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.

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

(I’m a new owner of a 2017 144 cargo - partially built-out. Lots of upgrades planned. Love this site, so much to learn.)

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)

OK thanks. Looks like it's new batteries for me. And do I also need to upgrade the existing Sure Power 2314 -200 isolator if I get to 200ah of battery capicity? I think I know the answer.
