Conqueror trailer battery charging questions

[Honu]

I received 3 of the panasonics and all tested dead ?

I got a email for the guy who actually makes the panels and asked for info ? fingers crossed lets see what happens

Optimas do not work well for this system (for what ever reason). I have always understood that the Optimas are not great for a charge/discharge set up.
Thanks

Not the Red or Yellow Top; the Blue Top should work fine.
I haven't tried one but am running the Sears group 31 Platinum marine battery now. After a bit more than a year, it's not holding a charge as long as it did new. I used to have access to an Intelligent Battery Tester but not anymore; I'm thinking of getting one for myself and seeing a real measure of this battery's health.

... now I realize that my first week will be camping without electric service...

We do not use a lot of juice while camping... just a fan at night and the 12v light in the tent as we turn in, so it may not even be needed, but my idea seemed easy as a back-up idea....

Some fans draw huge amperage as some lights do.
My LED & fluorescent lights draw almost nothing.
I wouldn't charge the way you're suggesting and I don't think that any inverter would be enough to power a charger for a boat battery.
Have you thought about a gennie? Or a real hook-up like OS-Aussie linked?

Or you could just take what is already being used by RV for charging the trailer

This is interesting. I don't think I've seen this talked about before. It is a bit less elaborate than what is usually discussed around here, and cheaper. Hmmm.

made a post here with info ! as I did not want it to get lost in other threads so duplicate post kinda

here is what I said in that post :




OK got a email back from the person that actually makes the electrical panels
I asked him if he had a manual and to explain the isolator switch and any other helpful info he has on the panel we could use

this kinda answered the questions about my fans dying !


this is what he said:

to answer all your questions, the battery isolator circuit breaker cut the battery power from the panel. If the isolator is switched off then there are no battery power on the panel, only 12V power from the charger itself. You can leave the power on to charge the batteries, because we use a dedicated battery charging Ic to charge the battery and it go in a trickle charge state with reduduced voltage not to overcharge the batteries.
The fans cycle life is aprox 4-5 years and then they should be renewed.

I hope this will help you.
