My Roadtrek, and it is listed as a drop in lead acid replacement. I just don't know what lead acid model a 20.5" x 10.6" x 9.1" $2,999.99 lithium ion battery would be a drop in replacement for.
Probably 1 replaces 2 batteries. which might be doable in a Rt. The post was more to demonstrate what the future holds for RV's, as I doubt few owners are going to spend $3,000 for a battery. I'm sure prices will come down, and when they do, it will open up a lot of options for the boondocker. For the short time boondocker, they could be made more affordable by not needing solar panels. Looks like they can be deep discharged, so 300ah would last a lot longer than other batteries.
A good way for a Claas B, which is space, and weight limited, to extend its off grid time.
"How long do they last?
Smart Battery™ advanced lithium technology will provide you with 2000 complete charge and discharge cycles at 80% DOD. After 2000 cycles, you will still have over 80% of usable energy left.
Example: A 12v 100ah battery, after being discharged 80% for 2000 cycles, is now a 12v 80ah battery."
There is a PodCast called "American RV'er" that interviewed a guy about a year ago that was beta testing LiPo’s in the coach. They run considerably longer, amazing capacity for their size (just ask anyone here that flies RC aircraft): one GC2 size battery takes the place of 4.. The thing is they don’t gradually just drop off, they avalanche OFF with little warning to the point that there are safeguards built into the battery, as in a reserve “area” just to start the engine or generator activated by a bypass button. He said he had no idea what they cost since he was a beta site and they would work that out later.
It’s worth searching this down and watching the video edition of it.
WOW, did you see the discharge rates and times for 60 amps and 300 amps. This will be a gamechanger for stand alone solar systems in remote homes. This even with the high cost will blow away the 6 volt Trojan battery banks and may even be cheaper when you consider the racking and storage venting.
Now in the RV a big pricy for me.
