I don't think ensuring any new battery connected is fully charged is without rationale - the BMS has to learn a number of parameters of the battery and it should be much more efficient if it starts at a known state of charge. But, if the service manual doesn't say to do it - OK.

Am I correct in my recollection that the BMS reset procedure should only be run with a freshly charged battery connected?

What would you use for a charge controller? I see a couple of options that are commercially available, one from LegacyEV.com and one from OpenInverter.org, but they seem like they're more kits than off-the-shelf solutions - all the LegacyEV options seem to require integration with a host...

Yes! RockAuto has the Ford battery for $85.79 plus a $18 core charge plus $11.99 ground shipping. Seems like the best price going by far. Thank you! The direct link to the product page is https://www.rockauto.com/en/moreinfo.php?pk=15222013&cc=3446918&pt=2476&jsn=8 but note it displays...

This is a picture of the internals of an Ohmmu 12V battery. Ugh. I would consider Ohmmu a "name brand" in this space but if you're thinking of others, I'd love to hear about them.

Thanks, I was equipped with it earlier as well. I guess I will continue to "do me" which, in this case, means not incurring the risk of walking out to a dead vehicle in -20F weather because I changed to an LFP battery for the 12V system. Also not incurring the risk of fire or other issues...

You guys who are "levelling" your trucks because when the box is empty, the rear sits higher than the front - what happens at max payload? This has never made sense to me.

Hm, looks like the Toyota battery might not be an AGM - their part descriptions for a number of their "TrueStart" batteries include "AGM" but not this one.

Looking to replace my 12V starting battery as it's now 3 years old and has been discharged significantly a few times. The cheapest I can find the Motorcraft replacement is about $215 shipped. I see there are 3rd-party options that all cost more, but then I see a Toyota option (they stock it...

Load tests don't work as well on AGM or gel cells as they do on traditional wet-plate designs. I say this as someone who's been responsible for several large lead acid backup battery arrays in the course of my career. We replaced batteries on a fixed cycle, or sooner if there had been a major...

Should I back up every module before making any change with Forscan, ever? Hell yes. But do I? No, because it takes a minute or so per module and there are like 40 modules. I have a "golden" backup from before I ever changed anything, and then I back up only the modules I'm changing. This...

I wish Forscan had a "back up every module" button. Have never understood why it doesn't.

How long's that box, 4'6 or 5'? It looks even shorter than on our trucks.

No joke. Quick little bit of forscan work would enable the "Lincoln Navigator" auto-fold-on-lock feature for your mirrors. Highly recommend it given what the mirrors cost, and it also gives you a visual confirmation you remembered to lock the truck...

They're going for controls that have the look and feel of traditional ICE controls to avoid excess cognitive load for drivers whose first car wasn't a Lightning. I appreciate this - the first time I tried to put my 2015 Model S into neutral for a car wash, my head just about exploded, never...

My truck has developed a small "blacked out" area (about the size of a pea, with a "shadow" trailing away from it towards the truck body) in its 360 camera view. It's pretty much directly away from the front right (passenger side) corner of the truck. There must be something on the camera...

I wonder if they even sold 40 HIS systems honestly. I guess they must have.

Ooooh I'd be very, very careful about that with no way to synchronize the inverters. It's asking for trouble.

Can the inverter in the HIS actually supply 100A (when it works at all)? The marketing materials available when I bought my Lightning quoted a decidedly lower figure.
