Re: Lithium iron phosphate batteries LiFePO4

I'm not totally convinced. Back then (2006-2007) you had to specify which set up you wanted for your Charge Wizard add on for the PD 9100 for wet cell or AGM. Maybe since then they have got it all...

Re: Lithium iron phosphate batteries LiFePO4

Fastpaddler,

It may not be that simple. You charge your battery through a Progressive Dynamics PD 9200 series converter. That has their Charge Wizard 4-stage intelligent charging built in for...

Re: Lithium iron phosphate batteries LiFePO4

Gerry,

It sounds as if you are trying to rationalize yourself out of lithium ion batteries. Like Marko said most RVs are basic and generally have idiot lights to tell you the status of your...

Re: Lithium iron phosphate batteries LiFePO4

Gerry,

People run their batteries down all the time but that really is not the issue I don't think. I think the discussion here is not one and two auxiliary battery systems. There is nothing to...

Re: Lithium iron phosphate batteries LiFePO4

The ARV release was specifically addressing the available amp hours between charging needs based on the recommended draw downs of 80% li-ion vs. 50% AGM. There are people that say you can draw down...

Re: Lithium iron phosphate batteries LiFePO4

Marko,

I'm not an expert on this stuff. But yeah if one reads my analysis it doesn't seem I could use all that battery power. It is going to be interesting. There are some Advanced RVs already out...

Re: Lithium iron phosphate batteries LiFePO4

When I say is there a difference I mean this stuff is all averages and guesstimates it seems. When they put meters on this stuff the readings are generally close and not exact. In other words if you...

Re: Lithium iron phosphate batteries LiFePO4

Is there any difference? Isn't an amp hour an amp hour? The only thing that I've read is LiFePO4 batteries can be discharged at a higher rate and last longer without diminishing its capacity. That...

Re: Lithium iron phosphate batteries LiFePO4

The Advanced RV charges the batteries from shore power. I would hope they have an intelligent battery charging system figured out because one thing you cannot do is overcharge lithium batteries...
