That's very difficult to read, largely due to white text on blue background. Anyone publishing white text on blue background online should be banned from the Internet.

IF you're on a Windows PC, just ask your browser to *print* the page to the "Microsoft Print to PDF" device.
It will render the text as black-on-white ... all 96 pages of it.
Unfortunately, it's just creating an image, so the embedded links won't work and you won't be able to search in the page for specific words.

Cut & paste, my friend.... cut & paste.
The lessons I take from this article are the following:
If you are going to utilize Lithium Iron batteries without a BMS, you had better understand the chemistry and limitations of exactly what you have and how to utilize it best.
If you are going to utilize Lithium Iron batteries with a manufacturer provided BMS, you still need to understand the limitations of that BMS and you need to ensure that your method of charging (alternator, solar, battery charger) is appropriate for the batteries.
The storage state can be one of the more difficult problems to solve. Many of my customers have large RVs that they winterize. The procedure for them has always been to plug in their shore power (which enables an on-board battery charger) and thats done. Storage battery charger settings need a second look. You can trick a lead acid style charger to leave a Lithium Iron battery charged at 50% by adjusting absorption and float voltages.

Interesting video - opening up a Battleborn battery and showing the parts inside and how they are constructed.

Worth watching if you are considering buying lithium batteries.

Is it OK to add a new (additional) battery to an existing 1-battery system (12v Duracell Ultra 92ah)? Existing battery is less that 2 years old with light usage. I’d get the same battery model to add capacity. I’ve been advised to get 2 new batteries. Hate to replace a battery that seems perfectly good...
Thanks

if it was within a few months of the existing and hadnt been too deeply discharged or not maintained?
maybe.
but 2 year old and new = old sucks down the new and ya end up with 2 junk batts within a few months
(assuming yer discharging, esp if ya dont fully recharge every cycle)

Hi everyone, my name is Charla and I’ve been helping out at Adventure Wagon and learning more about their interior system. I hope to build out a 144 someday and just wanted to leave info for anyone who needs a battery tray, electrical harness bundle, battery tray with wiring bundle or solar panels .

Was looking at the Storyteller vans with the Volta system where there is a large 10000wh lithium storage battery. 3600w inverter and large 50 volt alternator to recharge in a couple of hours. The Volta system can apparently only be purchased installed in an RV or semi truck and does not look like you can buy components. Are there sources out there for the components from other suppliers? Any forum sites where this is discussed would be nice?

10,000 wh in a 48 V system is 4 200 Ah 12V batteries in series or 8 100 Ah 12V batteries in 4S2P. There is not anything very unusual there. There are lots of choices. 3600W 48V inverters can be found everywhere too. The alternator is more of a challange. It seems integrating those with the system has been a challenge for many. So, components like that are nothing special. The hardest part is the system integration.

I expect they don't describe details for just that reason, but I am always wary when specs are thin.
If you do the following search:
You can see a lot of information and issues integrating a 48V alternator. Since I did not go that route, I really don't understand it, but the volume of issues steered me away from it.
