Someone shared a link to this on the Bronco Sport forum. I found it very helpful and interesting so I thought I would share here as well.

Huh, explains why I had a problem with my old 2012 f150 I had before I got the Maverick.
I have a work truck so my personal truck would sit at my shop all week, well I took a couple week trip for work and came back to take my personal truck home for the weekend and it had a dead battery.
I charged it with the battery charger at work but it wouldn't start till I jump started but I would literally have to jump it each time to start it after so I just ended up replacing the battery, then I got the call my Maverick was in two days later while I was in the middle of changing the breaks on it.
I'm not upset about the bms though, I got a Chevy work truck and so many times I have woken up with a dead battery on it because I forgot to unplug my cooler while I never had that problem with a newer Ford.
So thanks for the video showing how to properly charge the battery because I'll probably run into this issue with the maverick eventually.

Excellent explanation of the BMS operation. Thanks for sharing.

Great video. It helped me to understand how charge a late model car battery and why. A little tip if you drive short trips. Turn off your DRL (daytime running Lights) It will increase your charging rate on the battery and lower the draw.

Can someone tell me where to find a battery monitoring app like the one in the video? Does FORScan have one?

He had the ignition turned on as he was explaining.
Yes. With Forscan, you can pick the sensors you want to monitor. As an example, I have played around with a few, including the engine coolant temp, amps going into the battery, and battery state of charge. I use a wireless Bluetooth dongle in my OBDII port.
The Windows version has more features, but this is nice for when I'm mobile.

Thank you!!! I take delivery of my '24 Mav Lariat EB tomorrow and will be anxious to see if FORScan has been updated for MY 24 (I had read last month that it didn't yet work on 24's).Yes.

An important takeaway from the video is that his truck has an AGM battery. The BMS system is configured to monitor and work with an AGM battery. Most of us didn't have the AGM batteries installed during production and had regular batteries due to a supply shortage. Thus the "sleep mode" messages. Also, with the Hybrid, you can connect an overnight trickle charger to the battery (underneath the rear seat) by connecting to the positive terminal, just don't connect the trickle charger's ground to the negative terminal of the battery, just ground it elsewhere and this will allow the battery to fully charge. You can do a jump the same way. Doesn't mess up anything. Just don't ground from the battery terminal.

I believe that folks on here got it to work with a newer version of Forscan than was available on their site. The link should be floating somewhere around here. Good luck!

It should work fine. I replaced the AGM battery on m 2018 F-150, and I had no problems.
The following is a screenshot of my BdyCM settings prior to me messing with anything. They have the battery type set to AGM from the factory, despite giving us flooded batteries. It has been speculated that this may be a cause for the short lifespan of the stock batteries. BMS doesn't manage them correctly and inadvertently ruins them.
Two-ish months in with an AGM battery in my truck, not on fire yet. The charging system still doesn't really replenish what I lose to idle drain during my short commute (1-2A output is nothing), but I've been using FORScan to monitor the charge level. Have to hook it to the wall every ~3 weeks or so to keep it above 50%.
