Depends on if your current inverter/ charger has a lithium profile on its charging component. My Magnum Energy invertor/ charger has the the ability to configure profile specifically for lithium bank.

Trying to get this to work….. Seems like it's easier to get in a nun's pants. Getting error after error, 40 minutes so far.

This depends on your needs. I've spent many hours looking for a "build your own UPS" but pretty much all the inverter/chargers with UPS function and automatic transfer switches have a 20-30ms crossover time, which is long enough to possibly shut down some equipment. The easiest option is to size an inverter/charger for your intended load and run off the battery. Your load amps would need to be under the charge amp (ie. 60 amp charger with a 30 amp load), and the system would stay in a float state with utility power being directly transferred to the load.
It's not a great idea to keep these batteries at 100% all the time, so you would need to occasionally pull the plug on the charger and let the system discharge some.

happened to me too... trying to pay off the credit card balance... don't want to deal w/ the cash advance interest. I ended up removing all the cards and linking my checking account. Hope that prevents this issue in the future but I'm thinking this battery is the last big purchase I'll do on AE.
This just happened to me on a different item. Credit card company wouldnt fix. I had them set my cash advance limit to 0$ so it will get declined next time.
A little research shows it was a PP problem. People have been calling in to PP to get them to refund. I will do that next time im free.

Travel trailer is my use. I like dry camping and a few of these bad boys can run almost any electronic short of the air conditioner when paired with a 3k inverter
