Re: Lithium Ion Battery

Gerry,

We will find out sooner or later. I look at it this way. Campskunk is testing for Roadtrek. If he weren't he would be able to speak freely about what is in his B. Since he is not, I...

Re: Lithium Ion Battery

Yeah, but Roadtrek just spilled the beans on lithium ion. How is that going to go over? I think they have more up their sleeve on that Campskunk van. For one thing it appears they have installed way...

Re: Lithium Ion Battery

I know they originally announced lithium ion with the Etrek but I was under the impression no one actually bought one with that setup. I also see Jim Hammill stating that there can't be any retrofits...

Re: Lithium Ion Battery

The battery management will prevent you from charging with any source until the cells are above freezing. That's what Advanced RV has worked out. The Silverleaf readout shows you every single cell,...

Re: Lithium Ion Battery

Are we being watched? This was posted on Roadtreking:The Group within the last hour by Jim Hammill, the president of Roadtrek. :)

Re: Lithium Ion Battery

You might be right. I just wonder if they are over selling. I am a little confused on the 8 volts because I thought 10.5 volts meant 100% discharge. I'm sold somewhat on lithium ion batteries as I am...

Re: Lithium Ion Battery

Smart Battery is claiming a built-in each battery a battery management system. When the cells drop to 8 volts they just shut down. No more power for you. Same at the other end. When fully charged...

Re: Lithium Ion Battery

Here are a couple of websites that have installed LiFePO4 battery banks in RVs and Sailboats that seem similar to what Advanced RV is doing. There is a couple of years success behind them. They might...

Re: Lithium Ion Battery

Wincrasher,

You dare not over charge a lithium ion battery either. Lead-acid wet cell you just boil out water you can replace if you over charge. Lithium ion will distort permanently. I'm not sure...

Re: Lithium Ion Battery

There have been some Advanced RVs that had those batteries installed with a lot of energy management behind them, but they are no longer offering them. This is their strategy now:
