Yet another battery thread

So ?  More buses burn from tire and brake fires and fuel leak than from batteries, by far.  Are you going to stop driving your coach too ?

Batteries (lead acid and lithium) burn from over charging.   Don't over charge or short out the battery and you'll be fine.  Tesla batteries have current links in them that blow if they are shorted out.

You aren't going to over current a Tesla battery pack unless you have a monster charger.  50A x 240VAC = 12KW, so no chance of that in a normal bus.  You could potentially over voltage them, but that is easily avoided with a proper charge controller.

Tesla battery packs have build in temperature sensors.  It is very easy to monitor what is going on within the pack.

Battleborn batteries have a BMS built into each battery.   There is zero chance of them starting on fire.

DO NOT USE CHEVY BOLT BATTERIES.

I was watching the military discharge the lithium batteries to dispose of some, they were treated like bombs,they had a special building you were not allowed to visit discharging the Lis02 batteries the young people were wearing Haz/Mat suits and masks.The military's has a lot of different compounds they use in Lithium batteries all deadly

Someguy, that "presenter" and all the linked videos, is/are selling lithium batteries.

In the old world, it would be branded as "paid programming"

Making golf cart batteries look bad is in his best interest.

The average new busnut needs balanced reporting, and does not have the money to be paying for power, that far into the future, when they have many more important things to spend it on.

Happy coaching!

You can download Morton's data spreadsheets.  The techniques and equipment he uses are good quality and he uses the same equipment and techniques on the lithiums and lead acid batteries.

The last video I linked was selling Trojan lead acid golf cart batteries, not lithiums.

The capacity and cycle lifetime of Tesla batteries has been extensively tested buy several parties.

My first impression of these videos was favorable.

Then I realized everything is his favorite.

I think that might be a tell.

I'm certainly no wiser after reviving this thread.

Here you read all the comments (it gets deep) then do what suits the old wallet and yourself GC batteries will work they have for many years and don't break the bank ? how many batteries in a RV's are going to be cycled 5000 times in a RV .that rv will be long gone before they cycle that many times

Not sure exactly what you mean here but there are some chemistries such as the standard LiFePO4 that are totally unable to catch fire. There are plenty of videos showing how much extreme conditions they take with zero issues. There are other lithium chemistries that definitely are more sensitive and volatile but all are NOT DEADLY. Sorry Clifford, that is simply not true and a disservice to those already confused about looking into lithium batteries.

Windy if you read I was speaking of the military lithium grade of battery they don't use a lifepo4 battery.The CO told me it cost almost the same amount they pay for the battery to dispose of them and I had interest because I help pay for it.I even got a tour of the Telsa battery plant in Sparks and they were working on a new battery to replace the older battery packs I think it was still lithium though

Did you look at the voltage and current versus time spreadsheets ?   They were generated with a datalogger.    Are you accusing him of  rigging test results ?

Besides, his results have been replicated elsewhere, particularly by Tesla cars and golf carts using FLA batteries.    The Peukert effect is real.

You might not cycle your RV batteries 5,000 times, but you will probably cycle them more than the 300 cycles that FLAs will get you.   And FLAs degrade sharply just sitting around.   

If you aren't going to use your batteries for a fridge, microwave or AC and you aren't going to cycle them deeply, or discharge them fast, FLAs will work.   But as soon as you start really using batteries for what they were meant for, all bets are off.

Here is what I'm saying.

I'm uncertain of what I should do.

As I see it, there are many here using all kinds of setups that are working.

And most of those people aren't too emotional about it.

Full disclosure: The purpose of my bus isn't simply for a home. While we will be full time, it will be used in a missionary capacity.

It is likely to be in locations where power is a premium. I'm thinking natural disasters or something like that.

So, I need to be able to go anywhere anytime.

I sold everything I own to execute this vision. I'm all in. Literally.

It's important that I get this side of things right.

Boiled down and without emotion, it's really a pretty simple decision:

Flooded cell or AGM will get you to your destination. The initial cost will be less but the lifespan will be shorter. You will also need to have more capacity going this route to reach the same goal since these batteries are best when not taken to less than 50% state-of-charge.

Lithium batteries will also get you there. The initial cost will be higher, but it will buy you less weight, more capacity (in the same physical space), less maintenance, quicker recharge, and longer life. But, you'll have to find a way to keep them warm if you every plan to recharge them in freezing conditions, and they will require a charger capable of outputting the correct voltage/amperage.

The big thing is how much cash you have for the initial setup. If you have enough for the lithium it will give you much more flexibility to be in conditions like you're describing.

You could always upgrade later to Lithium,they will come down in price as more manufactures  enter the market,LifeLine the premiere AGM battery Co has entered the market ,Johnson Controls, and Deka  are entering lol it want be long before you can buy those at Sams and Costco,My cost on a LifeLine LL12v100-27 is almost 1/2 the price of Battleborn. 27 is the group number the 100 is the amps  right now Lifeline only makes 2 the other is the LL-12V75-24. just wait it out they will get affordable if lithium is what you want
