnected pos & neg cables in the battery cable harness marked ZAMP, are to be connected if a solar panal is plugged into the ZAMP solar panel Jack. Is that correct?

On that I just have to say.. "I guess."
I actually understood them to be hooked up on delivery, but no doubt you will need to do it if it isn't done. I added a zamp connector to one of my battery box tops. The other has a cut off switch. |

Night #1 in the winterized r-pod, using only the furnace, (outside temp ~28 degrees, keeping inside temp ~65) no appreciable drain on batteries.

Furpod,
I hope I'm not pestering you with too many questions, but I'm just trying to get myself setup the most convient and effecient way to maintain my pod batteries before I go dry camping off the grid. Just to be clear, are you saying that if I'm using my Honda generator to maintain my pod batteries, I can charge them faster if I connect the pod power cable to the generator 120 vac receptical than if I connected the generator pos/neg batt charging output connectors straight to the pod battery with about 10' of about 4 ga cables? I know that higher voltage has less power loss through cables, but going through the pod power cord and back to the batteries must be 50' long, vs 10' and heavier cables. |
