Hokay, since no one on the forum provided an answer to my query I took the low road and asked Microsoft Copilot AI, " What does the parameter TargetSOC_Cfg (TSOCC) • % = Hex2Dec(****) • Range: 0 - 200 in the Ford BCM module control?" This parameter is found in @Livnitup's list of BCM module...

Related to what Maxx said, you can also charge your truck's LVB if it's plugged into a charger (FCSP in my case) and you press the power button and step on the brake pedal as if you were going to turn the truck on. Because the truck is plugged into a charger, it enters "full-accessory mode."...

Does any FORScan expert know what the Battery Target State of Charge % does? @Livnitup? The default setting is 80%. Is it the lower limit below which an OTA update requiring Inhibit Mode can't run? Obviously, it's not an upper limit as our truck can easily charge their LVBs to >80% SOC...

Yes, as I mentioned in my previous post, I can charge into the 90th percentile just by letting the truck idle plugged in in full-accessory mode: My basic question is, what is the use of that setting in the BCM module? Maybe an off-the-wall suggestion, but could the battery target state of...

I discovered something about an F-150 12V charging limit, but I am still trying to figure out what it means in the context of our EV trucks. Maybe it's a vestigial setting that's not applied to our EV trucks (otherwise, things get very paradoxical with the >80% LVB SOC requirement to enter...

Interesting. For me, 5.3 is not being offered as an update but it's in the App Store! I wonder why? I'm not running iOS 18 Beta.

The line in the above quote, "The 12V battery will wear out if this energy transfer is completed daily due to aftermarket loads draining the 12V battery down to 40% or lower," is ambiguous and probably misstated. "The 12V battery will wear out if this energy transfer is completed daily...."...

Microsoft Copilot answers on the care and feeding of AGM batteries:

What! You've only added 58 kWh in 72 hours on the charger! I've added over a megawatt-hour in just 60 hours on my FCSP charger (1,043 kWh), but somehow I only charged my HVB 2% (48% to 50%). Shameful and ridiculous. According to that, my HVB capacity should be 1,043 kWh/2% = 52,150 kWh. I...

@chl. The LVB will also charge if the truck is plugged into a charger (FCSP in my case) and the truck is turned on in full-accessory mode (when plugged in, if you step on the brake and push start, the truck enters full-accessory mode, for instance). I drive very little and I've kept my LVB in...

Stupid thought. While brushing my teeth last night (!), the idea popped into my head that maybe Ford has locked up BCM updates because some bad guy has found a way to hack into the truck and steal it by forcing a BCM update. Since I know little about FDRS, it's easy to have wild ideas! ? That...

Turns out I read this via an AI summary of a post made on this forum: https://www.f150lightningforum.com/forum/threads/caring-for-the-life-of-your-lightning-battery.10526/post-212948 (see 1st answer provided by @beatle). Other web sources say the optimal kWh performance temperature for Li-ion...

@chl. You could try a SEND LOCK in FordPass to make the truck talk to Ford servers, then go to your ford.com account dashboard and read the battery level to see what your LVB % SOC is. https://www.ford.com/myaccount/?gnav=header-account If your truck has to be in Inhibit Mode for an OTA...

My version of FDRS is 40.4.48. Downloaded July 10, still the same on the download site: FJDSSupport - FordServiceInfo.Com (motorcraftservice.com)

@Maxx. I've made similar observations with my truck. Two things to consider. 1. Maybe there is something wrong with the coolant temperature reading furnished by Car Scanner and the like. Or maybe it just reports the last temperature reading when the compressors were actually running? 2. I...

On the power supply amperage bit I also read on the Internet that the NEC 80% rule is for "continuous" loads, those that run for three hours or more. A fluctuating power supply is considered a "non-continuous” load. So, by NEC rules, it would be considered safe to draw up to 15 amps from a...

I thought I'd do a reality check here. I got my (Solar) Clore PL6100 power supply (it's BEAUTIFUL!). The reality of "it requires a 20-amp circuit" is that it comes with a 5-20P male plug on the power cord, not the typical 5-15P plugs on more modestly drawing power-hungry devices. I have...

The thing that probably still differentiates this cheaper charger alternative from a true power supply is that with a power supply, you can set the voltage you need to maintain and the power supply will maintain the line voltage within 0.1 V, i.e., it functions as a line conditioner, whereas a...

That's why I qualified my remark about his "power supply" recommendation with comments to the effect that his recommendation (a Noco Genius2 battery tender) wouldn't do "for a Lightning." If I ask Google Gemini what size power supply vehicle electronics technicians typically use for ECU...
